DESCRIPTION
Our MMC-U is a metal cased wiper designed to press-fit into open groove housings. This wiper comprises a precisely trimmed polyurethane wiping element which is securely bonded to a metal case treated with a rust inhibitor. Capable of operating in dirty conditions, the proportions of the polyurethane wiping lip allow it to follow the side movement of the rod and to clear away heavily deposited dirt.
Suitable for light, medium and heavy duty applications, the wiper has been designed to provide ease of installation and offers excellent durability in service.
The MMC-U offers a wide range of sizes suitable for standard Metric housings.
