Rubber Grommet Applications
Protect / Seal / Insulate
Electronics · Machinery · Furniture
Rubber grommets protect wires and cables from sharp panel edges. Sealing performance depends on the grommet profile and its fit with the panel and cable. Tell us your required protection level and test conditions. Common applications include electronics, electrical appliances, machinery, sports equipment, furniture and lighting.
There are many types of rubber materials used for producing rubber grommets. Common materials include Nitrile rubber, Natural rubber, Neoprene, Silicone, and Fluoro rubber. The hardness of these grommets typically ranges from 30 to 60 Shore A. Customers can customize rubber grommets with different materials to suit the specific needs of their products.
General Shapes of
Rubber Grommets
Depending on the different applications of rubber grommets and the shape of the holes on the board, rubber grommets are commonly used in the following shapes:
Material Options for Rubber Grommets
NBR
NBR (Nitrile)
Oil-resistant applications
Material details
NBR (Nitrile) grommets are used in applications requiring oil resistance. Select the compound for the oil, operating conditions and required properties. Antistatic performance must be specified and verified for the selected grade.
CR
CR (Neoprene)
Weather & ozone resistance
Material details
Neoprene rubber grommets are used where heat, ozone and weather resistance are required. For outdoor or flame-retardant applications, confirm the selected compound and the required test performance.
EPDM
EPDM Rubber
Weather & ozone resistance
Material details
EPDM rubber grommets are suitable for outdoor applications requiring resistance to weathering, ozone and water. They are generally unsuitable for petroleum oils and fuels. Confirm the compound for the intended service conditions.
FKM
FKM (Fluorocarbon)
Chemical & heat resistance
Material details
FKM rubber grommets are used for demanding chemical and temperature conditions. Chemical compatibility and continuous operating temperature depend on the compound and application; review the relevant material data before selection.
VMQ
VMQ (Silicone)
Color & material versatility
Material details
Silicone grommets offer temperature flexibility and electrical insulation. Typical service range: -60 to 200°C. Higher short-term temperatures require a specially qualified compound. Water, steam and chemical exposure have separate limits.
Physical Properties of Rubber Grommets
Compare temperature ranges and key physical properties.
| Material | Temperature range | Tensile strength | Elongation at break | Rebound resilience | Tear strength | Abrasion resistance |
|---|---|---|---|---|---|---|
| NR (Natural Rubber) | -40 to 70 °C (-40 to 158 °F) | Excellent | Excellent | Excellent | Favorable | Favorable |
| NBR (Nitrile) | -30 to 100 °C (-22 to 212 °F) | Good | Good | Good | Favorable | Favorable |
| FKM (Fluorocarbon) | -20 to 200 °C (-4 to 392 °F) | Good | Fair | Fair | Limited | Favorable |
| VMQ (Silicone) | -60 to 200 °C (-76 to 392 °F) | Fair | Compound-dependent | Fair | Not recommended | Not recommended |
| CR (Neoprene) | -35 to 90 °C (-31 to 194 °F) | Good | Good | Good | Favorable | Favorable |
| EPDM Rubber | -45 to 130 °C (-49 to 266 °F) | Fair | Fair | Fair | Limited | Favorable |
| SBR (Styrene-Butadiene) | -40 to 100 °C (-40 to 212 °F) | Good | Excellent | Good | Limited | Favorable |
Temperature ranges describe typical general-purpose service; fluid-specific limits may be lower. Special short-term capabilities are not continuous-service ratings. Physical ratings describe material families; hardness, tensile strength, elongation at break and compression set require compound-specific testing.
