Data sheet
Storz coupling 25-D, 13 (1/2")mm hose, Aluminium (forged)
Item number:
STKSP 31/13 A
Example illustration
Item description
Materials:
Seal: NBR (stainless steel: FKM)
Temperature range:
-40°C to max. +110°C (Stainless steel: -15°C to max. +200°C)
Operating pressure:
max. 16 bar
Operating range:
Industry, fire brigade, refinery, agriculture, construction industry, maritime, military and catastrophe protection
Dimensions for determining the size of Storz couplings DIN sizes
lug distance 31 mm = Storz size 25-D, lug distance 66 mm = Storz size 52-C, lug distance 89 mm = Storz size 75-B, lug distance 133 mm = Storz size 110-A
Advantages:
•simple assignment of hose end and connection,
•fast connection and disconnection through a 120°-rotation,
•All couplings with the same lug distance are compatible with one another. The rule that applies is: same lug distance, same nominal size,
•large range of applications through the use of application-specific hoses,
•Aluminium forged - no danger of breakage, such as exists with cast couplings of aluminium,
•Brass - body is made of DVGW/KTW-compliant alloy.

•Brass - body is made of DVGW/KTW-compliant alloy.
•The hose does not become twisted when coupling as the socket contained in the lug part can rotate
•Thanks to "Christmas tree profile", suitable for sockets on hoses of greater wall thickness.
Optional:
with locking -VER
