Aram Flat Sealing Ring – Seals the One-Way Valve in the Piston Head
A small ring with a big job: it seals the valve in the piston head, keeping pressure where it belongs.
The original flat sealing ring that seals the one-way valve in the piston head of the Aram.
What the sealing ring does
The flat sealing ring seals the one-way valve in the piston head of the Aram. That keeps the pressure in the system while you pull, instead of it escaping. Seals are wear parts – a fresh ring restores a clean seal.
An original spare part keeps your Aram in shape for a long time. Our opinion is one among many.
