Technical Description
The 86, 87 and 88 RECTUS Moldtite coupling series were
especially developed for connecting coolant lines and injection molds. Countersunk plugs can easily be connected and disconnected because of the extended sleeve. The angular connections prevent kinks from forming in the hose.

Advantages
Available in single shut-off,
double shut-off or straight-
through versions. The shut-
off couplings (with valve) are
equipped with nickel plated
sleeves for quick and accurate
visual differentiation.

Working Pressure
PB = 15 bar, maximum static
working pressure with safety
factor of 4 to 1.

Working Temperature*
-15°C up to +200°C (FKM)
depending on the medium.

*At a temperature below
-15°C and above +200°C special
seals are available on request.
