Hygienic Unions


RJT Unions

RJT Fittings

  • The RJT union (Ring Joint Type) was the original hygienic fitting used in the U.K. It can be recognised by the slim hexagon nut and O section joint ring. Although still widely used because of comparative costs, it is not considered suitable for modern systems which are cleaned in place, because the crevice between the liner and the spigot on the male is difficult to clean. However, the positive location of the joint ring in the male part and the course whitworth thread make this a common choice where regular dismantling takes place for cleaning.
    RJT union parts conform generally toB.S. 4825 part 5 ( formerly B.S.1864 )

  • size range 1″ – 4″


Triclover Union

  • The clamp union originated in America and is the standard used in the Pharmaceutical industry. The union consists of two identical “ferrule” halves between which is a seal, profiled to give a true crevice free bore. The assembly is secured together by an outer clamp, which when tightened with the wing nut, compresses the seal ring by acting on the back tapered faces of the ferrule flanges. The assembly can be dismantled without the aid of tools.

IDF Union

  • IDF ( International Dairy Federation ) sometimes referred to as ISS, ( International Sanitary Standard )
    was introduced in the Sixties as the successor to RJT because of its crevice free assembly. It can be recognised by the wide hexagon nut or T section joint ring. The joint ring locates on both liner and male part but does not tend to stay in place when the union is disassembled, and can prove awkward. In cases where the union is dismantled frequently, the use of the L section joint ring will alleviate the problem as the joint ring will locate on one half IDF union parts conform generally to BS 4825 part 4
  • Crevice free
  • 16 Bar working pressure
  • 316 SS wetted parts
  • wide range of seal materials available, Nitrile, Silicone, EPDM, PTFE
  • size range 1″ – 4″


SMS Union

  • The SMS union is the Swedish standard hygienic fitting. It can be recognised by the round slotted nut and square section joint ring. Probably the most widely used hygienic fitting worldwide, there is always a small crevice between the face of the male spigot and the liner which makes CIP questionable. The use of L section joint rings with the standard union parts should be avoided as the male spigot can cut the lip on the joint ring causing subsequent product contamination. Where a true crevice free assembly is required, the SMS Aseptic union should be used.
