BSPP (British Standard Pipe Parallel) refers to a common thread standard widely used across hydraulic applications, including reservoir accessories and strainers. Components with BSPP threads ensure a parallel, non-tapered fit, crucial for achieving reliable, leak-proof connections in fluid power systems. This standard is particularly prevalent in the UK and Europe, providing compatibility and interchangeability for various hydraulic fittings and adapters. Understanding BSPP specifications is key to maintaining efficient and safe hydraulic operations.
