Interpump Ceramic Piston 20 × 50mm – W & WS Series Pump 47.0404.09

Product Overview

The Interpump 47.0404.09 Ceramic Piston is a genuine replacement piston designed for a range of Interpump 47 Series pressure washer pumps.

Manufactured from hard-wearing ceramic, this piston provides a smooth sealing surface and excellent resistance to heat, pressure and wear. Replacing a damaged, cracked or badly worn piston can help restore pump performance and prevent premature damage to the water seals.

This piston measures 20mm in diameter and 50mm long.

Please note: This listing is for one ceramic piston. Interpump pumps contain three pistons, so three will normally be required when replacing a complete set.
