Electrical Enclosure Gaskets
Custom-Fabricated Sealing Solutions for Electrical Cabinets, Control Panels, and Outdoor Enclosures.
Reliable Sealing Solutions for Electrical Enclosures
Electrical enclosure gaskets protect sensitive equipment from dust, moisture, temperature extremes, vibration, and electromagnetic interference. SRP manufactures precision-cut gaskets that help you maintain NEMA, IP, and UL 50 ratings while keeping your equipment safe, dry, and reliable.
Choosing the Right Gasket for Your Enclosure
Selecting the best gasket depends on the environment, enclosure type, and performance goals. SRP helps you evaluate:
- Gasket Function – Do you need the gasket to seal out liquids, solids or air, mitigate shock or vibration, block EMI or RFI?
- Gasket Size – Are there limitations on gasket format (die cut vs. stripping)?
- Gap Spacing – What is the thickness range of the gap?
- Temperature – What high and low temperatures will the material reach and for how long?
- UV/Ozone Resistance – Will the material be directly exposed to the elements?
- Flame Rating – Does your application include requirements like UL-V0, UL-HBF or FMVSS-302?
- Chemical Resistance – Will the material be in contact with chemicals or fluids?
- Outgassing – Could material outgassing be detrimental to components?
- Color – Will a particular color improve ease of assembly or help with future inspections?
- Cost and Performance – Does your application require a premium product?
Materials for Electrical Enclosure Gaskets
SRP offers a wide range of high-performance materials engineered for sealing, insulation, and protection in electrical enclosures. Each material provides unique advantages depending on environmental and performance requirements.PORON® Polyurethane Foam
PORON microcellular urethane provides consistent compression and recovery, excellent dimensional stability, and resistance to stress relaxation. Ideal for tight-tolerance enclosures, it delivers long-term sealing and vibration damping performance for electronics, lighting, and control panels where space and reliability are critical.BISCO® Silicone Foam
BISCO silicone foam offers outstanding environmental resistance, long-term compression recovery, and temperature stability from –55°C to 200°C. It’s ideal for outdoor or high-heat applications, providing durable sealing against dust, water, and vibration in EV chargers, telecom enclosures, and harsh industrial environments.Closed-Cell Sponge Rubber (EPDM, Neoprene, Nitrile blends)
These resilient materials deliver reliable sealing against air, water, and dust. EPDM resists weathering and UV; neoprene balances oil and ozone resistance; and nitrile blends add fuel resistance. Perfect for outdoor electrical housings, junction boxes, and control panels exposed to changing environments.Closed-Cell Foam (PVC / NBR / EPDM blends)
Closed-cell foams combine compressibility, flexibility, and environmental protection. They provide effective sealing against moisture, dust, and light chemicals while offering cushioning for sensitive components. Ideal for cost-effective indoor and light-duty enclosures requiring durable, consistent performance and ease of installation.Silicone Rubber (Solid & Sponge)
Silicone rubber withstands extreme temperatures and maintains flexibility across a broad operating range. It offers excellent electrical insulation, UV and ozone resistance, and long-term durability. Commonly used in aerospace, transportation, and high-performance electrical enclosures requiring stability under continuous heat exposure.Conductive / EMI-Shielding Silicones
Conductive silicones combine environmental sealing with EMI/RFI shielding performance. Filled with conductive particles such as nickel-graphite or silver-aluminum, these gaskets ensure electromagnetic compatibility while maintaining environmental integrity. Ideal for defense, communications, and instrumentation enclosures where both sealing and electrical conductivity are critical.
