Premium Rubber Products for Sealing Applications

Discover professional-grade rubber sealing solutions engineered for demanding industrial, automotive, plumbing, and manufacturing environments. Our comprehensive selection of sealing products includes gaskets, O-rings, seals, weatherstripping, and custom-cut rubber sheets designed to prevent leaks, contain pressure, and protect against environmental elements.

Why Choose Our Rubber Sealing Products?

Industrial sealing applications require materials that can withstand extreme temperatures, chemical exposure, pressure variations, and continuous compression. Our rubber sealing products are manufactured from high-performance elastomers including Neoprene, EPDM, Nitrile (Buna-N), Silicone, and Viton, each offering unique properties for specific sealing challenges.

  • Oil & Chemical Resistance: Nitrile and Viton seals resist petroleum products, hydraulic fluids, and aggressive chemicals
  • Weather & Ozone Protection: EPDM gaskets provide superior outdoor durability and UV resistance
  • Temperature Extremes: Silicone seals maintain flexibility from -60°F to 450°F
  • Water & Steam Applications: High-grade elastomer compounds prevent moisture ingress
  • Custom Fabrication: Available in sheets, rolls, and die-cut shapes for precise specifications

Frequently Asked Questions

What rubber material is best for oil sealing?

Nitrile (Buna-N) and Viton are the best choices for oil sealing applications. Nitrile provides excellent resistance to petroleum-based oils, fuels, and hydraulic fluids at an economical price point. Viton offers superior chemical resistance and higher temperature capability (up to 400°F), making it ideal for demanding automotive and industrial applications where exposure to aggressive chemicals and extreme heat is common.

How do I choose the right gasket thickness?

Gasket thickness selection depends on surface irregularities, flange stiffness, and compression requirements. For smooth machined surfaces, use 1/16″ (1.6mm) gaskets. Rough cast surfaces need 1/8″ (3.2mm) or thicker to fill imperfections. High-pressure applications require thinner, denser gaskets with metal reinforcement, while low-pressure static seals benefit from softer, thicker materials that conform easily under light bolt loads.

Can I use rubber seals for high-temperature applications?

Yes, but material selection is critical. Silicone seals handle -60°F to 450°F continuously, making them suitable for ovens, steam lines, and hot water applications. Viton performs exceptionally up to 400°F with chemical resistance. Standard EPDM and Neoprene are limited to approximately 250°F. For extreme temperatures above 500°F, consider specialized fluoroelastomers or switch to metal gaskets with graphite or PTFE fillers.

What’s the difference between static and dynamic seals?

Static seals (gaskets, O-rings in grooves) prevent leakage between stationary surfaces like pipe flanges or equipment housings. They require compression but no lubrication. Dynamic seals (shaft seals, piston seals, wipers) operate on moving surfaces and need low-friction materials with excellent wear resistance. Dynamic applications typically use Nitrile, Polyurethane, or PTFE-based compounds with lubrication compatibility, while static seals prioritize compression set resistance and chemical compatibility.

How long do rubber seals typically last?

Service life varies dramatically based on material, environment, and application. EPDM outdoor weatherstripping lasts 10-20 years with proper installation. Nitrile O-rings in hydraulic systems typically provide 2-5 years under normal operating conditions. High-temperature silicone seals in automotive applications may last 100,000+ miles. Factors reducing lifespan include improper installation, chemical incompatibility, over-compression, UV exposure, and operating beyond temperature limits. Preventive replacement schedules are recommended for critical sealing applications.
