CO2 Cylinder Tank Leak Stopper - Permanent CGA320 Tank Valve Brass Washers (Qty 5)

Got a slow leak on your CO2 tank?

Don't waste gas.

These brass washers are designed to create a permanent seal on CGA320 tank valves.

You get a pack of 5 washers, so you have spares or can fix multiple tanks.

They're a simple, effective solution to stop leaks at the valve connection.

Just replace the old worn-out washer with one of these brass ones.

They're unbranded/generic but get the job done.

Important note: There's a California Prop 65 warning for cancer and reproductive harm.

Just be aware of that if you're in California.

Otherwise, these are a cheap and easy fix to stop your CO2 from leaking out.
