9042-24-20 1-1/2" Male BSPT x 1-1/4" Female NPTF - Steel

This fittings category is tailored to accommodate various threading standards, providing solutions for British Standard Pipe (BSP) threads, including both parallel (BSPP) and tapered (BSPT), as well as National Pipe Thread Fuel (NPTF) threads. BSP threads, with a consistent 55-degree flank angle, are engineered for reliable connections, distinguishing them from NPTF threads that have a 60-degree flank angle. This ensures compatibility and functionality across different systems.
