BSP Male to AN or NPT Male Adapter

View Catalog Page in PDF format

Use these fittings to adapt your plumbing to female BSP (British Standard Pipe) ports. We offer both NPT to BSP adapters as well as AN to BSP adapters to cover a wide variety of situations. All of these adapters have male threads at each end. Sold individually.

British threaded female ports often have a chamfer for an O-ring to seal the face of the port. If the port face is not chamfered, an aluminum washer or a Dowty seal is generally used to seal the fitting.

Note: BSP and NPT nomenclature can be confusing because the nominal size refers to the inside diameter of the pipe, not the outside diameter of the threads. If you are not sure what size you need, check in our Threaded Fitting Guide.

Very nice adapter fittings BSP to NPT threads. A bit expensive: over $30 for just two fittings and domestic shipping, but they got the job done.

This was the only place I could find BSP adapters to plug my stock fuel tank and LP pump into my after market fuel lines and fittings. So happy to do the direct conversion!

Just what you need for 2JZ NA-T Oil Feed

I got this fitting to use in conjunction with an IS300 union bolt to provide an oil feed. No worries about tapping the union bolt to 1/8" NPT or trying to thread in a 1/8" NPT fitting and risking a leak.

Needed this BSP fitting as gearbox manufactured in England. Certainly not available at the local hardware store. Fantastic quality & worked great!

Just right

If you need to go from a US standard to a British standard thread this works. I needed it to go from a standard air fitting to a airbrush line. I knew it was not a NPT or metric and took a chance on the BSP. Yes, it works great. I was very impressed with how fast Pegasus got the part to me. Two days with standard shipping. It must have left the same day I ordered it.
