Parker PN353-25 Male Pipe Thread Extended Nipple 3/8 in

Product Description

The PARKER PN353-25 is a brass, non-valved male pipe thread extended nipple fitting designed for use in hydraulic and fluid transfer applications requiring a secure, leak-resistant threaded connection. Built to NPTF thread standards, this straight fitting handles a maximum working pressure of 200 psi and operates across a temperature range of -20 degrees F to 400 degrees F. With a 3/8-inch hose size and 3/8-inch thread size, it provides a reliable, fixed connection point in systems where extended nipple geometry is required for reach or assembly clearance. Licensed plumbers, pipefitters, and fluid system technicians are the primary installers.

The PN353-25 is rated for use with die casting equipment and mold coolant lines, making it a practical choice in industrial manufacturing environments where coolant circuit integrity is critical. Its straight body profile and NPTF thread form create a pressure-tight seal without requiring additional sealant on properly machined ports, though thread sealant tape or compound is commonly applied in field installations. The Moldmate series designation indicates suitability for modular coolant line assemblies common in injection molding and die casting operations.

Key Features

• NPTF threaded connection for a pressure-tight mechanical seal
• 200 psi maximum working pressure rating
• Operating temperature range: -20 degrees F to 400 degrees F
• 3/8-inch hose size and 3/8-inch thread size, straight body profile
• Brass construction for corrosion resistance in coolant and hydraulic fluid service
• Non-valved design allows unrestricted flow when connected

Compatibility

Designed for use with die casting equipment and mold coolant lines as part of the Parker Moldmate series. Suitable for systems utilizing 3/8-inch NPTF threaded ports.

Installation Notes

Installation should be performed by a qualified pipefitter, plumber, or fluid system technician familiar with hydraulic and coolant line assemblies. Depressurize and drain the system fully before removing or installing any fittings. NPTF threads are designed for a dry seal, but applying a compatible thread sealant compound or tape is common practice to ensure leak-free joints in field conditions. Verify that the system operating pressure and temperature do not exceed the ratings for this fitting before returning the system to service.
