Product Overview
Tapered silicone hole grommets can provide a gradual change in the rubber profile around a cable entry. The taper should face the direction required by the assembly and have enough room to follow the cable without folding against nearby structure. Its shape does not remove the need to match the retaining seat and cable passage accurately.
Check the panel thickness, opening profile, and finished cable covering. Include the space for the cable bend beyond the sleeve and the route used during installation. A larger connector may need to be fitted after the grommet reaches its intended position rather than forced through the working passage.
Seat the retained portion first, then arrange the sleeve and cable without residual twist. Inspect the transition after nearby cable supports are tightened. During maintenance, look for wear where the taper meets the more rigid panel seat. Repeated rubbing at that point can indicate that the bend begins too close to the opening and needs more clearance in the surrounding assembly.
- 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: Include the space for the cable bend beyond the sleeve and the route used during installation.
- Custom profile & fit
- Check the panel thickness, opening profile, and finished cable covering.
- Assembly considerations
- A larger connector may need to be fitted after the grommet reaches its intended position rather than forced through the working passage.
- Design check
- Inspect the transition after nearby cable supports are tightened.
Photos illustrate structure or material only. The shape does not remove the need to match the retaining seat and cable passage accurately. ETOL directly manufactures custom-shaped silicone and rubber parts to your requirements.

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.
