FAQ
Questions Buyers Ask
1/2" NPT or 1/2" BSPP - which thread?
NPT is US standard, BSPP is the parallel pipe thread common in Europe/Asia. They are not compatible - a BSPP male will not seal in an NPT female. Match the hose fitting exactly.
What pressure can a 1/2" coupler handle?
Typically 200-350 bar depending on profile (flat-face tends higher) and material. Confirm the data sheet for the exact model.
