What “Four Outlets + Safety” Means in Practice
The four-outlet safety build is the reason to choose the JH-GF005, so it helps to know exactly how it works:
- Four independently controlled outlets — Each outlet has its own knob, so you open and adjust each one separately, not from a shared handle.
- Four gas points from one fitting — All four outlets sit in a single deck-mounted body, so you get four controlled gas connections without installing four separate taps.
- Press-and-turn safety on every outlet — Each knob needs a deliberate press before it turns, which matters most when several outlets sit close together, and more people work at one station.
- Fewer deck penetrations — One fitting means one hole in the worktop instead of four, keeping a busy bench tidy and the installation cleaner.
If your bench groups four gas points at one location — and several users or active outlets raise the chance of an accidental knock — the JH-GF005 delivers that with built-in protection on every outlet.
Why the Safety Model Matters Here
The more outlets and users you group at one bench point, the more the press-and-turn safety earns its place:
- More outlets, closer together — Four knobs in one fitting sit close together, so a stray hand or a set-down flask is more likely to brush against a control.
- More users at one station — Shared and teaching benches see more traffic, and the deliberate press-and-turn action helps prevent an unintended opening.
- Higher-traffic worktops — On busy stations where reaching across the bench is common, the safety action adds a practical layer of protection during everyday work.
The safety function isn’t just a mechanism — on a four-outlet station, it’s the reason this model suits crowded, shared, high-use benches.
GF005 vs Adjacent Gas Fitting Models
All of these are laboratory gas fittings that share the same core build — a brass body, an epoxy finish, and a slow-opening needle valve with press-and-turn safety. The difference is the outlet count and where each one mounts:
| Model | Outlets | Mounting | Best for |
|---|---|---|---|
| JH-GF005 | Four | Deck-mounted | Busy shared benches and teaching stations that group four gas points at one location, where the safety function guards against accidental contact |
| JH-GF004 | Triple | Deck-mounted | Shared benches and multi-burner workstations needing three gas points from one fitting |
| JH-GF002 | Double | Deck-mounted | Shared benches and dual-task stations, with premium 59-1 / H63 brass and CNC-machined consistency |
| JH-GF001 | Double | Deck-mounted | Shared benches and dual-task stations needing two controlled gas points from one standard fitting |
| JH-GF009 | Single | Worktop-mounted | Individual workstations that need one dedicated gas point |
| JH-GF006 | Single | Wall-mounted | Benches kept clear, where gas plumbing runs along the wall |
| JH-GF003 | Single | Suspended-mounted | Island benches or service spines fed from overhead |
| JH-GF008 | Remote valve + cock | Fume hood | Gas control operated from outside the enclosure, clear of the work zone |
Choose the JH-GF005 when four gas points belong at one busy bench location, and you want safety protection on every outlet. Step down to the triple-outlet GF004 or a double-outlet GF001/GF002 when fewer points are enough, or the single-outlet GF009 when each position needs just one tap. If you’re unsure, tell us how many gas points each bench needs and how many people use it, and we’ll recommend the right model.

Key Features
1. Four Independently Controlled Outlets
Each of the four outlets has its own knob, so users adjust them separately. Several people can work at one station, or one person can assign each outlet to a different burner, instrument, or task — all from a single deck-mounted fitting.
2. Press-and-Turn Safety on Every Outlet
Each knob requires a deliberate press before it turns, so an accidental bump or knock won’t release gas on its own. With four outlets grouped close together and more hands at the bench, that protection matters more than on a single- or double-outlet fitting.
3. One Fitting Instead of Four Taps
All four outlets sit in a single deck-mounted body, so you get four controlled gas points with one mounting hole instead of four. That means fewer deck penetrations and a cleaner, more organized bench.
4. Premium 59-1 / H63 High-Copper Brass Body
The body is machined from high-grade brass with a high copper content and low impurities. In practice, that means greater strength, stronger resistance to deformation over time, and a longer service life under repeated daily use.
5. CNC-Machined Precision
The fitting is produced on modern CNC equipment. For you, that translates into more consistent sizing from unit to unit, a cleaner assembly fit, steadier valve action, and a refined surface finish — useful when standardizing many fittings across a lab.
6. Slow-Opening Needle Valve
The slow-opening action brings gas up gradually rather than surging when you open an outlet, and the needle-valve design lets you fine-tune the flow for controlled, steady delivery.
7. Matte Epoxy Powder Coating
A protective finish that helps the outer body resist routine acid/alkali splash, UV fading, and heat in general lab conditions, keeping the surface clean over time.
