Parker 71-3N12-12F Hydraulic Hose Valve Fitting 3/4 in 7500 Psi

Product Description

The PARKER 71-3N12-12F is a straight hydraulic hose valve fitting designed for high-pressure fluid control in industrial and off-shore hydraulic systems. Machined from steel with an NPTF threaded connection, this fitting handles a maximum working pressure of 7,500 psi and an overall length of 2.96 inches. It is rated for service from -35 degrees F to 250 degrees F, making it suitable for demanding environments where temperature swings and pressure spikes are routine. Hydraulic technicians and pipefitters install this type of fitting when terminating or valving off hose assemblies on high-pressure lines.

This fitting is sized for 3/4-inch hose with a 3/4-inch NPTF thread and belongs to the Parker Series 71 product line. It is suited for industrial hydraulic lines and off-shore drilling applications where a secure, leak-resistant threaded connection is required. The straight body shape simplifies inline installation and reduces the number of adapters needed in tight plumbing runs.

Installation Notes

Installation should be performed by a qualified hydraulic technician or pipefitter familiar with high-pressure fluid system procedures. Depressurize and bleed down the hydraulic system fully before removing or installing any fittings. NPTF threads are designed for dry-seal assembly; use appropriate thread sealant only if required by the system specification and applicable codes. Inspect threads and seating surfaces for damage before assembly to ensure a leak-free connection at rated pressure.
