    Hills pump piston seals

    Does anyone know the specification (size and material) of the piston seal for a Hills Mk2 pump ? And maybe a supplier.

    I think that £13.50 from Hills themselves is an excessive price to charge for three small o-rings, so would like to source some elsewhere.

    Thanks in advance.

    Personally I have found Hills prices to be extremely competitive and their customer service second to none. These aren't ordinary 'o' rings but the heart of the pump and will last years. Regards, Geoff.

    Dogfight, thank you for your advice.

    I have not found this seal to be durable and "last for years", despite proper use (avoiding overheating) and lubrication.

    The fact that Hills sell them in packs of three suggests that it is regarded as a consumable item.

    If anybody else can tell me the size and material specification I would be most grateful.
