Clamp Unions

Integraflow supplies high-quality Tri Clamp unions — also known as Triclamp or clamp unions — made from 316L stainless steel to BS 4825 Part 3 and compatible with ASME BPE and ISO standards. These hygienic fittings are widely used in food, dairy, brewery, beverage, pharmaceutical, and biotech processing systems.

Tri Clamp unions are designed for:

  • Tool-free, quick assembly and disassembly

  • CIP/SIP compatibility for clean and steam-in-place systems

  • Secure sealing with a clamp, ferrules, and a hygienic gasket

A standard Tri Clamp union consists of:

  • 2 x ferrules (weld or plain end)

  • 1 x clamp (single hinge or double bolt)

  • 1 x gasket (available in EPDM, silicone, Viton, or PTFE)

These fittings are ideal for systems that require frequent cleaning, maintenance, or reconfiguration. Available in imperial sizes from 1” to 4” OD, with all components fully traceable and stocked for rapid UK-wide delivery from Integraflow.
