Correct (and as per original) 1/4" BSP 'One Way Valve' - as fitted to all Norton singles, including all SOHC, OHV and SV models - this item screwing into the recess just above the drive side main bearings, allowing the engine to breathe correctly. July 2023: Now back in Stock 

These are the unions that screw into the crankcase behind the timing chamber - it is the smaller 1/4" BSP side that screws into the crankcase, the larger side is 3/8" BSP and takes the distinctive large oil pipes fitted to Norton Internationals. 

This is a faithful reproduction of the straight through union fitted to SOHC (and DOHC) cambox's for connecting the cambox oil feed pipe (fitted at top of crankcase and cambox), but also used as a front crankcase breather on many Inters and magnesium racing engines.  Finally it is also fitted as a breather union on the bevel chamber of magnesium racing crankcases behind the inner timing cover (while Inter crankcases instead employ a pressure telltale unit).  Copied from an original pre-war item

This is modern replacement for the straight thru breather used on Norton crankcases and timing cases - but uses AF Hex (not Whitworth) - if you are not worried about originality!

This is the oil tank union fitted to many International\Manx oil tanks with the larger 3\8" BSP fitting on both sides (crankcase unions were smaller on the crankcase side). Please note - these do not have gauze filters fitted, which the 'Feed' side union would have had originally (I might make some of these in the future). Gauze can easily be added in by soft soldering.

These are (vulcanised) red fibre washers to fit the 1/8" BSP thread on the Norton Oilers (Item 0570 and 0571).  If you are purchasing the oilers - then they already come supplied with the red fibre washer, but these can be used if you want additional spacing (to ensure you can adjust them to tighten into just the right position without stressing the thread), or if you have original oilers or other 1/8" BSP connectors that need new washers.  As always, these washers come from a high quality specialist supplier and are 1mm thick.  They come supplied in a pack of 4

- Modern Reproduction of the classic 3" butterfly filler cap as fitted to Norton International and pre-featherbed Manx Norton petrol tanks. Note: These filler caps as supplied to me do not have the cork sealing washer - which I think is pretty poor - so I have had a press tool made for making these from the correct gasket cork, I then fit them before sending out (if buying from elsewhere you may want to check they come with these washers - I suspect they will not!).
