Technical Description
Smallest dimensions for a couplings series according to
ISO 7241-1 series B. Particularly suitable for use with liquid media. This is a two-hand operation coupling system, i.e. the sleeve must be pushed back manually when coupling.

Advantages
High flow rate – marginal pressure drop. Plug Profile according to ISO-Norm.

Working Pressure
PB = 250 bar, maximum static
working pressure until 50°C
with safety factor of 4 to 1.

Working Temperature*
-20°C up to +100°C (NBR)
-40°C up to +120/150°C (EPDM)
-15°C up to +200°C (FKM)
depending on the medium.

*At a temperature below
-20°C and above +100°C special
seals are available on request.
