What is gasket material and why does it matter?
What are the most common gasket material types and where are they used?
- PTFE (Teflon) gasket material: excellent chemical resistance and broad temperature tolerance; often used for highly aggressive chemicals and clean processes. Common in chemical processing, pharmaceutical, and food-grade applications when compatible with media and flange design.
- Silicone gasket material: good thermal stability and flexibility, broad temperature range, ideal for food-grade and medical devices; excellent for low-pressure sealing and sanitary systems.
- EPDM gasket material: superb water, steam, and weather resistance; widely used in HVAC, water systems, and hot-water lines; not compatible with petroleum-based fluids.
- Nitrile (Buna-N) gasket material: strong resistance to oils, fuels, and some solvents; common in automotive, drivetrain, and hydraulic applications; moderate temperature capability.
- Neoprene gasket material: good balance of oil and weather resistance; used in general purpose seals, pneumatic systems, and some chemical services.
- FKM/Viton (fluorocarbon) gasket material: excellent chemical and heat resistance; used in chemical processing, aerospace, and oil & gas sectors; suitable for aggressive media at high temperatures.
- Graphite and graphitized gasket material: high temperature and temperature cycling capability; often employed in high-pressure steam, refinery, and heat-exchanger applications; used as standalone sheets or laminated with elastomer.
- PTFE-graphite laminated gaskets: combine chemical resistance of PTFE with improved seating and strength from graphite; common in high-purity and high-temperature services.
- Cork, rubber, and composite gasket sheets: versatile, lower-cost options for general purpose sealing, equipment maintenance, and flange repairs; often used in non-critical or legacy systems.
How do I choose gasket material based on temperature and chemical exposure?
- Identify the media: acids, bases, solvents, hydrocarbons, water/steam, or food-grade media. Check chemical compatibility charts for each material.
- Determine the maximum and average operating temperature, including potential spikes. Choose materials with adequate temperature tolerance and low creep under your load.
- Assess pressure and flange design: higher pressure and more severe flange conditions may require materials with higher compression resistance or laminated structures (e.g., graphite or PTFE-graphite).
- Consider long-term reliability: some elastomers exhibit compression set or are less stable with certain media. For aggressive chemicals or hot environments, fluorinated elastomers (FKM/Viton) or PTFE-based options often perform best.
- Factor in installation and maintenance: some materials are easier to machine, cut, or preform into rings or gaskets for quick replacements.
Are there food-grade or pharmaceutical-grade gasket materials available?
- FDA compliance for direct contact with food and beverages
- USP Class VI or GMP-grade elastomers for medical and pharmaceutical equipment
- EU and other regional food-contact approvals for materials used in processing and packaging lines
- Non-toxicity, low extractables, and cleanability, especially in clean rooms and hygienic systems
- Sanitary designs for gasket sheets and pre-cut gaskets used in dairy, beverage, and pharmaceutical processing
How do I decide gasket thickness and sheet material for a given flange?
- Thicker gaskets (e.g., 1.5–3 mm) can accommodate flange imperfections and provide higher seating force, but may require more compression and can increase bolt loads.
- Thinner gaskets (e.g., 0.5–1 mm) are suitable for well-machined flanges and moderate pressures, reducing bolt load but needing precise surface finish.
- Sheet material should be selected for media compatibility, temperature, and mechanical requirements. For high-temperature or high-pressure services, graphite, PTFE, or elastomer-impregnated laminates are common choices.
- Hardness (Shore A) and compressibility affect seating and leak prevention. Softer elastomers seat more easily but may exhibit higher compression set under sustained load.
- Always consult a gasket material compatibility chart and consider the flange standards (ANSI/ASME, DIN, JIS) to ensure the chosen thickness and material are suitable for the gasket design.
How do I install and maintain gasket materials to maximize life and seal integrity?
- Inspect ingredients and surfaces: ensure flange faces are clean, flat, and free of burrs, oil, and debris. Use appropriate surface finishes to minimize leakage points.
- Cut or select the correct size and shape: use precise pre-cut gaskets or templates for custom shapes; avoid damaging the gasket during handling.
- Choose compatible fasteners and torque: apply recommended bolt patterns and torque according to flange standards to achieve even seating without over-compression.
- Apply appropriate gasket material strategies: graphite or PTFE gaskets may require lubricants or anti-seize compounds compatible with the media; elastomeric gaskets usually do not.
- Install evenly and seating the gasket: tighten bolts in a cross pattern to ensure uniform seating and avoid pinch points that can cause leaks.
- Inspect after commissioning: perform a proof test for leaks and verify that the gasket remains seated under operating conditions.
- Storage and handling: store gasket sheets flat, away from direct heat and sunlight, and avoid exposing elastomeric materials to solvents that can cause swelling or degradation.
What are common signs of gasket failure and how should I plan replacements?
- Visible leaks at joints or flanges, especially after thermal cycling or pressure surges
- Blistering, cracking, or cupping of the gasket surface
- Indentations, pinholes, or deformation that indicate excessive compression or inadequate seating
- Chemical attack, swelling, or softening of elastomeric gaskets when exposed to incompatible media
- Uneven bolt load or gasket blow-out under high-pressure conditions
Where can I buy gasket material from RS Components and how do I order?
- Search terms: gasket material, gasket sheet, gasket sheet material, PTFE gasket, silicone gasket, EPDM gasket, graphite gasket, Viton gasket, food-grade gasket, pharmaceutical gasket
- Filter by material type, thickness (0.5 mm to several millimeters), and specifications (temperature rating, chemical compatibility, standard sizes)
- Choose between sheets, cut gaskets, or custom shapes; add to cart and select shipping options
- Consult data sheets and compatibility information to ensure fit for your flange and media
