Parker SSH6-63 Female Pipe Rigid Nipple Fitting 3/4 in Nptf

Product Description

The PARKER SSH6-63 is a female pipe rigid nipple fitting designed for hydraulic hose assemblies requiring a secure, leak-resistant threaded connection. Constructed from stainless steel, this fitting accepts a 3/4 inch NPTF thread and carries a pressure rating of 1,500 psi. The rigid nipple configuration provides a fixed, non-swivel connection point, making it well suited for lines where hose orientation is set at assembly. It is rated for service from -15 degrees F up to 400 degrees F, covering a broad range of hydraulic and fluid-transfer applications. Licensed plumbers, pipefitters, and hydraulic system technicians are the typical installers for this type of fitting.

This fitting is used in hydraulic hose assemblies across industrial, mobile equipment, and heavy-duty fluid-transfer systems. The NPTF thread form creates a pressure-tight seal on the threads themselves, which reduces reliance on additional sealing compounds in many installations. The stainless steel body resists corrosion in wet, chemical-exposed, or outdoor environments. It is appropriate for both new hose assembly builds and field replacement of worn or damaged fittings in existing hydraulic circuits.

Key Features

• Stainless steel construction for corrosion resistance in demanding environments
• 3/4 inch NPTF thread provides a pressure-tight threaded seal
• 1,500 psi pressure rating suitable for medium-pressure hydraulic lines
• Wide service temperature range: -15 degrees F to 400 degrees F
• Rigid nipple design keeps hose orientation fixed after assembly
• 3/4 inch body diameter matches standard hose and port sizing

Compatibility

Designed as an OEM-style replacement or new-build component for hydraulic hose assemblies requiring a 3/4 inch NPTF female pipe rigid nipple fitting rated to 1,500 psi.

Installation Notes

Installation is typically performed by a licensed pipefitter, hydraulic technician, or journeyman plumber following applicable fluid-power and piping codes. Depressurize and bleed the hydraulic circuit fully before removing or installing any fitting. NPTF threads are designed to seal on the thread form, but inspect threads for damage and apply appropriate thread sealant per system requirements and fluid compatibility. Torque to the fitting manufacturer and system designer specifications — do not overtighten stainless steel fittings, as galling can occur.
