Hydraulic ,Mold Coolant-line Quick Couplers

Specifications Thread Locked Type Hydraulic Couplings

1.Accept Many European types of plugs

2.Single handed operation.

3.Robust and tough

    Thread Locked Type Hydraulic Couplings   Features: 1.Machined from solid steel barstock for durability 2. This series employs a threaded sleeve locking mechanism, mates with matching male threads on the nipple. The two  halves must be manually threaded together for connection. 3. Hard, chrome alloy balls are used for valving. They are spring loaded for positive seating of the valve. 4. The interface seal in the coupler is Polyurethane which  resists high pressure extrusion. Applications:   The couplings with their threaded union locking system and precision ball-type check valves,are designed for extreme high pressure applications such as found on  portable hydraulic rams.See pages noted in Table of Contents for dust plugs and caps for the full line of hydraulic couplngs.

   Selection Guidelines:   1. Moldmate couplings are designed for a maximum working pressure of 200 PSI.Most thermoplastic and thermoset heat transfer systems have pumps which provide relatively high flow rates at relatively low pressures.Water and water glycol(anti-freeze) systems usually have capacities ranging from 10 to 40 gpm,with most from 10 to 15 gpm.Normal medial opening pressures are 20 to 60 PSI.However,their flow rates are usually much higher,requiring the total volume of oil to be circulated at least once per minute.  2. The number of hose connections in a single mold system results in a cumulative pressure drop.Please note the Pressure Drop vs.Flow Rate chart provided,to select the appropriate. 3. Temperature is another important consideration.Parker moldmate couplings with their standard Silicone seal have a temperature capability of -68degree to +20degree.Rapid deterioration of the seal and leakage may result if used beyond these limits. 4. Extemal conditions of temperature,corrosive atmospheres,and other abnormalities may affect coupling performance and must be considered when selection is made.
