70 Shore A NBR O-Ring Seals for Specified Service Conditions
One Stop service
Send the O-ring size designation or drawing, target 70 Shore A hardness tolerance, fluid details and operating conditions.
Application
Application of the rubber o ring:
NBR (nitrile rubber) O-rings for applications reviewed against the actual fluid, temperature, pressure and gland design.
O-rings seal within a specified gland using the selected ring dimensions and compound. For this 70 Shore A NBR product, confirm inside diameter, cross-section, gland dimensions, squeeze and installation clearance. Temperature suitability depends on the exact NBR formulation, fluid and exposure duration; hardness alone does not establish a high-temperature rating. FKM, silicone and EPDM are separate compound options and require separate selection.
Product Description
SHQN supplies NBR O-ring seals with a target hardness of 70 Shore A in specified standard or drawing-based dimensions. Provide the exact size designation and required tolerances for quotation.
Specify inside diameter and cross-section rather than relying on a broad catalog size range. Confirm production feasibility for the individual ring and compound.
This listing concerns NBR. FKM, EPDM and silicone alternatives require their own compound and service specifications.
