9028-04 Countersunk Hollow Hex Plug with Seal 1/4" BSPP

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. These fittings are compatible with our 9500 Bonded Seal series.
