Professional manufacturer of different sizes silicone rubber gaskets

Silicone rubber gaskets in different sizes should each follow the mating joint rather than being treated as simple scaled copies. A larger opening may use different fastener spacing or a less rigid cover, changing how the gasket is compressed. Its thickness, sealing width, and locating features need attention at each size.

Compare the full outline with the finished assembly, including corners, bolt holes, and any passages that must remain clear. Select the silicone formulation around the actual medium, operating temperature, and cleaning process. Longer unsupported regions of the joint should be checked for even closure rather than compensated for with unnecessary rubber thickness.

Install the gasket without stretching its outline to meet the last locating point. Bring the mating faces together evenly and inspect for displaced edges. During maintenance, compare the contact pattern around the whole part, not just near the fasteners. If one region remains less compressed, investigate the adjoining face and fastening arrangement before changing to another gasket size or section that may disturb the rest of the joint.

Material options

Silicone. Custom formulation and color for the intended contact conditions.

Hardness selection

Silicone: 20–80 Shore A. A larger opening may use different fastener spacing or a less rigid cover, changing how the gasket is compressed.

Custom dimensions

If one region remains less compressed, investigate the adjoining face and fastening arrangement before changing to another gasket size or section that may disturb the rest of the joint.

Fit & assembly

Longer unsupported regions of the joint should be checked for even closure rather than compensated for with unnecessary rubber thickness.

Use & inspection

During maintenance, compare the contact pattern around the whole part, not just near the fasteners.
