Select a product to estimate shipping.Precision-cut threads bite tight on the first turn—zero gas loss, zero worries.
All-brass 6.6 ft hose included—unbox, connect, done. No extra trip to the store, just more time on the job.
Built-in safety valve automatically vents if outlet pressure exceeds 600 psi—no manual intervention, full job-site protection.
Ergonomic T-handle gives one-hand, fingertip control—smooth, exact pressure tweaks without the strain.
For safety, when the low-pressure gauge reads 600 PSI or approaches it, the regulator’s relief valve will automatically open—you’ll hear gas escape, but this is intentional venting, not a leak.
Ready to work right out of the box?
Absolutely! We throw in a 6.6 ft all-brass nitrogen hose—competitors don’t. Bolt it onto any CGA-580 cylinder and you’re pressurizing lines in 60 seconds.
I hear a hiss at 600 PSI—leak?
That’s the Auto-Relief safety valve saving your skin. It opens automatically at 600 PSI to vent excess gas; the sound means it’s protecting you, not leaking.
Can I really adjust pressure with one hand?
Yes. The oversized T-Tune handle gives fingertip control even with gloves, letting you dial 0–800 PSI smoothly while your other hand holds the torch.
Will the body handle a 4 000 PSI cylinder surge?
No sweat. High-density brass construction + SealThread precision threads are burst-tested to 6 000 PSI—zero deformation, zero leaks, decade-long life.
Only for HVAC, or more?
One regulator, four jobs—chemical purging, welding shield gas, lab inerting, pressure testing. Buy once, replace four specialty regulators, and save bench space.
