This auction is for a pair (2) of oil tank filter sealing washers for the BSA range of Unit Singles.

The original part number is 29-7971, originally fibre washers but these are self-centring sealing washers that can be reused if you are careful.  I use these on my own '68 BSA B25 Starfire to good effect: they fit well and don't leak.

7/8" (21mm) ID
1 1/4" (31.8mm) OD
1/10" (2.5mm) THICK


N.B. ONLY the seals washers are included in this sale and NOT any other part or assembly.

If you have ANY questions then please just ask.  I always leave feedback once I know the goods have arrived.
