Parker PS690102-6-6 Npt Swivel Fitting 3/8 in 5000 Psi

Product Description

The PARKER PS690102-6-6 is a straight male NPT to female NPT swivel fitting designed for hydraulic hose assemblies operating at up to 5,000 psi. Constructed from steel, this fitting measures 3.05 inches in overall length and accepts 3/8-18 NPT threads on both ends. The swivel design on the female NPT side allows the hose or downstream component to rotate freely during installation, reducing stress on the hose and preventing assembly twist. It is a Series PS fitting intended for use in high-pressure hydraulic circuits by fluid power technicians, maintenance mechanics, and hydraulic system assemblers.

This fitting is suited for mobile hydraulic equipment, industrial hydraulic machinery, and fluid power systems where a straight in-line NPT transition is required. Typical applications include connecting hydraulic hoses to pumps, cylinders, valves, and manifolds with standard NPT ports. The 3/8 inch hose size and 3/8-18 thread size make it a common choice for mid-range flow circuits in both shop and field service environments.

Key Features

• Rated to 5,000 psi maximum working pressure for demanding hydraulic service
• Steel construction for durability in high-pressure fluid power applications
• Swivel female NPT end allows rotation during installation to prevent hose twist
• Straight configuration for direct in-line NPT-to-NPT connections
• 3/8-18 NPT thread size on both male and female ends
• Overall length of 3.05 inches fits standard hose assembly layouts

Compatibility

Designed as an OEM-style replacement or new-installation fitting for hydraulic hose assemblies using 3/8 inch hose with 3/8-18 NPT ported connections.

Installation Notes

Installation should be performed by a qualified fluid power technician or hydraulic systems mechanic. Depressurize and de-energize the hydraulic circuit completely before removing or installing any fittings. Apply appropriate thread sealant compatible with hydraulic fluid to the male NPT threads before assembly. Inspect threads and sealing surfaces for damage before torquing to avoid leaks under pressure.
