Stainless Steel BSP Hydraulic Adapters
High-Quality British Standard Pipe Hydraulic Fittings
What Are BSP Hydraulic Adapters?
Stainless steel BSP hydraulic adapters are precision-machined fittings designed to connect hydraulic components using British Standard Pipe threads. Available in BSPP (parallel) and BSPT (tapered) thread types, these adapters provide reliable sealing performance in medium- and high-pressure hydraulic systems.
BSPP connections typically seal through bonded washers, O-rings, or metal sealing faces, while BSPT threads create sealing through controlled thread interference. Manufactured from corrosion-resistant 304 and 316 stainless steel, BSP hydraulic adapters are widely used in hydraulic machinery, marine systems, oil & gas equipment, and industrial fluid transfer applications.
Designed to meet ISO 228, ISO 7-1, and DIN standards, stainless steel BSP adapters ensure dimensional accuracy, thread compatibility, and long-term reliability in demanding environments.

Frequently Asked Questions
Common questions about BSP adapters and hydraulic fittings
What is the difference between BSPP and BSPT threads?
BSPP (British Standard Pipe Parallel) features a parallel thread and requires sealing via an O-ring, bonded seal, or gasket. BSPT (British Standard Pipe Tapered) uses tapered threads that seal through thread interference when tightened. Selecting the correct type depends on your system design and sealing requirement.
Are BSP and NPT threads compatible?
No. BSP and NPT threads have different thread angles and pitch profiles.
- BSP: 55° thread angle
- NPT: 60° thread angle
They are not directly interchangeable and should not be mixed in hydraulic systems.
What pressure ratings do stainless steel BSP adapters support?
Pressure ratings vary depending on size, thread type, and design configuration. Most stainless steel BSP hydraulic adapters support working pressures up to 6,000 PSI. For detailed ratings, please contact our technical team.
