Brand: Setrab Oil Coolers

If your BSP fitting or port does not have a sealing flare or O-ring chamfer, you should use a Dowty Sealing Washer to seal the connection at the face of the female port. A Dowty washer is comprised of a flanged rubber insert bonded to the inside of a thick aluminum washer. The rubber insert is molded to stand slightly proud of each side of the washer to ensure a good seal. Sold individually.

If your male fitting has a concave flare at the end and the female has a matching convex flare, no sealing washer should be used. If the female port has a chamfer, use one of our BSP O-Ring Seals (Part No. 3243-Size).

Note: BSP nomenclature can be confusing because the nominal size refers to the inside diameter of the pipe, not the outside diameter of the threads. 1/2 BSP has parallel threads measuring 0.81" OD x 14 threads per inch. If you are not sure what size you need, check in our Threaded Fitting Guide.

We also carry Dowty Sealing Washers in several more BSP sizes under Part No. 3240-Size.
