GasStop RV Propane Automatic Shut-Off | GSUSA1 | POL | UL/CSA

Protect your RV from catastrophic propane leaks with the GasStop GSUSA1 Automatic Propane Shut-Off Device (POL Connection). The only 100% emergency shut-off device for RV propane systems — mechanically and completely shuts down propane flow in the event of a major leak, plus a built-in gauge for minor leak testing across your entire propane network.

Automatic Emergency Shut-Off

GasStop automatically, mechanically, and completely shuts off propane flow in the event of a major leak — defined as propane flow of more than 70 SCFH (75,000 BTU/hr).

Major leaks can happen due to:

• Loose fittings
• Tire blowouts that puncture propane lines
• Critters/rodents eating through propane lines
• Old propane lines that rupture under pressure
• Other propane system failures

GasStop will NOT shut off propane flow during normal appliance operation — only triggers on catastrophic leak flow rates.

Built-In Propane Gauge

Integrated pressure gauge shows when propane is running low — always know what's left in the tank at a glance.

Minor Leak Testing (3-5 Minutes)

Beyond the emergency major-leak function, GasStop enables a simple 3-5 minute test for minor propane leaks anywhere in your propane network — catches slow leaks that would otherwise go undetected. See included instructions for test procedure.
