Red Fibre 'Sized' 3/8" BSP Banjo and Oil Fitting Washers - Pair

Red Fibre washer that fits over most 3/8" BSP Banjo fittings, as well as 3/8" BSP Oil Tank fittings. 

Price is for a pair of washers.

Just like trying to obtain good quality 1/4BSP fibre washers - it is actually very difficult to find good quality red fibre washers in 3/8" BSP size - as most are slightly sloppy, and therefore do not seal very well, or crush when tightened.  This is also important on most 3/8" oil pipe unions - as they normally have a groove behind the thread - therefore if the washer goes on easily - it will be all sloppy when it gets to the groove.

These washers come from a top quality (and expensive!) red fibre washer manufacturer - and are a good tight/'sized' fit on 3/8" fittings.  They will firmly press on to most 3/8" type banjo fittings - as per the one in the photograph, and will also fit onto 3/8" BSP thread unions, by gently but firmly rotating them along the thread - but once fitted, they are then a good fit where the groove is. 

Being from a good quality manufacturer, they are also made from a harder material than some other cheap fibre washers to be found on Ebay!
