Parker PN353-40 Male Pipe Thread Extended Nipple 3/8 in

Product Description

The PARKER PN353-40 is a brass male pipe thread extended nipple fitting designed for use in hydraulic and fluid-transfer systems that require a reliable threaded connection. With a 3/8-inch body diameter and NPTF threading, this straight, non-valved fitting delivers a pressure rating of 200 psi and handles temperatures from -20 degrees F to 400 degrees F. The brass construction resists corrosion in demanding industrial environments. This fitting is part of the Parker Moldmate series and is typically installed by industrial maintenance technicians or pipefitters working on mold coolant and die casting fluid circuits.

This fitting is specifically suited for die casting equipment and mold coolant lines where consistent thread sealing and chemical resistance are essential. The Moldmate series is engineered for industrial process applications where thermal cycling and continuous fluid flow demand durable, leak-resistant connections. The NPTF thread form provides a mechanical seal without relying solely on thread sealant tape, making it a practical choice for high-cycle industrial environments where system integrity is critical.

Key Features

• Brass construction provides corrosion resistance in coolant and hydraulic media
• NPTF thread form creates a pressure-tight mechanical seal
• 200 psi maximum working pressure for hydraulic and coolant line service
• Wide service temperature range: -20 degrees F to 400 degrees F
• Straight, non-valved design for simple inline or port connections
• Part of the Parker Moldmate series 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. Suitable for systems using 3/8-inch NPTF threaded ports and connections rated to 200 psi.

Installation Notes

Installation should be performed by a qualified pipefitter or industrial maintenance technician. Depressurize and drain the system completely before removing or installing any fittings. NPTF threads are designed to seal on thread contact, but confirm proper thread engagement and inspect for leaks after system repressurization. Follow applicable facility and industry standards for fluid system assembly and torque practices.
