Dry Disconnect Couplings are available in sizes from ¾” up to 6” and in a wide range of materials and seals to be the given choice for almost any application. The self sealing design of the Dry disconnect couplings guarantees both the highest level of safety and also the quickest way of connecting and disconnecting. Mann Tek has knowledge from design, production and marketing of DDCouplings® since 1977.

DDCouplings®, Dry Disconnect Couplings, are designed for quick and spill free connection and disconnection of hoses and pipelines. They are used by producers of ink, adhesives, fatty acids, pharmaceuticals, liquid soaps, petroleum, chemicals, agricultural and a wide variety of caustic products and speciality acids.

DDCouplings® are especially needed in areas of zero tolerance spillage when your product:

  • is of high value
  • requires costly environmental methods of cleaning-up in case of spillage
  • is expensive to reprocess or dispose of
  • is hazardous to the environment
  • can cause a health risk
  • is prone to accidental spillage and product loss

DDCouplings® are in use in installations all over the world, especially where certification is a prerequisite and are certified by TÜV, Apragaz, Veritas, TDT, plus regionally required approvals.
