Burajet Chamber rings 8032/AU

Burajet retainer rings are molded HPU (hydrolysis-resistant polyurethane) or FKM (fluorocarbon rubber) rings with sealing lip which are produced to match the shaft and gland housing. They efficiently retain the Burajet injectable compound packings, thus reducing product contamination. The compensation for radial shaft movements is also better than with braided packings.

Notes:

Easy to handle during installation. To make it easier to fit into assembled systems, the profile ring can be cut through at one point and then glued back together using cyanoacrylate adhesive. The rings are manufactured to fit the shaft and gland housing diameters. An exact measurement is needed (accurate to 0.1 mm) in order to produce the lip seals with the correct dimensions.
