You are purchasing 3 black (with carbon for dry lubrication) EPDM FDA certified machined piston cup seals for the Vectis made here in Auckland, New Zealand
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
