Industrial Rubber Gasket

Industrial Rubber Gasket

Core Features

  • High-Grade Elastomeric Compounds: Manufactured from premium raw polymers including Nitrile (NBR), EPDM, Neoprene, and Viton (FKM) to meet specific industrial environment requirements.
  • Excellent Elastic Recovery: Features high resilience and “memory,” allowing the gasket to maintain a constant sealing force even under vibration, pressure surges, or mechanical shifting.
  • Low-Torque Sealing: The naturally soft and conformable nature of rubber allows for a gas-tight seal at low bolt loads, making it ideal for flat-face and non-metallic flanges.
  • Precision Durometer Control: Available in various hardness levels (typically 50 to 80 Shore A), ensuring the material is soft enough to seal but firm enough to resist extrusion.
  • Weather & Ozone Resistance: Specific compounds (like EPDM and Neoprene) are formulated to resist UV degradation and atmospheric aging, ensuring long-term outdoor reliability.
  • Anti-Friction Surface Finish: Available with cloth-inserted reinforcements or smooth finishes to facilitate easy installation and prevent the gasket from sticking to flange faces.

At Kriloha Ltd., we understand that while rubber gaskets are among the most common industrial seals, they are often the most misunderstood. A gasket that works perfectly for water may fail catastrophically in an oil line. The Kriloha Industrial Rubber Gasket line is engineered for “Application Specificity.” As a premier global supplier of industrial seals, Kriloha Gaskets utilizes advanced vulcanization techniques to ensure every gasket provides the mechanical “bite” required for your specific system.

The engineering of a Kriloha rubber seal focuses on Polymer Integrity. For water and steam service, we utilize EPDM, which offers unmatched resistance to heat and aging. For petroleum-based environments, our High-Nitrile (NBR) compounds prevent the swelling and softening that lead to blowouts. At Kriloha, we also offer Cloth-Inserted (CI) Rubber, where a layer of high-strength fabric is vulcanized between the rubber plies. This internal “skeleton” provides the dimensional stability needed for high-velocity flow and prevents the gasket from stretching under pressure.

Manufacturing these gaskets at Kriloha involves precision Die-Cutting and CNC Flash-Cutting. This ensures that every bolt hole and diameter is perfectly aligned with ASME, DIN, or JIS standards. We produce these in thicknesses from 1.0mm to 10.0mm. Whether you are sealing a massive irrigation pipe or a sensitive laboratory instrument, Kriloha Rubber Gaskets provide the elastic stamina and environmental resistance required for a reliable, leak-free joint. By choosing Kriloha Ltd., you are investing in a product that balances cost-effectiveness with professional-grade metallurgical and polymer engineering.

Primary Use Cases

  • Water & Wastewater Treatment: The standard for municipal water mains, filtration systems, and sewage transport lines.
  • Low-Pressure Plumbing: Sealing residential and commercial piping, valves, and pump housings.
  • HVAC & Ductwork: Providing airtight seals for large-scale ventilation systems and cooling towers.
  • Oil & Fuel Handling: Nitrile (NBR) variations are essential for sealing fuel lines, oil pans, and hydraulic reservoirs.
  • Chemical Processing: Viton (FKM) or EPDM gaskets are used for handling specialized acids, alkalis, and industrial solvents.

FAQs

How do I choose between EPDM and Nitrile?

    • EPDM is the best choice for water, steam, and outdoor weather resistance.
    • Nitrile (NBR) is mandatory for any system involving oils, fuels, or greases, as these fluids will cause EPDM to dissolve.What is the benefit of a “Full Face” gasket vs. a “Ring Type” gasket?

Full Face gaskets cover the entire flange surface and include bolt holes, providing better support for flat-face (non-raised) flanges. Ring gaskets sit only inside the bolt circle and are used for raised-face flanges to concentrate the bolt load.

Can I use rubber gaskets for high-pressure steam?

Standard rubber gaskets are generally limited to low-pressure steam and hot water. For high-pressure or superheated steam, Kriloha recommends our Flexible Graphite or Spiral Wound gaskets.

Why use “Cloth-Inserted” rubber?

The fabric reinforcement prevents the rubber from “creeping” or squeezing out of the flange under high bolt loads. It also adds significant tear resistance, making it ideal for high-vibration applications.

Are these gaskets safe for drinking water?

Yes, Kriloha provides specific potable water-grade EPDM that meets global safety standards for drinking water systems. Always specify “Potable Grade” when ordering for water treatment facilities.
