9035S-04-06-PORT 1/4" Male BSPP (with Washer and O-ring) x 3/8" Female NPTF-PORT

BSPP Fittings with Bonded Seals utilize British Standard Pipe threads, also known for their 55-degree thread flank angle, differentiating them from NPTF threads that have a 60-degree angle. Bonded seals are required for secure sealing when using male BSPP threads in ports or blocks, making them suitable for high-pressure systems.
