Water and Coolant Quick Couplings

ST Series Ideal for applications such as high-pressure water, steam washers and carpet cleaners.
Water Service
High Flow Coupler		 Permits maximum flow with minimum pressure drop. Used where water hoses are connected and disconnected frequently.
Moldmate For connecting coolant lines to mold and dies, on injection molding machinery in the plastics and die casting industries.

ST (Straight Thru) Series

Description:
Parker ST Series couplings are non-valved for applications where maximum flow is required. They offer the lowest pressure drop of any quick coupling design and are ideal for applications such as high-pressure water, steam washers and carpet cleaners.

General Specifications:
Temperature Range: -40° to +250°F;  * Flow is dependent on temperature and pressure, for more information see General Specifications, below.
