Storz couplings


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
