Quick Connect Water Couplings

Moldtite Couplings are specially designed for connecting coolant lines to molds and dies. Couplers and plugs are available in non-valved straight-thru and valved shut-off designs, with standard or push-lock hose barbs.

For maximum unrestricted flow, we recommend the non-valved straight-thru coupler and non-valved straight-thru plug combination.

Where loss of fluid in the mold or die (when disconnected) is of prime concern, a valved shut-off coupler with a valved shut-off plug is recommended. When the increase in flow is more important than the loss of fluid, the valved shut-off coupler can be connected with a non-valved straight-thru plug. However, a valved shut-off plug cannot be used without a valved shut-off coupler.

Push-lock couplers should be used with push-lock hose, eliminating the need for hose clamps.
