A BSPT‑F x BSPT‑F female hex coupling is a precision-engineered pipe fitting designed to connect two female BSPT-threaded ports of the same size. It features female BSPT threads on both ends and a hexagonal body for easy tightening or removal with a wrench, ensuring a secure, leak-resistant connection in piping or instrumentation systems.
These couplings are widely used in hydraulic, pneumatic, instrumentation, and fluid systems across industries such as oil and gas, chemical processing, manufacturing, and power generation. When installed with thread sealant or PTFE tape, the BSPT tapered threads provide a reliable and high-pressure resistant connection suitable for demanding applications.
