BSP Hydraulic Adaptors
BSP(British Standard Pipe) Hydraulic Adaptors is designed with a Whitworth thread or BSPP thread ISO 228-1 G standard, 60 degree cone connector with or without o-ring seal by metal to metal or and O-ring. BSP adapters are manufactured in accordance with BS 5200 and ISO 8434-6 standards, The 60 degree cone seat is designed for sealing with BSP hose swivel connections, they are intended for the connection of tubes and hose fittings to ports in accordance with ISO 6149-1 and ISO 1179-1/DIN 3852. BSP adaptors are used as hose adapter fittings on equipment in Europe, UK, Scandinavia, Netherlands, Spain and Italy.

Installing the wrong type or size of a BSP adaptor can either make pipe and hose connections impossible or threaten your entire hydraulic system. To avoid that, choose the same fittings as what you’re replacing or double-check that the new adaptors are compatible with the ports and assemblies.
For starters, decide whether you need male, female, tapered, or threaded connectors. As a manufacturer of BSP adaptors, Fitsch has all these options across parallel, straight, T-shape, elbow, and easy-to-maintain BSPP types.
Additionally, you should:
Accurately measure the ports, pipes, and hoses to be attached and check the outer diameters of BSP adaptors to pick the right fit.
Count threads and take a closer look at the cone angle to prevent ill-fitting connections down the road.
Explore what standards apply to your hydraulic system and inspect adaptors for compliance.
See whether your connections can accommodate O-rings or additional seals, which some BSP adaptors come with.

If you want to buy a BSP adaptor of a particular type, you can directly inquire about the connector in question. We’ll share more technical details upon request.
