Parker 30482-5-4B Hydraulic Hose Fitting 5/16 in 1/2-20

Product Description

The PARKER 30482-5-4B is a hydraulic hose fitting designed for use in fluid power systems requiring a secure, leak-resistant connection between hydraulic hose and line components. This fitting accommodates a 5/16-inch hose diameter and features a 1/2-20 thread size, making it suited for compact hydraulic circuits operating under pressure. It is sized for a -4 hose designation. Licensed hydraulic technicians and fluid power mechanics install fittings of this type during assembly, repair, or reconfigurations of hydraulic lines in mobile or industrial equipment applications.

This fitting is appropriate for hydraulic systems where a 5/16-inch hose diameter and 1/2-20 thread specification are required. It is commonly installed in compact or medium-duty hydraulic circuits found in mobile machinery, industrial equipment, and stationary fluid power systems. The -4 hose size designation aligns with standard hydraulic hose sizing conventions used across a broad range of equipment platforms. Fluid power technicians select this fitting during line assembly or maintenance where precise thread and hose compatibility is essential to system integrity.

Compatibility

Designed as a replacement or assembly fitting for hydraulic hose systems requiring a -4 hose size, 5/16-inch hose diameter, and 1/2-20 thread specification. No additional specific model or system compatibility data was provided in the product information.

Installation Notes

Installation should be performed by a qualified fluid power technician or hydraulic mechanic. Always depressurize and isolate the hydraulic circuit fully before disconnecting or installing any hose fitting. Use appropriate wrenches to achieve proper thread engagement without cross-threading or over-torquing the fitting body. Inspect hose ends and mating ports for damage or contamination before assembly to prevent system leaks or premature fitting failure.
