Reliable Sealing Performance Buna-N HNBR Elastomer Lip Ring With Brass Backing
Product Photo
Product Specification
Buna-N and HNBR lip rings with brass backing are specified as matched replacement components for the identified hammer union. Confirm the rubber profile and brass ring inside diameter, outside diameter and thickness against the union manufacturer drawing. Provide the figure number and nominal line size; the brass backing and elastomer must match the mating recess.
For a backed-ring order, specify Buna-N/NBR or HNBR, Shore A hardness and fluid-service conditions separately. Colour does not identify the compound. Unbacked and stainless-backed catalogue versions require their own confirmed configuration and should not be substituted solely by nominal size. Operating pressure belongs to the complete rated union assembly.
