Parker 6601-16-16 Hydraulic Hose Fitting 4000 Psi 1 in

Product Description

The PARKER 6601-16-16 is a female pipe rigid fitting designed for high-pressure hydraulic hose assemblies in demanding mobile and industrial environments. Built from steel with a straight, threaded NPTF configuration, this fitting handles working pressures up to 4,000 psi and supports flow rates up to 50 GPM. With a 1-inch hose size, 1-inch thread size, and an overall length of 4.11 inches, it provides a secure, leak-resistant connection at hose termination points. It is typically installed by hydraulic system technicians, heavy equipment mechanics, and fleet maintenance professionals who require reliable fittings in high-cycle or high-vibration service conditions.

This fitting is part of PARKER's 6600 Series and is rated for use in mobile applications where robust hydraulic connections are critical. Noted compatible applications include snow plows and truck-trailer hydraulic connections. The straight body geometry simplifies routing in tight or fixed-orientation plumbing configurations. Its NPTF thread form provides a pressure-tight mechanical seal without relying solely on thread sealant, making it well suited for field assembly and repair work.

Compatibility

Designed for use in mobile applications, snow plows, and truck-trailer hydraulic connections. Part of the PARKER 6600 Series of hydraulic hose fittings for 1-inch hose and 1-inch NPTF threaded ports.

Installation Notes

Installation should be performed by a qualified hydraulic technician or mechanic familiar with high-pressure fluid systems. Depressurize and fully bleed the hydraulic circuit before removing or installing any fitting. NPTF threads are designed for dry-seal assembly, but apply thread sealant per the system manufacturer's guidance if required by the application. Inspect threads and sealing surfaces for damage before assembly and torque to the fitting manufacturer's specifications using a calibrated torque wrench.
