9028-20 Countersunk Plug with Seal, 1-1/4" BSPP - Steel Hydraulic Adapters

BSPP fittings with bonded seals use British Standard Pipe threads, characterized by a 55-degree thread flank angle, unlike the 60-degree angle of NPTF threads. Bonded seals are essential for secure sealing when using male BSPP threads in ports or blocks, making them ideal for high-pressure systems. These fittings are compatible with our 9500 Bonded Seal series.
