Parker PP-00545 Male Rigid Hydraulic Hose Fitting

Product Description

The PARKER PP-00545 is a male rigid straight fitting designed for hydraulic hose assemblies in high-pressure fluid power systems. Constructed from steel, this threaded fitting uses an NPTF connection to provide a pressure-tight seal without additional sealant. It measures 2.72 inches in overall length and is sized for hoses with a 0.5 inch inside diameter, corresponding to a Size 8 hose designation. The 1/2-14 thread size is a standard taper pipe thread pattern. Licensed hydraulic technicians and fluid power specialists install this type of fitting when terminating or repairing hydraulic hose runs in mobile or industrial equipment.

This fitting is a Series 77 male rigid end fitting suited to straight-run hose terminations in hydraulic circuits. It is specified for use with Parker hose lines including 387 TC ST, 487 TC ST, 787 TC ST, and 797 TC ST hose series. These hose types are commonly found in industrial machinery, mobile equipment, and construction applications where reliable high-pressure fluid routing is required. The straight geometry simplifies routing in systems where a direct inline connection is acceptable.

Compatibility

Specified for use with Parker 387 TC ST, 487 TC ST, 787 TC ST, and 797 TC ST hydraulic hoses in Size 8 with 0.5 inch inside diameter.

Installation Notes

Hydraulic fittings of this type are installed by licensed fluid power technicians or qualified industrial mechanics. Depressurize and isolate the hydraulic circuit fully before removing or installing any hose or fitting. NPTF threads are designed to seal on the thread taper itself; inspect threads for damage and ensure the correct torque is applied per the equipment manufacturer's specifications. Follow applicable OSHA and fluid power industry guidelines for hydraulic hose assembly and pressure testing before returning the circuit to service.
