Features
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.
Advantages
Easy to handle during installation.
