Parker 6610-16-16 Female O-ring Boss Nipple 1 in 4000 Psi

Product Description

The PARKER 6610-16-16 is a straight female O-Ring Boss (ORB) nipple fitting designed for high-pressure hydraulic hose assemblies. Built from steel with a threaded connection type, it accepts a 1-inch hose size and features a 1-5/16-12 thread size. Rated to 4,000 psi maximum working pressure, this fitting is built for demanding fluid power applications where leak-free sealing at the boss port is required. The O-ring face seal design at the boss end provides a reliable metal-to-metal-free seal, reducing the risk of leakage under pressure cycling. Licensed HVAC techs, plumbers, and hydraulic system technicians working on mobile or truck-mounted equipment will recognize this as a standard SAE-series component.

This fitting is part of the Parker 6600 Series and is intended for use in mobile hydraulic applications, including snow plow hydraulic systems and truck-trailer hydraulic connections. The straight body geometry suits installations where a direct inline connection between hose and ORB port is needed. With a maximum flow rate of 50.00 GPM and an overall length of 3.1 inches, it fits common manifold and pump port configurations found in mobile equipment and commercial vehicle hydraulic circuits.

Installation Notes

Installation should be performed by a qualified hydraulic technician or mechanic familiar with high-pressure fluid power systems. Depressurize and relieve all hydraulic pressure from the system before removing or installing any fitting. Inspect the O-ring for damage prior to assembly and ensure the boss port seat is clean and free of debris. Follow applicable SAE and ISO standards for thread engagement and fitting assembly torque as specified in the equipment service manual.
