Parker PN353-70 Male Pipe Thread Extended Nipple 3/8 in

Product Description

The PARKER PN353-70 is a male pipe thread extended nipple fitting designed for hydraulic hose assemblies. Machined from brass, it features a 3/8 inch NPTF thread that forms a pressure-tight, dryseal connection without additional sealant. Rated to 200 psi, this non-valved fitting is part of the Moldmate series and handles operating temperatures from -20 degrees F to 400 degrees F. It is installed by hydraulic system technicians and industrial plumbers working on fluid-power circuits, tooling systems, and process lines that require reliable male pipe thread terminations.

This fitting is suited for low-to-moderate pressure hydraulic and fluid-transfer applications in both industrial and light commercial environments. The extended nipple body provides additional thread engagement for deep-socket or manifold-block installations where standard-reach nipples may not seat properly. Its brass construction makes it a practical choice for circuits where corrosion resistance and machinability matter, such as mold cooling lines, hydraulic control circuits, and general fluid handling assemblies.

Key Features

• 3/8 inch NPTF dryseal thread for leak-free connections without pipe dope or tape
• Rated to 200 psi working pressure
• Wide temperature range: -20 degrees F to 400 degrees F
• Brass body provides corrosion resistance for fluid-power and cooling circuits
• Non-valved design allows unrestricted flow when connected
• Extended nipple geometry suits deep-socket and manifold-block installations

Compatibility

Designed as an OEM-style replacement or service fitting for hydraulic hose assemblies and fluid-power systems requiring a 3/8 inch male NPTF extended nipple connection point.

Installation Notes

Installation is typically performed by a licensed hydraulic technician or industrial plumber. Depressurize and drain the hydraulic circuit fully before removing or installing any fitting. NPTF dryseal threads are designed to seal on thread interference alone, but inspect threads for damage before installation and confirm full thread engagement. Torque to the fitting manufacturer's specification for the port material being threaded into; do not over-torque brass fittings into soft-metal manifolds.
