When it comes to the food and beverage industry, selecting the right sealing material is one of the most critical decisions for ensuring safety, hygiene, and efficiency. Gaskets and seals play a vital role in preventing leaks, contamination, and costly downtime. With strict regulations and demanding operating conditions, choosing the best gasket material for food processing equipment is essential.

Why the Right Sealing Material Matters

Food processing machinery is subject to high temperatures, aggressive cleaning cycles, oils, acids, and continuous wear. A poorly selected gasket can cause failures, contamination risks, or non-compliance with food safety standards. The right sealing solution ensures:

  • Compliance with food safety standards (FDA, EU regulations, NSF approvals).
  • Durability under extreme temperatures from freezing to steam sterilisation.
  • Resistance to chemicals and cleaning agents used in sanitisation.
  • Tight, reliable seals that prevent leaks and bacterial growth.

Top Sealing Materials Used in the Food Industry

1. Food-Grade Silicone Gaskets

  • Heat resistance up to 230°C.
  • Flexible and safe for direct food contact.
  • Ideal for ovens, mixers, and equipment exposed to steam.
  • Resistant to cleaning chemicals, ensuring long service life.

2. EPDM Rubber Gaskets

  • Excellent resistance to steam, hot water, and weathering.
  • Cost-effective choice for dairy, beverage, and brewing applications.
  • Strong against alkalis and some acids, though less resistant to oils.

3. PTFE (Teflon) Gaskets

  • Chemically inert and highly resistant to oils, fats, and aggressive cleaning agents.
  • Excellent non-stick properties, making them easy to clean.
  • Perfect for high-acid or high-oil food processes.

4. Nitrile (NBR) Gaskets

  • Strong resistance to animal fats, oils, and hydrocarbons.
  • Widely used in meat processing and frying equipment.
  • Not as durable under steam sterilisation compared to silicone or PTFE.

Key Factors to Consider When Choosing

  1. Temperature Range – Can the gasket handle both heating and cooling cycles?
  2. Cleaning Requirements – Is it resistant to detergents, disinfectants, or CIP (clean-in-place) systems?
  3. Food Contact Safety – Always verify FDA or EU food-grade compliance.
  4. Durability & Cost – Balance initial investment with long-term replacement frequency.
  5. Custom Fit – CNC-cut gaskets ensure precise dimensions and tight seals for unique machinery.
Final Thoughts

Selecting the correct sealing material for food processing equipment is not just about price—it’s about hygiene, compliance, and long-term performance. From food-grade silicone gaskets for high-temperature baking to EPDM gaskets for breweries and PTFE gaskets for chemical resistance, every material has its strengths.
