This cap protects the threads and keeps the tank valve clean. It is not intended to seal the tank.

Printed @ 0.2 mm layer it takes approximately 24 minutes to print. It has a 1"-20 UNEF Class 2B thread and fits every propane and MAPP gas bottle (cylinder) I have tested.

*** Tips are gladly accepted and much appreciated. ***
