Q1: What is a rubber grommet?
A: A rubber grommet, also known as cable grommet or wire grommet, is a molded rubber fitting inserted into panel holes. It protects cables, wires and hoses from sharp edge cuts, provides strain relief, insulation, dustproof, splash sealing and vibration damping.
Q2: What material options do you offer for rubber grommets?
A: We have EPDM, NBR, silicone, FKM, neoprene and natural rubber. EPDM is the best choice for outdoor, UV, ozone and hot water conditions, not suitable for oil & fuel.
Q3: What is the temperature range of EPDM rubber grommet?
A: Standard sulfur-cured EPDM: -40°C ~ +120°C continuous use, intermittent peak up to 150°C. Peroxide cured EPDM can reach -40°C ~ +150°C continuously.
Q4: What shapes of grommets can you produce?
A: Round, oval, square, rectangular, double-sided, split, single-hole, multi-hole and irregular custom shapes. We make products according to your drawings or samples.
Q5: What hardness is available?
A: Hardness range: 40 ~ 90 Shore A. Common selections: 50A, 60A, 70A, 80A. 70 Shore A is widely used for general cable protection.
Q6: Where are rubber grommets applied?
A: Mainly for automotive wire harness, EV firewall, electrical cabinets, junction boxes, solar inverters, charging piles, marine wiring, HVAC, outdoor lighting and industrial machinery.
Q7: Is EPDM grommet oil resistant?
A: No. EPDM has poor resistance to mineral oil, gasoline, diesel and hydrocarbon solvents. Choose NBR grommet for oil environments, FKM for high temp oil and chemicals.
Q8: Can you make custom color and size rubber grommets?
A: Yes. We support custom size, thickness, hole layout, color and hardness. OEM & ODM molded service is available.
Q9: What certifications can you provide?
A: RoHS, REACH, IATF16949, ISO9001 documents can be supplied upon request.
Q10: How to install rubber grommet?
A: It is snap-in installation. Stretch the grommet slightly and press it into the pre-drilled panel hole, then pass cables or hoses through the inner bore.
