Parker 1717717 Hydraulic Hose Fitting 4000 Psi 3/4 in Nptf

Product Description

The PARKER 1717717 is a female pipe rigid fitting designed for hydraulic hose assemblies operating at pressures up to 4000 psi. Built from steel with an NPTF threaded connection, this straight fitting provides a leak-resistant seal in demanding fluid power systems. At 2.55 inches in overall length and a 3/4 inch body diameter, it is sized for 3/4 inch hydraulic hose. The fitting supports a maximum flow rate of 28.00 GPM. It is part of the Parker 6600 Series and meets ISO 7241-1 Series A standards. Hydraulic technicians and fleet mechanics install this fitting in mobile equipment, truck trailer connections, and snow plow hydraulic circuits.

This fitting is suited for mobile hydraulic applications where a reliable female pipe rigid connection is required. Typical installations include truck-mounted hydraulic systems, snow plow lift and angle circuits, and trailer hydraulic connections. The NPTF thread form creates a pressure-tight mechanical seal without relying solely on sealant tape, making it appropriate for systems exposed to vibration and repeated pressure cycling. The 4000 psi working pressure rating supports the demands of most mobile equipment hydraulic circuits.

Key Features

• 4000 psi maximum working pressure for high-demand mobile hydraulic systems
• NPTF threaded connection provides a mechanically sealed, dryseal-style interface
• Steel construction for durability in mobile and outdoor service environments
• Straight body shape simplifies hose routing in tight installations
• Maximum flow rate of 28.00 GPM supports full-flow circuit requirements
• Meets ISO 7241-1 Series A standards for hydraulic coupling interchangeability

Compatibility

Designed for use with mobile applications, snow plows, and truck trailer hydraulic connections. Compatible with 3/4 inch hydraulic hose assemblies requiring a female pipe rigid NPTF fitting. Part of the Parker 6600 Series hydraulic fitting line.

Installation Notes

Installation should be performed by a qualified hydraulic technician. Depressurize and relieve all hydraulic system pressure before disconnecting or assembling any fittings. NPTF threads rely on thread deformation for sealing — inspect threads for damage before assembly and use appropriate thread sealant per system requirements. Torque to the fitting manufacturer's assembly specifications and verify for leaks before returning the system to service.
