Hot-selling molded rubber grommet/protection NBR cable ring grommet

An NBR cable ring grommet cushions the cable passage through a panel. The nitrile compound should suit the actual contact environment, while the ring's retained dimensions match the opening and wall. When a used liner is stretched or worn, the panel itself is the more useful reference for a replacement fit.

Measure the mounting hole and the cable jacket separately, and examine the cut edge for a local burr. A new grommet should seat without being held in place by cable tension. Custom size, color and marking details can distinguish the selected part in an assembly. After routing, check the inner contact at the cable's normal resting position. If the previous liner was worn on one side, inspect the bend and nearest support for a persistent pull. Correct that route before using the replacement. During service, renew a cut lip instead of pressing the same damaged area back into its groove, where it can leave the hard panel edge exposed.

Material options

Custom NBR formulation; tailor the geometry and color to the required interface and exposure.

Hardness range

30–90 Shore A for rubber. Assess the grade against this fit requirement: The nitrile compound should suit the actual contact environment, while the ring's retained dimensions match the opening and wall.
