Custom Rubber Punched Gaskets
Extruded punched gaskets are fabricated with precision-punched holes to accommodate bolts and fasteners in the desired pattern. They are used to create reliable seals between two mating surfaces, blocking water & contaminants, dampening vibration, and, in select compounds, preventing electromagnetic interference (EMI).
Vip Rubber & Plastic manufactures punched gaskets using rubber sheet to custom dimensions and specifications in a wide range of rubber compounds, including EPDM, neoprene, silicone, Viton, and SBR. Contact our team of experts today for a custom gasket made to your requirements.
Punched Gaskets
Vip Rubber & Plastic is a leading manufacturer of punched gaskets and other rubber parts for demanding applications. Founded in 1961, we are one of the largest manufacturers of custom rubber products in the United States of America. We invite you to learn more and to contact us for the extruded rubber punched gaskets that you need.
Punched Gasket Specifications
We manufacture rubber punched gaskets in the following compounds:
- Butyl: Outstanding gas impermeability and vibration damping, ideal for airtight sealing
- Ecoprene: Versatile and environmentally conscious, offering broad application compatibility.
- EPDM: Excellent resistance to weathering, ozone, and UV exposure. Widely used in outdoor and water-sealing applications.
- Fluorosilicone: Combines temperature stability of silicone with resistance to fuel, oil, and solvents.
- FKM/Viton: Exceptional chemical and high-temperature resistance for demanding industrial environments.
- Natural Rubber: High tensile strength, resilience, and abrasion resistance for dynamic mechanical applications.
- Neoprene: Good balance of oil, weather, and flame resistance, reliable general-purpose sealing compound.
- Nitrile: Superior resistance to oils, fuels, and hydraulic fluids, common in automotive and industrial sealing.
- Silicone: Wide operating temperature range with excellent electrical insulation, suited for high-heat and food-grade applications.
- SBR/Buna: Cost-effective general-purpose compound with good abrasion resistance for low-stress sealing applications.
We can customize punched gaskets to your dimensional specifications, including:
- Height
- Width
- Length
- Diameter, outer diameter, hole diameter
- Hole pattern/placement
How to Select Punched Gaskets
The key to a high-performing, long-lasting punched gasket is finding the right compound for your application. Considerations include:
Industry Specification
Many industries require gaskets that conform to recognized standards such as ASTM, MIL-SPEC, Boeing BMS, or FDA guidelines. Identifying the applicable specification early in the design process ensures the correct compound, durometer, and dimensional tolerances are selected from the start.
Operating Environment & Service Temperatures
Depending on installation location, gaskets may be exposed to moisture, outdoor elements, pressure fluctuations, ozone, extreme temperatures, or mechanical stress. The operating environment is one of the primary drivers of compound selection, as different elastomers respond differently to environmental exposure.
Design Requirements
The physical configuration of the gasket, including outer diameter, thickness, hole diameter, hole pattern, and profile cross-section, must be defined to ensure a proper fit within the assembly. Custom tooling allows for precise hole placement and bolt patterns to match your mating surfaces.
Chemical and Ultraviolet Light Resistance
Exposure to oils, fuels, hydraulic fluids, solvents, acids, or prolonged UV radiation will degrade compounds not formulated for resistance. Nitrile is well-suited to oil and fuel environments, FKM/Viton handles aggressive chemicals and high heat, and EPDM provides reliable UV and ozone resistance for outdoor applications.
Installation Technique
How a gasket is installed affects its required durometer and dimensional tolerances. A bolt-compressed flange gasket requires sufficient compliance to conform under load, while an adhesive-mounted or press-fit gasket may need tighter dimensional control. Specifying the installation method helps ensure the gasket performs as intended over its full service life.
Our team can guide your order from the initial quote through manufacturing, using a variety of materials and highly trained technical staff, making us a trusted manufacturer of rubber gaskets for industrial applications.
