locking caps

Anybody familiar with these new Novent locking caps that the inspectors are now enforcing? I purchased the silver caps which are universal, and when I put them on they just keep spinning. I couldn't get them off without the tool, but I would think since they have a rubber gasket in it, and are suppose to be like a secondary seal, it would get to the point where it tightens up. Are these defective, or is this the way they work?



  • That'e the way they are

    That's the way they work.

    Although we would like to think that our service valves do not leak, the truth of the matter is that they do. The "backup seal" in the service port cap is not intended to be a major pressure holdback point in the system since major injuries could result if a technician were to remove the cap and have it shoot into his eye.
