Rubber Gaskets for Sealing, Damping & Fluid Resistance

Rubber gaskets are sealing components manufactured from various elastomer materials, either by die-cutting from rubber sheet or by compression molding into the desired shape. They are widely used in automotive, plumbing, chemical, food processing and general industrial applications where flexibility, resilience and fluid resistance are required.

Rubber gaskets are available in a wide range of polymers: natural rubber (NR) for high elasticity and tear strength; nitrile rubber (NBR) for excellent oil and fuel resistance; neoprene (CR) for weather, ozone and moderate oil resistance; EPDM for outstanding weather, ozone and water/steam resistance; silicone for wide temperature range and flexibility; fluoroelastomer (FKM/Viton) for superior chemical and high-temperature resistance; and SBR for general-purpose economy. Custom dimensions and non-standard shapes can be produced according to drawings or samples.

We supply rubber gaskets for overseas distributors, industrial buyers, gasket fabricators, maintenance companies and OEM customers, with different polymers, hardness grades, dimensions, thicknesses and packaging available according to specification.

Multiple Elastomer Materials NR, NBR, CR, EPDM, Silicone, FKM, SBR and other specialty rubber compounds.
Wide Hardness Range From soft 20 Shore A to hard 90+ Shore A, customizable to application needs.
Custom Dimensions Available in any inner/outer diameter and thickness to match your flange or equipment.
Application-Specific Grades Oil-resistant, food-grade, flame-retardant, anti-static and high-temperature grades.

02

Hardness & Thickness

Specify Shore A hardness and gasket thickness. Thicker gaskets and softer grades compensate for rough or uneven surfaces; harder grades provide better load bearing.

03

Operating Conditions

Define temperature range, chemical exposure, UV/ozone exposure, pressure and mechanical load to select the optimal compound.

PROCESS / 03

Curing & Inspection

Gaskets are vulcanized to develop final mechanical properties, then inspected for dimensions, hardness, tensile strength and surface defects.

PROCESS / 04
