Product Details

British made long reach radiator / pressure / expansion tank cap rated to 20 psi (20 lb). The pressure rating is stamped on the cap for quick identification. Supplied with a zinc coated cap case to help resist corrosion.

Spring length measurement: Spring length is measured from the large rubber seal to small rubber seal end of spring

Seal Type (Important):
This cap is supplied as a double sealed cap and is suitable for use on a sealed recovery system. In a sealed recovery system, the cap (double seal) allows coolant to flow to and from the recovery/expansion tank while maintaining the integrity of the cooling system.

Please note: Early caps sometimes only have one seal. If your existing cap is the single seal type (only one rubber seal – the small rubber at the end of the spring), the large rubber seal can be easily removed from this cap to match your setup.
