Crankcase Oil Pipe Union - AF

Product no.: 0246b A11/721-AF

This is the Union that fits into International and SOHC Manx crankcases for both Feed and Return. It allows for the standard 3/8" BSP SOHC Norton oil pipes to be connected. It is very close to original but is a modern item, and uses a larger spanner hex, requiring a UNF spanner. This is a cheaper alternative to the original brass union that I have made specially (Item no 0246), but as you only need to screw it in once this is not really an issue - item is still high quality and is cadmium plated. - Price is per each
