Parker 11143-4-4 Hydraulic Hose Fitting 1/4 Inch

Product Description

The PARKER 11143-4-4 is a hydraulic hose fitting designed for use in fluid power systems requiring a secure, leak-free connection between hose and port. This fitting carries a -4 hose size designation with a 1/4 inch hose diameter and 1/4 inch thread size, making it suited for compact hydraulic lines operating at moderate pressure. Parker fittings are manufactured to close tolerances, ensuring consistent sealing performance across high-cycle hydraulic circuits. Licensed hydraulic technicians and fluid power mechanics are the primary installers of this component in both mobile and stationary hydraulic equipment.

This fitting is used in hydraulic systems where -4 hose assemblies terminate at pumps, cylinders, valves, or manifolds with 1/4 inch ported connections. Common applications include industrial machinery, mobile equipment, and light construction equipment hydraulic circuits. The compact thread and hose size make it a practical choice for routing lines in tight spaces where larger fittings are not practical. Package quantity is one fitting per unit.
