9522-P Male BSPP Hex Head Plug with 60-Degree Seat
Description
The 9522-P Male BSPP Hex Head Plug with 60-Degree Seat series is designed for international hydraulic applications requiring British Standard Pipe Parallel (BSPP) threads with bonded seal face sealing. These forged plugs are commonly used to seal unused BSPP ports in hydraulic blocks, valves, manifolds, and equipment operating under high pressure.

BSPP threads feature a 55-degree thread flank angle, making them dimensionally different from NPTF threads. Because BSPP threads do not seal on the threads themselves, a bonded seal is required to achieve a reliable, leak-free connection. These plugs are fully compatible with the 9900 Bonded Seal series.
