Seals

Integraflow stocks a complete range of RJT seals in all major materials for hygienic process systems. Designed to fit RJT unions to BS 4825 Part 5, these gaskets provide the critical sealing interface between the RJT liner and male part when clamped with a hex nut.

We offer RJT seals in the following materials:

  • NBR (Nitrile) – general-purpose food-grade rubber suitable for water, oils, and dairy applications.

  • Viton (FKM) – high-performance seal for chemical resistance and elevated temperature environments.

  • Silicone – flexible and stable across a wide temperature range; commonly used in beverage and cosmetic lines.

  • PTFE (Teflon) – non-stick, chemically inert, and suitable for aggressive or high-purity applications.

All gaskets are manufactured to precise tolerances and are fully compatible with clean-in-place (CIP) and steam-in-place (SIP) systems. Seals are available in imperial sizes from 1” to 4” and are suitable for use in food, dairy, beverage, and pharmaceutical process lines.

Fast UK-wide supply available from Integraflow, with full compatibility across our RJT nuts, liners, and male parts.
