Lister A & B Junior Valve Cap Joints B91 (Pair)

High quality valve cap sealing joints made just like the originals, with a rolled copper fire ring around high temp gasket material. These gaskets fit under the threaded brass plugs that sit over the valves on both tank cooled, and hopper cooled Lister A & B Junior engines.

Not suitable for the early single flywheel models which have a much smaller seal.

Sold in Pairs.
