Very Well Made
Great little solid brass check valve. Not sure exactly what the cracking pressure is but I'm guessing around 10 because it's pretty tight. A little too tight for use on a RV pump but perfect for street pressure in a house.

Not NPT threads
Threads are not NPT (not tapered) so it will not seal even with sealant on the threads.

JUNK!!!
I've done plumbing jobs for 30+ years. No matter how much you tighten the fitting it leaks at the threads. Teflon or pipe dope doesn't help. Save $$$ and don't buy this junk!!
