Characteristics and performance

The Hallite 37 single-lipped, metal-cased wiper is designed to press fit into open groove housings for light and medium-duty applications. The precision trimmed nitrile (NBR) wiping element is securely bonded to a metal case treated to inhibit rust. The proportions of the NBR wiping lip follow the side movement of the rod to clear away the deposited dirt.

For heavier duty applications, Hallite would recommend using the Hallite 860 single-lipped, metal-cased polyurethane wiper.

Product details

The Hallite 37 is offered in a range of sizes suitable for ISO 6195 Type B housings.
