Parker 30482-4-4B Hydraulic Hose Fitting 1/4 in Brass Sae

Product Description

The PARKER 30482-4-4B is a male rigid straight fitting designed for hydraulic hose assemblies in industrial and mobile hydraulic systems. Machined from brass, this Series 82 fitting accepts hoses with a 0.25 inch (6.40 mm) inside diameter and threads onto mating ports via a 7/16-20 male SAE thread. The straight configuration and threaded connection make it a direct, low-profile solution for routing hydraulic lines where flexibility at the coupling point is not required. With an overall length of 1.51 inches, this fitting is compact enough for tight routing layouts. Licensed hydraulic technicians and fluid power specialists install this type of rigid fitting in both stationary and mobile equipment hydraulic circuits.

This fitting is rated for use with Parker 801, 804, 821, 821FR, and 836 hose series, covering a range of medium- to high-pressure hydraulic hose assemblies common in industrial machinery, construction equipment, and agricultural equipment. The male SAE straight thread design provides a reliable, leak-resistant connection when properly torqued against a mating port or adapter. This fitting ships individually and is sold in single-unit quantities, making it well suited for repair and maintenance applications.

Compatibility

Designed for use with Parker 801, 804, 821, 821FR, and 836 hydraulic hose series. Fits hoses with a 0.25 inch inside diameter (size 4). The 7/16-20 male SAE thread mates with standard SAE straight-thread hydraulic ports and adapters.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and bleed the hydraulic system fully before disconnecting any fittings or hose assemblies. Inspect the mating port threads for damage or contamination before installation, and apply the appropriate thread sealant or leave dry per system requirements for SAE straight-thread fittings. Do not over-tighten brass fittings; follow the hose and fitting manufacturer torque guidelines for the thread size.
