Silicone Rubber Gaskets Polysiloxane (VMQ)

Custom Gasket Mfg. is a recognized leading manufacturer of high quality silicone rubber gaskets, seals, and custom silicone products. 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 experience specializing in the manufacturing of precision die cut and molded silicone rubber gaskets and seals for a wide range of industries and applications. Silicone rubber is a high-performance elastomer with exceptional resistance to temperature extremes. Silicone molded and die cut gaskets remain functional within a temperature range of -67°F to +400°F, intermittent to +450°F. The low temperature flexibility of silicone is unmatched by any other elastomer. Silicone gaskets are often chosen due to their excellent resistance to chemicals, water, fire, fungal growth, ozone, heat and aging. Silicone has outstanding tensile strength, elongation, tear strength, and compression set. The versatility and long service life of silicone make it ideal for a wide variety of applications.

Die Cut Silicone Gaskets

Die Cut Silicone Gaskets

Custom Gasket Mfg. fabricates die cut silicone gaskets and water jet cut silicone gaskets in a wide variety of grades, thicknesses and hardness. The standard thickness of silicone rubber ranges from .010" to 1" thick. Silicone rubbers hardness (durometer) typically spans from 30 to 80 durometer, Shore A. We inventory a full spectrum of colors including red/orange, black, gray, blue, white, and translucent. Silicone rubber gaskets are available with or without acrylic or high temperature pressure sensitive adhesive (PSA) backing.

Custom Gasket Mfg. Available Silicone Rubber Grades

  • Fiberglass Reinforced Silicone
  • Coated Fabrics Silicone Sheet
  • Medical Grade Silicone (USP Class 6)
  • Extreme High Tear Silicone
  • Extreme High Temperature Silicone
  • Fabric Finish Silicone
  • Flame Retardant Silicone

Molded Silicone Gaskets

Silicone Molded Gaskets & Seals

Custom Gasket Mfg. specializes in the manufacturing of molded silicone gaskets and seals. Our custom molding capabilities include Compression Molding, Transfer Molding, Rubber Injection Molding, and Silicone Liquid Injection Molding (LIM). We commonly mold products using silicone, fluorosilicone, and FDA (food grade) silicone compounds which are available in color options red/orange, black, gray, blue, white, and translucent with custom color compounding available upon request. Silicone rubber molding compounds durometer (hardness) typically ranges from 25 to 80 durometer, Shore A. Silicone rubber molding tolerances are compliant with rubber molding industry standard RMA A2 Precision tolerances.


Conductive Silicone Gaskets

Custom Gasket Mfg. produces precision die cut conductive silicone gaskets and seals. Conductive Silicone is a unique composite of high quality silicone and conductive microscopic particles which are commonly used for electronic applications. These elastomers are filled with special conductive fillers such as; carbon, nickel, silicone plated glass, silver plated nickel, silver plated aluminum, silver plated copper, silver and reinforced silver plated copper to be either thermally or electrically conductive.

FDA (Food Grade) Silicone Gaskets and Seals

FDA (Food Grade) Silicone Gaskets and Seals

Custom Gasket Mfg. produces precision die cut and molded FDA (Food Grade) silicone rubber gaskets and seals. Our FDA approved silicone products are fabricated to meet all of your blueprint specifications and tolerance requirements in order to suit your particular application. All food grade silicone products we manufacture are FDA compliant and provide reliable service at temperatures ranging from -175°F to 482°F. Food Grade (FDA) silicone is odorless, tasteless, peroxide-free, and fungus resistant making it ideal in applications where food is present.


Fluorosilicone Gaskets and Seals (FVMQ)

Fluorosilicone Gaskets and Seals (FVMQ)

Custom Gasket Mfg. produces precision die cut and molded fluorosilicone rubber gaskets and seals. Similar to silicone, fluorosilicone (fluorinated silicone rubber) is intended for applications where there is contact with petroleum-based chemicals. However fluorosilicone can withstand more extreme temperatures and has superior chemical resistance properties to fuels, coolants and oils than standard silicone.
