FAQ
This cap features a 3-1/8 inch diameter with 11 threads per inch (3-1/8"-11), which is a standard size for many high-pressure gas cylinders.
Generally, no. Acetylene cylinders often use different neck ring sizes or coarse threads. This cap is designed for standard high-pressure cylinders like oxygen, argon, or nitrogen that use the 3-1/8"-11 ring.
Cylinder caps protect the valve from shearing off if the cylinder falls. A sheared valve can turn a pressurized cylinder into a dangerous projectile. They are also required by DOT regulations during transport.
It is made of heavy-duty steel to provide maximum impact protection.
It fits most standard industrial size oxygen cylinders (like sizes K, T, S) that have a threaded neck ring. It does not fit small medical cylinders or cylinders without neck rings.
No, the regulator must be removed before the cap can be installed. The cap is for storage and transport only.
This is likely a manufacturer-specific part code or reference to the fine thread specification, but the critical dimension is the 3-1/8"-11 thread.
Yes, when properly installed on a compatible cylinder, it meets DOT requirements for valve protection during transport.
