When standard rubber gaskets won’t hold up under heavy compression or mechanical fastening, a cloth inserted rubber gasket is often the right solution. At CGIM LLC, we manufacture cloth inserted rubber gaskets that combine the sealing properties of rubber with the reinforcement of woven fabric, giving your flanged connections the stability they need to perform under demanding conditions.
What Is a Cloth Inserted Rubber Gasket?
A cloth inserted rubber gasket is made by embedding one or more plies of woven fabric between layers of rubber. Common fabrics include nylon, polyester, cotton, and fiberglass, and each ply is typically added per 1/16″ of material thickness. The fabric reduces side-to-side creep under load, increases tensile strength, and improves dimensional stability in applications where bolted flanges would otherwise cause the gasket to deform over time.
Cloth Inserted Rubber Gasket Materials
Selecting the right base elastomer is critical. Our cloth inserted rubber gasket materials include:
- Neoprene is a great choice for environments involving hot or cold water, gases, and moderate petroleum exposure. It performs reliably in meters, control devices, regulators, pumps, and diaphragms.
- SBR (Styrene-Butadiene Rubber) offers abrasion resistance and works well with air, steam, and hydraulic fluids. It is a cost-effective option for general industrial sealing where oil exposure is minimal.
- Nitrile (Buna-N) is the preferred choice for applications requiring resistance to oil, fuel, and petroleum-based hydraulic fluids. Fuel tank gaskets, diesel systems, and aviation fuel environments all benefit from nitrile’s chemical resistance.
- EPDM handles weather exposure, ozone, and temperature extremes. It holds up well in outdoor installations and systems that cycle between hot and cold conditions.
Cloth Inserted Silicone Gaskets
For applications that demand performance across wide temperature ranges, we also fabricate cloth inserted silicone gaskets. Silicone maintains its flexibility from cryogenic conditions up through sustained high heat, and it resists weathering and oil deterioration in ways that many other elastomers cannot match. These properties make a custom cloth inserted silicone gasket a strong fit for furnace seals, oven door gaskets, and other equipment exposed to temperature extremes.
As with our rubber options, the fabric reinforcement in a silicone gasket reduces creep and improves dimensional stability under compression. Cloth inserted silicone gasket cutting is performed to your exact specifications, whether from a drawing, a sample, or a standard flange dimension. Fiberglass is a common fabric choice for silicone applications, as it complements the material’s heat resistance.
Custom Cloth Inserted Rubber Gasket Fabrication
Every application has its own requirements for size, shape, material, and tolerance. CGIM LLC manufactures each custom cloth inserted rubber gasket to your specifications. We work from your prints, samples, or purchase order details to produce gaskets that fit your equipment precisely.
Our cloth inserted rubber gasket cutting capabilities include die cutting, waterjet cutting, and CNC machining, allowing us to handle orders ranging from a single prototype to high-volume production runs. If you have a unique sealing challenge but no finalized design, our team can help you select the right combination of elastomer and fabric reinforcement for your operating conditions.

Frequently Asked Questions About Cloth Inserted Rubber Gaskets
How does cloth insertion affect gasket performance compared to plain rubber?
The embedded fabric plies significantly increase tensile strength, in some cases up to 1,400 PSI, depending on the number of layers. The reinforcement also prevents the gasket from tearing during mechanical fastening, a common failure point with plain rubber in bolted flange assemblies.
What durometer ratings are available for cloth inserted rubber gaskets?
Cloth inserted rubber gaskets are generally available in 60 and 80 Shore A durometer. The right hardness depends on your flange surface condition, bolt load, and the media being sealed. Our team can help you determine which rating suits your application.
What is your lead time for custom cloth inserted rubber gaskets?
Lead times vary based on material availability, order size, and complexity. We maintain a large inventory of rubber and gasket sheet stock, which allows us to turn many orders around quickly. Contact us with your specifications for a timeline estimate.
