Perfect Fitting
I bought these because I needed to convert a BPS thread to NPT threads. It is hard to tell the difference in pitch of the threads and I have read quite a bit on the differences to realize they are different and may cause leaks due to the small differences in the pitch diameter of the threads. These worked perfect for my application on a BPS 1/2-in faucet I bought overseas for use with other US fittings in a place that I did not want any leaks. After a couple of months of being installed, no leaks and I don't expect any. These worked perfect for my application.

Right concept / wrong thread pitch
These look & feel sturdy & machined thick to handle psi... unfortunately, I returned these due to change of plans in my project design... thank you

Needed for recirculating pump
The recirculating pump I bought on this site had BSP fittings (so annoying) so I needed something to convert it to NPT. This did the trick perfectly. Just be careful how tight you tighten down on the rubber gaskets with your fitting to make sure they get a good seal and use plenty of teflon tape/pipe dope.

British to USA thread adapter
This "G" thread mismatch with NPT standard threads can be a nasty little surprise. Of course the Brits have a different standard ... go figure. Well, these fix the mismatch. Get 'em.

This fitting is not NPT male it's 3/4 BSP female to 3/4 BSP male useless to fit to a NPT fitting, very misleading

bueno, medidas exactas, solo hay que reforzar con cinta teflón, es muy difícil encontrar este tipo de adaptadores en México, gracias.

This is meant to be 2 Pack G 3/4 ( BSP ) Female Thread to US 3/4 NPT Male Thread Pipe Fitting. That is, the male is meant to be US 3/4 NPT and the female 3/4 BSP. I bought a 2 pack. If it was a BSP to NPT adapter, they would get about 1 1/2 threads in then begin to cross-thread. Yet, the adapter screwed all the way down to rubber gasket. When I went to attach the supposed 3/4 BSP Female end to a 3/4 BSP male fitting - it got about 1 1/2 threads then jammed. It's not 3/4 BSP female. It's pretty well much that simple.

Tried using to adapt US device to AUS garden hose outlet. Didn't work due to wrong thread size on adaptor than what was advertised
