Product Overview

Silicone Rubber Oval Shaped Grommets need space beyond the panel opening for their outer lips. This range provides edge protection for elongated cable passages, with separate groove and exterior dimensions that help establish that space during panel layout. Checking only the cutout can leave too little room next to a rib, screw or adjacent opening.

For the listed 40 by 80 mm groove, the outside outline is 50 by 90 mm. That exterior should lie on an unobstructed seating area. The smaller 36 by 76 mm interior is the opening available for cables once the grommet is installed. Each set of dimensions serves a different part of the layout.

Several groove widths are offered across the family. Choose according to the finished panel thickness, including relevant surface layers at the edge. Do not use pressure from a neighboring cover to make an unsuitable flange lie flat.

Before the cable route is finalized, trial the grommet alongside nearby hardware. Confirm that screws can still be fitted without catching the rubber and that enclosure closure leaves the lip undisturbed. If clearance is insufficient, revise the surrounding arrangement or select a suitable profile before wiring makes access more difficult.

Material options
Custom silicone or rubber formulation, with dimensions and color adapted to the mating component.
Hardness range
Silicone: 20–80 Shore A; rubber: 30–90 Shore A. Assess the grade against this fit requirement: Do not use pressure from a neighboring cover to make an unsuitable flange lie flat.
Custom profile & fit
Choose according to the finished panel thickness, including relevant surface layers at the edge.
Assembly considerations
The smaller 36 by 76 mm interior is the opening available for cables once the grommet is installed.
Design check
Checking only the cutout can leave too little room next to a rib, screw or adjacent opening.

Ordering this custom component

Can the shape be adjusted to my mating parts?

Yes. Show the receiving opening, contact surfaces and clearance limits. We can review the dimensions and retaining features around the intended fit.

Which details should be agreed before tooling?

Agree the critical dimensions, material, hardness, visible surfaces and sample requirements. Explain how the part is installed and which interfaces control its function.

Can a sample help define the replacement?

A sample can help explain the structure. Compare it with the assembly because wear, swelling or compression may have changed its original dimensions.

How is the quotation for this part determined?

The material, part geometry, tooling, quantity and finishing affect the quotation. Include the intended batch size and delivery destination when describing your requirements.
