Interpump KIT139 – Seal retainer kit 18mm is a pump ring and seal-support repair kit for the matching pressure-washer component. Order by the exact reference, KIT139, rather than appearance alone.
Seal retainers and support rings must match the pump’s original assembly. Use the parts drawing to identify where this kit belongs, and inspect the adjoining seals and piston surfaces during the repair.

Choose the right repair
Match the kit reference to the exploded parts drawing for your exact pump or valve. A similar model name or piston diameter alone does not establish compatibility. Send Idro the identification plate and part number if you need a hand checking the match.
