Parker H3-63-T8 Female Straight Thread Nipple 3/8 in 4000 Psi

Product Description

The PARKER H3-63-T8 is a female straight thread nipple designed for hydraulic and fluid system connections in demanding industrial and mobile equipment environments. Built from steel with a threaded SAE ORB (O-Ring Boss) shaft interface, this fitting is rated to a maximum working pressure of 4,000 psi and supports a maximum flow rate of 6.00 GPM. The straight body profile and 3/4-16 thread size make it a compact, reliable termination point for 3/8 inch hydraulic hose assemblies. Licensed hydraulic technicians and industrial maintenance professionals typically install this fitting as part of custom hose assemblies or direct equipment connections.

This fitting is suited for use across a wide range of fluid handling applications including industrial hydraulic lines, mobile equipment hydraulics, food and chemical processing systems, gas lines, and water and coolant lines. Its compliance with ISO 7241-1, Series B standards makes it appropriate for both domestic and internationally specified systems. The 3/8 inch hose size and 4,000 psi pressure rating position it for mid-range hydraulic circuits found in construction equipment, agricultural machinery, and industrial processing rigs.

Compatibility

Designed for use with 3/8 inch hydraulic hose assemblies in food and chemical processing systems, gas lines, industrial hydraulic lines, mobile equipment, and water and coolant lines. Fits applications requiring a 3/4-16 female straight thread SAE ORB connection per ISO 7241-1, Series B specifications.

Installation Notes

Installation should be performed by a qualified hydraulic technician or industrial mechanic. Depressurize and bleed the hydraulic system completely before removing or installing any fittings. Inspect the O-ring seating surface for damage before assembly and replace the O-ring if any deformation or cuts are present. Verify thread engagement and fitting alignment before bringing the system back to operating pressure.
