Pysrych 2pcs 3/8" NPT Male to 3/8" BSPP Female Adapter Brass Pipe Fitting

just what i needed. where else would i go. great selection. just what you need and delivered to my door. at a great price

BSPP ( British Pipe Threads) require an oring to seal. Product arrived with no orings. The joint leaks. An incomplete product that does not serve its advertised purpose.

Nicely machined. Accurate to size. Be aware that a BSPP (British Standard Pipe Parallel) is not a taper thread, but is parallel. It has a different thread pitch and angle from imperial standards. Thread dope may or may not work. A washer or o-ring should be used. I used these adapters on a power washer unloader.

I used this adapter to connect a 1/4" BSP Iwata airbrush hose to the 1/4" NPT male connector on the outlet of my Badger 180-1 compressor. A few turns of teflon tape on both ends and a leak-free connection. Parts came faster than I expected. Bummer that you have to buy 2. Another chunk of brass rolling around in the bottom of the tool box.

Definitely not BSPP threads on the female end. I believe it is BSPT. BSPP are “parallel” the NPT male end of those adapters thread right into the female end. Not sure the Chinese know the difference. Didnt work for me.

if you have to replace the starter valve, otherwise known as the unloader valve, you will probably do so with a valve that has 1/4 NPT thread.....but the original starter valve has a different thread 1/4 BSPP. If you try to thread 1/4 NPT into 1/4 BSPP, you will cross thread the compressor

Good quality and value

Not npt

FYI, BSPP requires a gasket, and these do not have one.

Quality fitting for the price
