You are purchasing 3 grade 'A' white EPDM machined piston seals for the Vectis
These seals are despatched from New Zealand by air mail in a bubble envelope, so allow up to 3 weeks for them to arrive
Think of these as water lubricated seals. Do not pull the lever arm unless the boiler is pressurised, otherwise there is no water in the group to lubricate the seals