8. Ergonomic High-Grade PP Knobs
Each outlet is opened by a comfortable, high-grade PP knob shaped for a secure grip and steady control, easy to operate through frequent daily use. The knobs are also available in custom colors for gas-type identification across a lab.
Applications
The JH-GF005 is built for busy, high-use benches where several controlled gas points — and built-in safety — belong at one location:
- Busy shared benches — Four independently controlled outlets allow multiple users to draw gas at once from a single deck point, with safety protection on each knob.
- Teaching benches — The press-and-turn action suits student stations and high-traffic worktops, where accidental contact is more likely.
- Multi-user workstations — Several people work side by side, each on their own controlled outlet.
- Grouped gas-point layouts — Any worktop where four controlled outlets belong together, and reducing deck penetrations keeps the surface clear.
Its primary role is safe, multi-point gas control at the bench, providing busy shared and teaching stations with four clear, dependable outlets from a single deck fitting.
Installation & Compatibility
The JH-GF005 mounts through a standard laboratory worktop and connects to your bench gas service. Because it carries four outlets in one fitting, a few checks help ensure a secure, correctly matched fit:
- Confirm the deck hole in your worktop matches the fitting base for a firm, stable mount.
- Allow bench space for four outlets so several users can work side by side without crowding.
- Confirm the inlet connection matches your bench gas line and pipe fitting.
- Confirm the gas type — the right connector and configuration depend on the gas medium, so share your gas service details before ordering.
- Confirm the worktop material — let us know your countertop type if you’d like guidance on mounting before shipment.
Share your worktop details, gas type, and inlet connection, and we’ll confirm the right configuration for your installation.
FAQ
What makes the JH-GF005 a “safety” gas cock?
Every outlet uses a press-and-turn safety function: you have to press the knob before it will turn, so a stray bump or knock won’t release gas on its own. On a four-outlet fitting, where the knobs sit close together, and more people share the bench, that deliberate two-step action adds a practical layer of protection during everyday work.
Are all four outlets independently controlled?
Yes. Each outlet has its own knob, so you open, close, and adjust each one individually. That lets several users set different flows at the same station without affecting each other.
When should I choose the GF005 instead of the GF004 or a double-outlet model?
It comes down to how many gas points belong at one bench location and how busy that bench is. Choose the four-outlet GF005 when a station groups four gas points and sees heavy, shared use — the extra outlets and safety action suit teaching benches and multi-user worktops. Step down to the triple-outlet GF004 when three points are enough, a double-outlet GF001 or GF002 for two, or the single-outlet GF009 when each position needs just one tap.
Why choose one four-outlet fitting instead of several single taps?
When four gas points belong at the same spot, one four-outlet fitting keeps things simpler: one deck hole instead of four, fewer penetrations in the worktop, and four gas points grouped in a single, tidy location. If your gas points are spread across separate positions, individual single taps like the GF009 may suit better. Tell us your layout, and we’ll advise.
Is the GF005 a good fit for teaching or high-traffic benches?
Yes. That’s where it fits best. Busy shared and teaching benches see more hands and more reaching across the worktop, so the press-and-turn safety on each of the four outlets helps prevent an accidental opening. Grouping four gas points in one fitting also keeps a crowded bench organized.
How does the slow-opening needle valve work?
The slow-opening action brings the gas up gradually when you open an outlet, rather than letting it surge, and the needle-valve design lets you fine-tune the flow for steady, controlled delivery. Combined with the press-and-turn safety, it gives you smooth control and protection against accidental release.
Which gases does the JH-GF005 work with?
It’s designed for standard laboratory gas service, but the appropriate connector and configuration depend on the specific gas. Rather than assume, we recommend confirming your gas type before ordering so we can match the correct configuration for safe, reliable operation. Share your gas type with our team, and we’ll confirm the right version.
What does the premium brass and CNC machining mean in actual use?
In practice, the higher-grade brass and CNC precision give you a fitting that seats and seals consistently, controls gas smoothly, and holds up longer under repeated daily use. It’s most noticeable when standardizing many fittings across a lab, where consistent sizing and finish keep installation and operation uniform bench to bench.
Can the handles be color-coded to identify gas?
Yes. The ergonomic PP knobs are available in custom colors, so you can color-code gas types across your lab for faster identification. If you’re standardizing multiple benches, let us know your color scheme, and we’ll match it.
What should I confirm before ordering?
Confirm four things: your deck hole size, available bench space for four outlets, your inlet connection, and your gas type. Checking these in advance helps ensure a secure, correctly matched four-outlet gas point. Share your setup, and we’ll confirm compatibility.
