This is the oil delivery or return union that was fitted to the crankcases of most pre 1950 OHV and SV crankcases (as well as breathers on some of the SOHC models).  These look just as per the Norton items and are CNC machined by us in brass (as most originals were)

These Red Fibre Washers are a smaller diameter than 'normal' 1/4" BSP washers - but then pre-threaded by us - so they are a good fit on those Norton fittings that used 1/4" BSP thread, but have a groove behind the thread - e.g. Norton pre-48 Oil Sump Plugs and some breather union fittings.  See detail listing for more information.  This listing is for a bag of 5 washers
