Parker PN353-55 Male Pipe Thread Nipple 3/8 in 200 Psi

Product Description

The PARKER PN353-55 is a male pipe thread extended nipple fitting designed for use in hydraulic hose assemblies. Machined from brass, this non-valved fitting uses NPTF thread geometry to create a pressure-tight, dryseal connection without the need for additional sealant in most applications. It is rated to 200 psi and handles a temperature range of -20 degrees F to 400 degrees F. With a 3/8-inch thread size and 3/8-inch body diameter, the PN353-55 belongs to the Moldmate series and is a standard component for technicians building or repairing hydraulic hose connections in industrial and fluid-power systems.

This fitting is suited for hydraulic hose assemblies in light- to medium-duty fluid-power systems where a reliable male pipe thread connection point is required. The extended nipple design provides additional thread engagement length, making it a practical choice in applications where a standard-reach nipple is insufficient. It is commonly installed by hydraulic system technicians and maintenance professionals working on industrial machinery, mobile equipment, and fluid-handling systems that operate within the rated pressure and temperature limits.

Key Features

• NPTF dryseal thread form promotes leak-resistant connections under pressure
• Brass construction offers corrosion resistance in a range of hydraulic fluid environments
• 200 psi pressure rating suitable for light- to medium-duty hydraulic applications
• Operating temperature range of -20 degrees F to 400 degrees F
• Non-valved design allows unrestricted flow through the fitting
• Extended nipple profile provides added thread engagement over standard-length nipples

Compatibility

Designed as an OEM-style hydraulic hose fitting for fluid-power assemblies requiring a 3/8-inch NPTF male pipe thread extended nipple connection within the Moldmate series.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid-power professional. Depressurize and isolate the hydraulic circuit completely before removing or installing any fitting. NPTF threads are designed as dryseal connections, but verify system requirements before applying thread sealant. Inspect threads for damage before installation and torque to the system-appropriate specification per the equipment manufacturer guidelines.
