1/4" Diameter Oil Pipe BSP Fittings - For Douglas 2 3/4 hp Models and other Flat Tank Motorcycles

This Sub Listing is for:

7/16"  x 20tpi Stainless Steel Union Nut and 1/4" bore brass Ferrule to fit Oil Drip Feed Pipe

7/16" x 20 threads per inch (20tpi) nut (CNC from Stainless Steel to original 0.5" AF Hex profile - hex milled from solid bar)  and tapered ferrule to fit 0.5" pipe.  These are the correct thread to fit the tank mounted Drip Feed Oil Feed Unit unions, as fitted to Douglas models from approximately 1917 to the late 1920's - as shown in the accompanyning photos.  This listing is for one union nut and ferrule.  Two of these are required per Drip Feed unit.

Although the photographs show this drip feed regulator fitted to the petrol tank of my  1919/20 Douglas 2 3/4hp model, I believe similar drip feed units were also fitted to other makes of motorcycles.  If unsure on  

Note: these fittings are more expensive than commercially avaiable BSP fittings as we have specially written CNC programs to mill the hex from stainless steel round bar to the correct imperial hex size as original, with similar profile and chamfer to original nuts
