Parker H3-63 Hydraulic Hose Fitting 3/8 in 4000 Psi Nptf

Product Description

The PARKER H3-63 is a female pipe rigid fitting designed for use in hydraulic hose assemblies and fluid transfer lines. Built from steel with an NPTF threaded connection, this straight fitting delivers a maximum working pressure of 4000 psi and a maximum flow rate of 6.00 GPM (23.00 LPM). At 1.68 inches in overall length and weighing 0.127 pounds, it is a compact, heavy-duty component suited for mobile equipment, industrial hydraulic lines, and fluid processing systems. Licensed trades and industrial maintenance professionals install this fitting wherever a reliable female pipe rigid connection is required at moderate flow rates.

The H3-63 is suited for a wide range of fluid system applications including industrial hydraulic lines, mobile equipment circuits, food and chemical processing lines, gas lines, and water and coolant lines. Its straight body geometry and NPTF thread form make it a common choice for direct inline connections in both stationary and mobile hydraulic assemblies. This fitting is part of the Parker Series 60 product line and conforms to ISO 7241-1, Series B standards.

Installation Notes

Installation should be performed by a qualified hydraulic technician or licensed mechanic. Depressurize and bleed down the hydraulic system completely before disconnecting or installing any fittings. NPTF threads are designed for dry-seal assembly; inspect threads for damage before installation and follow standard torque practices for steel hydraulic fittings. Verify that hose end connections and mating components are compatible in thread size and pressure rating before placing the system back in service.
