Industrial Gaskets — Reliable Sealing Solutions for Every Industry

What / Why — Gaskets are engineered sealing elements that prevent leakage between two mating surfaces. Choosing the right gasket reduces downtime, ensures safety and extends equipment life.

Executive Summary

Our industrial gasket portfolio covers materials and constructions for high-performance sealing across temperature, pressure and chemical environments. This page helps procurement, engineers and maintenance teams quickly evaluate options and download technical data.

What is an Industrial Gasket?

Gaskets are mechanical seals used to fill the space between two or more mating surfaces. They are available in sheets, rings, and custom-cut parts and are selected based on media compatibility, temperature, pressure, and flange finish.
Gasket Classification

By Material

  • Graphite (flexible graphite sheets)
  • PTFE (pure, filled)
  • Rubber (NBR, EPDM, Viton®)
  • Non-Asbestos Composites
  • Metallic & Spiral-Wound

By Structure

  • Sheet gaskets
  • Spiral-wound gaskets
  • Ring-type joints (RTJ)
  • Compressed fiber gaskets

By Application

  • Petrochemical & Refining
  • Power Generation (steam)
  • Food & Pharma (sanitary PTFE)
  • Water & Sewage
  • Automotive & HVAC

Selection Guide — How to Choose the Right Gasket

  1. Identify media (steam, oil, corrosive chemicals, potable water).
  2. Temperature & pressure — confirm max operating T and P and transient conditions.
  3. Flange type & finish — flat face, raised face, RTJ.
  4. Regulatory & hygiene — food-grade PTFE, FDA/USP where required.
  5. Compression & recovery — important for dynamic or thermal cycling applications.

Technical Parameters & Common Dimensions

Below are sample technical parameters often used for pre-selection.
Material Temp Range (°C) Max Pressure (bar) Typical Thickness (mm) Key Applications
Graphite (flexible) -200 to 450 ≤ 250 0.5 / 1.0 / 2.0 Steam, high-temp services
PTFE (pure) -200 to 260 ≤ 100 0.5 / 1.5 / 3.0 Chemical, food, pharma
Rubber (EPDM) -40 to 150 ≤ 16 1.5 / 3.0 Water, HVAC
Spiral-wound (metal + filler) -200 to 550 ≤ 400 ASME standard High pressure / temp

Common Sheet Sizes

Sheet Size (mm) Typical Thicknesses (mm) Usual Use
1000 x 1000 0.5, 1.0, 2.0 Cut gaskets / small flanges
1500 x 1500 1.0, 2.0, 3.0 Large flange gaskets
2000 x 1000 1.5, 3.0 Custom-cut & fabrications

Installation, Tightening & Maintenance Guide

Proper installation and bolt tightening significantly increase gasket life:
  1. Clean flange faces — remove old gasket residue and debris.
  2. Inspect flange flatness and alignment.
  3. Use proper bolt torque pattern — incremental cross pattern tightening.
  4. Re-torque after initial heating/cool cycle when recommended.
  5. Routine inspection schedule for critical services.

Application Industries & Case Studies

Representative industries where our gaskets are used:
  • Petrochemical & Oil & Gas — high-temp steam and corrosive service
  • Power — boiler feed, turbine auxiliaries
  • Food & Beverage — sanitary PTFE gaskets
  • Water Treatment — long-term sealing in potable water systems

Case Study — Refinery Heat Exchanger

Problem: Repeated leakage at high-temperature exchangers. Solution: Replaced compressed fiber with flexible graphite sheet + spiral-wound gaskets on critical flanges. Result: Zero leaks in 18 months.

Performance Comparison & Material Selection Matrix

Property Graphite PTFE Rubber Spiral-wound
Chemical resistance Excellent (oxidizing caution) Excellent Good Excellent (metal selection dependent)
Temp range Very wide Wide Moderate Very wide
Compressibility High Moderate High Low (metal)
Suitable pressure High Low-Mid Low Very High

Common Failures & Troubleshooting

Leak at flange after installation
Causes: Insufficient torque, uneven flange, wrong gasket material. Check torque sequence and flange faces.
Gasket extrusion or blowout
Causes: Overpressure, too thin material, incorrect gasket type. Use reinforced or thicker gasket and verify design pressure.
Rapid aging / cracking
Causes: Chemical attack, temperature above material limits. Replace with compatible material and review operating conditions.
