Parker PN351-85 Male Pipe Thread Nipple 1/8 in 200 Psi

Product Description

The PARKER PN351-85 is a male pipe thread extended nipple fitting designed for hydraulic hose assemblies. Machined from brass, this non-valved fitting uses NPTF thread form to provide a pressure-tight, dryseal connection without the need for sealant tape in many applications. It carries a pressure rating of 200 psi and handles operating temperatures from -20 degrees F to 400 degrees F. The 1/8 inch thread size and 3/8 inch body diameter suit compact hose end connections in fluid power and hydraulic systems. Licensed HVAC, plumbing, and hydraulic technicians install this fitting as part of hose assembly fabrication or field repair work.

The PN351-85 is part of the Parker Moldmate series, which targets hydraulic hose end fittings for industrial and light-duty fluid power applications. Its brass construction makes it appropriate for systems where corrosion resistance is a priority and where compatibility with petroleum-based or water-based hydraulic fluids is required. The extended nipple design provides additional thread engagement and clearance in tight plumbing layouts. This fitting is sold individually and is suitable for shop fabrication or on-site hose assembly repairs.

Installation Notes

Installation should be performed by a qualified hydraulic or plumbing technician. Depressurize and drain the hydraulic system completely before removing or installing any fitting. NPTF dryseal threads are designed to seal on thread contact, but always verify system-specific requirements before omitting thread sealant. Follow applicable industry standards and equipment manufacturer guidelines for torque and assembly procedures.
