Guidelines for Selection and Use:
Non-valved couplers provide maximum flow for efficient
cooling. Valved couplers shut off automatically when
disconnected. Valved couplers can be used with either valved
or non-valved nipples. A valved nipple, however, must be used
with a valved coupler.
Moldmate couplings are rated for 200 psi max pressure. Most
thermoplastic and thermoset heat transfer systems have pumps
which provide relatively high flow rates at low pressures. Water
and water glycol 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 for these systems. Heat
transfer systems using oil gen­er­al­ly operate from 10 to 30 psi.
However, their flow rates are usually much higher, requiring
the total volume of oil to be cir­cu­lated at least once per minute.
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 size.
Temperature is another important con­sid­era­tion. Parker
Moldmate couplings with the standard sili­cone seal have a
temperature capability of -90° to +400°F. Rapid deterioration
of the seal and leakage may result if used beyond these limits.
External conditions of temperature, corrosive at­mo­spheres,
and other ab­nor­mal­i­ties may affect coupling performance
and must be considered when selection is made. Con­sult QCD
with questions.

Hydraulic Quick Couplings
Mold Coolant
Moldmate series couplings are specifically designed for
connecting coolant lines to molds and dies on injection molding
machinery and die casting equipment. These couplings
significantly reduce downtime, by providing a quick and easy
way to connect and disconnect lines during mold changes.
Features:
•
Rated pressure is 200 psi
•
Valved and unvalved options. Valved couplers have silver
colored sleeves
•
Brass material with standard silicone interface seals are
compatible with water and water glycol fluids. Valved
versions have a fluorocarbon seal on the poppet.
•
Optional fluorocarbon seal for use with oil based media
•
Short nipples can be installed recessed below the mold
surface enabling more efficient storage and protecting the
nipple from damage
•
Standard and Push-Lok hose barb ends are available in
straight, 45 or 90 degree configurations
•
Manual sleeve operation
•
Extension nipples are offered in several lengths
Applications:
•
Mold coolant lines
•
Die casting equipment
Special Order Information:
Standard seal material is Silicone and is com­pat­i­ble with
water and water glycol fluids com­mon­ly used in heat transfer
systems. Fluorocarbon seals are available for use with oil-
based media. To specify a Fluorocarbon seal, add the suffix “Y”
to the standard moldmate part number, thus: PC206Y.
