Our BSP blanking caps are engineered to seal and protect unused male BSP-threaded ports in hydraulic, pneumatic, and fluid power systems. Whether used during system maintenance, modification, or long-term storage, these caps prevent the ingress of dirt, moisture, and contaminants, while also containing residual pressure to avoid leaks. Manufactured from high-quality materials such as mild steel, stainless steel, or brass, they provide excellent durability, corrosion resistance, and long service life—even in demanding industrial environments.

Each cap features precision-machined BSPP (parallel) threads for a tight, secure fit and leak-free performance. Ideal for use in workshops, agricultural machinery, manufacturing equipment, or construction hydraulics, BSP blanking caps are an essential component for protecting critical systems and maintaining safe, efficient operations. Available in a wide range of sizes to suit various applications.
