The green and silver pieces fell apart when first used. Luckily I had a press to put the two pieces together. Never had this problem again (after 100+ uses). The threads are threaded so it loses pressure very slowly. Finally, the inner diameter is very small, so your pressure tester will not snap, but will still seal airtight. In general it does what I need, but not quite right. It feels like it's fake.
