Parker PN352-25 Male Pipe Thread Extended Nipple Brass

Product Description

The PARKER PN352-25 is a male pipe thread extended nipple fitting designed for hydraulic and fluid transfer applications where a secure, leak-resistant threaded connection is required. Manufactured from brass with an NPTF threaded shaft, this straight fitting accommodates a 3/8-inch hose size and a 1/4-inch thread size. It carries a maximum working pressure of 200 psi and is rated for temperatures from -20 degrees F to 400 degrees F. The non-valved, straight-body design makes it straightforward to install in tight plumbing configurations. It is part of the Moldmate series and is sold individually.

This fitting is specified for use with die casting equipment and mold coolant lines, where controlled fluid flow and pressure integrity are critical. The NPTF thread form creates a pressure-tight seal without relying solely on a sealant, making it well-suited for coolant circuits that cycle through temperature extremes. Plumbers, pipefitters, and industrial maintenance technicians working on mold cooling systems will find the extended nipple profile useful for bridging gaps between components or adding reach in confined installations.

Key Features

• Brass construction resists corrosion in coolant and hydraulic fluid environments
• NPTF thread form provides a metal-to-metal pressure-tight seal
• 200 psi maximum working pressure suits typical mold coolant line requirements
• Wide temperature range: -20 degrees F to 400 degrees F
• Straight, non-valved body simplifies installation and flow path
• Part of the Moldmate series, designed for die casting and mold coolant applications

Compatibility

Designed for use with die casting equipment and mold coolant lines as part of the Parker Moldmate series. Fits 3/8-inch hose with 1/4-inch NPTF male pipe thread connections.

Installation Notes

Installation should be performed by a qualified pipefitter or industrial maintenance technician familiar with threaded hydraulic and coolant fittings. Depressurize and drain the system completely before removing or installing any fitting. NPTF threads are designed to seal on the thread form itself; apply thread sealant or tape only if required by the system manufacturer or applicable codes. Avoid over-tightening, which can crack brass fittings or distort thread sealing surfaces.
