Parker PP-00343 Hydraulic Hose Male Rigid Fitting 7/16-20

Product Description

The PARKER PP-00343 is a male rigid hose fitting designed for hydraulic fluid conveyance systems. It connects a 1/4-inch hydraulic hose to a male O-ring boss (ORB) port using a 7/16-20 thread. Constructed from steel, this fitting provides the structural integrity required for pressurized hydraulic lines in demanding service environments. The rigid design eliminates swivel movement at the connection point, making it appropriate for fixed routing applications where the hose position remains constant after installation. This type of fitting is standard in mobile hydraulic equipment, industrial machinery, and fluid power circuits serviced by hydraulic technicians and millwrights.

This fitting is used in hydraulic systems requiring a reliable, non-swivel connection between a 1/4-inch hose and an ORB-ported component such as a pump, valve, or manifold. It is suited for both mobile and stationary hydraulic equipment where fixed-angle hose routing is specified. The 7/16-20 thread is a common size in light- to medium-duty hydraulic circuits found in agricultural, construction, and industrial plant equipment. Installation is performed by qualified hydraulic technicians following system design specifications.

Key Features

• Sold in packages of 5, with a minimum order quantity of 1

Compatibility

Designed as an OEM-style hydraulic hose fitting for use with 1/4-inch hydraulic hose and Male ORB-ported hydraulic components requiring a 7/16-20 threaded connection.

Installation Notes

Installation should be performed by a qualified hydraulic technician with the system depressurized and isolated from all power sources before any fitting work begins. Inspect hose ends and port surfaces for damage or contamination before assembly. Follow the equipment manufacturer's torque specifications for ORB fittings and verify that thread engagement is correct before re-pressurizing the circuit. Hydraulic systems must be inspected for leaks after startup at working pressure.
