Unions

Integraflow offers a complete range of hygienic stainless steel unions in imperial sizes, designed for clean process installations in the food, dairy, brewery, beverage, pharmaceutical, and cosmetic industries. All union types are manufactured from 316L stainless steel and designed to provide a secure, hygienic connection that can be disassembled for cleaning or maintenance.

We stock the following union types:

  • RJT (Ring Joint Type) — British standard hygienic union commonly used in the UK food and dairy industries. Consists of a nut, liner, male part, and hygienic seal.

  • Tri Clamp (Triclamp) — Quick-release clamp union with a gasket and clamp ring. Ideal for clean, tool-free assembly and disassembly. Compatible with BS 4825 Part 3 and ASME BPE.

  • SMS (Swedish Milk Standard) — Smooth-bore union with a compact design, widely used in Europe for dairy and beverage applications.

  • DIN Unions — Metric unions to DIN 11851 standard, used widely across European process plants. Suitable for metric pipe systems.

  • IDF (International Dairy Federation) — Similar to RJT but with a flush internal bore for improved flow and cleanability. Common in dairy and pharmaceutical setups.

All hygienic unions are:

  • CIP and SIP compatible

  • Available in 1” to 4” OD imperial sizes

  • Supplied with seals and full traceability

  • Manufactured to ensure smooth, crevice-free joints and ease of disassembly

Fast UK-wide supply available from Integraflow, with gaskets and replacement parts also stocked.
