Material: Aluminium, stainless steel or brass (upon request)

STORZ Couplings

In many European countries storz couplings are the standard couplings for fire fighting hoses and equipment.

The couplings are often called as follows:

  • D couplings (Lug distance 31 mm) = Ø 25 mm
  • C couplings (Lug distance 66 mm) = Ø 52 mm
  • B couplings (Lug distance 89 mm) = Ø 75 mm
  • A couplings (Lug distance 133 mm) Ø 110 mm

Product Features:

  • Material: aluminum, brass or stainless steel
  • Gasket: NBR, stainless steel with gasket FKM
  • Working pressure: max. PN 16 (size D, C, B), max. PN 12 (size A)
  • Thread according to DIN ISO 228
  • Couplings with identical ends (size) can be joined to any other end with the same diameter
