Parker PN252-25 Male Pipe Thread Nipple 1/4 in 200 Psi

Product Description

The PARKER PN252-25 is a male pipe thread extended nipple fitting designed for hydraulic and fluid-transfer applications where a reliable threaded connection is required. Machined from brass and rated to 200 psi maximum working pressure, this straight fitting uses an NPTF thread form to provide a pressure-tight seal without additional sealant in many applications. The 1/4-inch hose size and 1/4-inch thread size make it a compact, single-piece connection point suited for moderate-pressure lines. It is part of the Parker Moldmate series and is non-valved, meaning flow is unrestricted when connected. Licensed plumbers, hydraulic technicians, and mold-cooling system technicians are the typical installers.

This fitting is rated for use across a wide temperature range, from -20 degrees F to 400 degrees F, making it compatible with both chilled and heated fluid circuits. Primary applications include die casting equipment and mold coolant lines, where consistent, leak-free connections are critical to process uptime. The straight body profile simplifies inline installation where no directional offset is needed. Its compact body diameter of 1/4 inch suits tight plumbing runs common in industrial tooling and mold-cooling manifolds.

Key Features

• Brass construction for corrosion resistance in coolant and hydraulic fluid service
• NPTF thread form provides a pressure-tight mechanical seal
• 200 psi maximum working pressure suitable for moderate-pressure hydraulic and coolant lines
• Wide temperature range: -20 degrees F to 400 degrees F
• Straight body profile for straightforward inline installation
• 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. Compatible with 1/4-inch NPTF ported connections in non-valved, straight-fitting applications.

Installation Notes

Installation should be performed by a qualified hydraulic technician or licensed plumber familiar with NPTF threaded fittings and the relevant plumbing or fluid-power codes. Depressurize and drain the system fully before removing or installing any fitting. Inspect threads for damage before assembly, and apply thread sealant only as required by the system design, as NPTF threads are engineered for dry-seal engagement. Do not overtighten, as brass fittings can crack under excessive torque.
