Parker 4010-T6 O-ring Boss Nipple 1/4 in 5000 Psi Sae

Product Description

The PARKER 4010-T6 is a straight O-Ring Boss (ORB) nipple fitting designed for hydraulic hose assemblies operating at up to 5,000 psi. Built from steel with a SAE shaft type and 9/16-18 threaded connection, it provides a reliable, leak-resistant seal in high-pressure hydraulic lines. The fitting measures 1.6 inches in overall length with a 1/4 inch body diameter and is rated for a maximum flow rate of 3.00 GPM. It is suited for hydraulic technicians and mechanics assembling or servicing fluid power systems where a secure threaded ORB connection is required.

This fitting is used in hydraulic circuits across a range of mobile and stationary equipment applications. Typical uses include add-on hydraulic circuits, hydraulic loaders, and hydraulic tools. The straight configuration simplifies routing in tight installations where inline connections are preferred. It conforms to ISO 5675 standards, making it appropriate for systems requiring compliance with that specification. The 1/4 inch hose size suits smaller-diameter hydraulic lines common in light to medium-duty tool and loader circuits.

Installation Notes

Installation should be performed by a qualified hydraulic technician or mechanic. Depressurize and isolate the hydraulic circuit completely before removing or installing any fittings. Inspect the O-ring seating surface for damage prior to assembly, and ensure the O-ring is properly seated to achieve a leak-free connection. Torque to the system or equipment manufacturer specifications only.
