Our company’s reputation for excellence has been built on our ability to provide our valued customers with the most effective designing, engineering and manufacturing solutions to meet their most demanding applications. Our main objective is to continuously exceed our customer’s expectations by providing them with high performance gaskets and sealing products, competitive pricing, on-time delivery and exceptional customer service. Custom Gasket Mfg. maintains a modern manufacturing facility along with knowledgeable, technically-oriented professionals enabling us to consistently meet all of your blueprint specifications and tolerance requirements.
Custom Gasket Mfg. has over forty years of experience specializing in the manufacturing of precision custom rubber gaskets and seals for a wide range of industries and applications. A rubber gasket is a sealing product used to fill the space between two or more mating surfaces generally to prevent leakage (of air, chemicals, gases, or liquids) from or into the joined objects while under compression. Rubber gaskets are used for forming tight seals between two components. Custom Gasket Mfg. uses a variety of production and material options to solve even the most challenging sealing applications. We manufacture custom rubber gaskets and seals in a wide range of rubber materials (and compounds) including: Neoprene®, Silicone, EPDM, Viton®(Fluorocarbon), Nitrile (Buna-N), SBR (Red Rubber), Butyl, Natural (Gum) Rubber, Polyurethane, Fluorosilicone, Hypalon®, Santoprene®, Hydrogenated Nitrile, Epichlorhydrin, Cloth-Inserted Rubber, Conductive Rubber, Thermoplastic Rubber, and FDA Approved Rubber. Custom Gasket Mfg. offers standard commercial grade materials and specification grade materials that meet FDA (Food Grade) and ASTM specifications. For the reason that different elastomers offer different mechanical and chemical properties, we offer custom compounds to meet specific high performance applications.
Types Of Rubber Gaskets
Custom Gasket Mfg. recognizes the importance of material selection for manufacturing processes; die cutting, rubber molding, rubber extruding, water jet cutting. We guarantee that we will produce the most appropriate rubber gasket to meet your unique application. Custom Gasket Mfg. provides customers with an extensive range of rubber elastomers to choose from. The most common types of rubber gaskets we supply are listed below. Our knowledgeable customer service team will gladly assist you in determining which material will perform best in your application.
Neoprene® is the trade name for Chloroprene which was the first synthetic rubber. Neoprene rubber is an extremely versatile synthetic rubber used for harsh environment applications due to its moderate resistance to oil and petroleum base solvents. Neoprene exhibits good resistance to ozone, sunlight, aging, and other weather elements.

Silicone rubber is a high-performance elastomer with exceptional high and low temperature properties. Silicone molded and die cut gaskets can withstand within a temperature range of -75° F to +500° F. The low temperature flexibility of silicone is unmatched by any other elastomer. Read More »
Fluorocarbon elastomer Viton® (a trade name of the DuPont™ Corporation) is a high performance rubber compound known for its outstanding resistance to high temperature and broad range of chemicals. Viton® rubber’s permeability and compression set are excellent. Viton® displays good resistance to oils and solvents, aggressive fuels, and concentrated acids. Read More »
EPDM Gasket (EPDM Seal) Ethylene Propylene Diene Monomer (EPDM, EP, EPT)
EPDM rubber is a copolymer of ethylene and propylene. EPDM rubber is one of the most popular, versatile materials available. EPDM is known for its excellent ozone, sunlight, and heat resistance and exceptionally good weather aging properties. Its distinctive ability to stabilize color and resist harsh weather conditions makes it and ideal choice for outdoor applications. Read More »
Nitrile rubber, also known as Buna-N, is the most widely used elastomer for seals and gaskets. Its properties provide superior resistance to petroleum-based fluids, hydraulic fluids, gasoline, alkalis and acids. Nitrile is the polymer of choice for applications requiring oil and solvent resistance. Read More »
SBR rubber is a synthetic polymer, commonly known as “Red Rubber”. SBR is a copolymer of styrene and butadiene and has properties similar to Natural Rubber. SBR is highly resilient and commonly used because it is cost-efficient and has the ability to deform to uneven flange edges. SBR (red rubber) exhibits excellent impact-strength, high tensile strength, abrasion resistance, heat resistance, and sustains flexibility at lower temperatures. Read More »
Butyl rubber is a copolymer of isobutylene and isoprene. Butyl rubber has exceptionally low gas, air, and moisture permeability. It offers excellent weathering properties and has outstanding resistance to sunlight, ozone, heat aging, oxygen, abrasion and tearing. Butyl is used in many applications requiring airtight rubber. Butyl rubber has excellent dielectric properties and is resistant to acids and alkalis.

Natural (Gum) rubber is an elastic material that was originally derived from milky sap or latex of some tropical plants (specifically the rubber tree). Natural rubber, also referred to as “gum rubber”, has many positive characteristics. It has superior resilience, high resistance to tear and abrasion, tensile strength, good compression set, and molding properties. Natural rubber is soft and displays good flexing qualities at low temperatures. Read More »
Polyurethane Gasket Polyester urethane / Polyetherurethane (AU/EU)
Polyurethane is the toughest and most abrasion-resistant of all elastomeric materials. Polyurethane is a unique versatile material that provides the elasticity of rubber combined with the durability and strength of metal. Polyurethane consistently outperforms plastic, rubber and steel in its capacity to resist harsh environmental factors such as abrasion, heat, oil, acid, solvents and many chemicals.

Cloth-Inserted (CI) Rubber Gasket
Cloth-inserted Rubber (SBR, Neoprene, EPDM, Buna-N) is a rubber sheet with a polyester, nylon, cotton, or fiberglass fabric impregnated in the rubber. Cloth reinforcement improves dimensional stability in flanged gasket applications with high compression loads. The fabric helps to reduce tearing when fastened. The materials construction typically includes one ply of fabric for each 1/16" thickness.
Hypalon® Gasket Chlorosulfinated Polyethylene (CSM)
Hypalon® is one of the most weather-resistant elastomers. It demonstrates almost complete resistance to UV/ozone and will not degrade with long-term sunlight exposure. It has excellent resistance to abrasion, oil, most chemicals and acids, it has good dielectric strength, and low moisture absorption. Its normal temperature range is between -50°F to 275°F. Hypalon® is ideal for the industrial, construction, automotive and petrochemical industries.
