Molded silicone (VMQ) grommets for cable, wire and panel pass-throughs in equipment that runs hot, needs an FDA/NSF-compliant material, or sits outdoors under UV and ozone exposure. Built by injection or compression molding to your panel opening, cable OD and hardness spec.
Silicone earns the higher material cost when one of these applies:
Silicone compounds typically rated from −60°C to around +200°C (high-temperature grades higher), a wider working range than NBR or neoprene tolerate without hardening or cracking.
FDA and NSF compliant grades are available for food-contact or clean-assembly specs that general-purpose rubber can't satisfy.
Better ozone and weathering stability than NBR or neoprene in continuously lit or outdoor enclosures.
Low compression set holds sealing force through thermal cycling better than harder general-purpose compounds.
If the application runs at moderate temperature with no compliance requirement, EPDM Rubber Grommets cover that range at a lower material cost.
Down to ±0.02mm on critical dimensions (general molding capability, confirmed per part after drawing review)
Plus fully custom profiles
Set to the installation force your assembly needs
Natural, FDA-white, or custom color for model/line identification
From your 2D drawing, 3D model, or physical sample
For hole-plug applications — see Rubber Blind Grommets & Hole Plugs for that variant
For cable-bundle or harness-specific profiles, see Rubber Cable Grommets for Panel Openings. For a splash- or submersion-rated grommet where heat and FDA compliance aren't the driver, see Rubber Grommets.
Injection and compression molding draw on 3,500+ existing tool profiles, with new tooling built from your drawing and functional prototypes available in 3–5 business days. Production runs under IATF 16949:2016 and ISO13485:2016 certification, with FDA and NSF compliant material grades and UL-certified compounds available for electrical applications.

Rubber components help seal control panels and electrical enclosures against dust, moisture, vibration and cable movement. See rubber parts for electrical equipment.
Heat-resistant rubber parts are used around appliance housings exposed to elevated temperatures, repeated cycling and vibration.
Sealing components for medical equipment can be molded from suitable compounds for clean-assembly and application-specific requirements. See medical rubber parts.
Rubber parts for food-processing equipment can be selected according to temperature, cleaning conditions, chemical exposure and food-contact requirements.
Weather-resistant sealing components help protect outdoor and marine electronics from rain, humidity, salt exposure and temperature changes.
