Our EPDM rubber sealing rings are made of high elastic EPDM ethylene propylene diene rubber, precision one-step molding. Excellent waterproof, dustproof, weather and ozone resistance. Custom size, hardness, color and logo available, widely used in auto parts, hydraulic equipment, pipeline, engineering machinery sealing.
5 Core Selling Points
Premium EPDM Raw Material, Superior Weather Resistance Made of modified industrial EPDM rubber, outstanding anti-UV, anti-ozone, anti-aging performance. Stable elasticity under -40℃~120℃, no hardening, cracking or permanent deformation after long-term outdoor and high-temperature working. Far longer service life than ordinary recycled rubber.
Tight Sealing Performance, Multi-Layer Barrier Protection High elasticity and compression recovery rate, closely fit metal, plastic and pipeline joint surfaces. Effectively block water, dust, silt, air, splashing oil and coolant, prevent liquid leakage, gas seepage and internal parts corrosion.
Precision Integrated Molding, Smooth Flawless Surface One-piece precision mold forming without burrs, uniform thickness and consistent size. Smooth matte surface will not scratch matching parts, good compression resistance, no deformation after long-term extrusion.
Wide Compatibility & Stable Installation Suitable for flat flange, shaft, pipeline, gearbox, valve and motor sealing scenarios. High friction resistance, not easy to shift or fall off under pressure, vibration and frequent equipment operation, reduce maintenance frequency.
Full OEM Customization & Flexible Order Support Custom inner diameter, outer diameter, thickness, rubber hardness, color and silk screen brand logo. Fit automobiles, trucks, agricultural machinery, hydraulic equipment, water pipes and automation machines. Small trial orders & bulk wholesale acceptable, free samples for mass orders.
Product Advantage
Our EPDM rubber sealing gaskets & O-rings adopt precision one-piece injection molding technology, with uniform density and stable elastic recovery. Under continuous compression and vibration of equipment, the rubber ring can always closely fit the joint gap to form a fully sealed protective layer.
It can effectively isolate rainwater, dust, sediment, hydraulic oil, cooling liquid and air. Avoid liquid leakage, gas penetration, rust and abrasion of internal metal components, keep vehicle and mechanical equipment running stably, greatly extend the service life of valves, pipelines, gearboxes and hydraulic cylinders.
The surface is smooth without burrs, will not scratch the mating workpiece during assembly. Even under long-term vehicle bumping and equipment high-frequency operation, the sealing ring will not shift, pop out or lose sealing effect, stable and reliable for long-term use.
Material Performance
We adopt modified high-performance EPDM (Ethylene Propylene Diene Monomer) composite rubber formula:
Extreme temperature adaptability: Maintain soft elasticity from -40℃ low temperature to 120℃ high temperature, adapt to cold northern regions and high-temperature engine workshop environment.
Top weather resistance: EPDM material resists ozone, ultraviolet and natural aging, suitable for outdoor equipment, automobile exterior and open pipeline sealing, no cracking after years of exposure.
Good splash oil & water resistance: Resist splashing engine oil, brake fluid and rainwater, no swelling or softening under short-term liquid contact.
High compression resilience: After long-term squeezing, it can quickly rebound to the original shape, avoid permanent compression deformation leading to leakage.
Customized appearance service is supported: multiple color options, brand logo silk printing on the surface to meet aftermarket matching and brand wholesale demands.
