Parker PX-00291 Hydraulic Hose Male Connector Nptf Steel

Product Description

The PARKER PX-00291 is a straight male connector fitting designed for hydraulic hose assemblies requiring a secure, leak-resistant threaded connection. Built from steel, this fitting features a 1/8-27 NPTF thread and a 0.125 inch inside diameter, making it suited for small-bore hydraulic and fluid-transfer lines. The NPTF (National Pipe Taper Fuel) thread form creates a pressure-tight mechanical seal without requiring additional sealant tape. At 1.89 inches in overall length, the PX-00291 is a compact, straight-configuration connector. It is part of the Parker CY Series and is sold in a package quantity of four. Licensed plumbers, pipefitters, and hydraulic system technicians are the primary installers.

This fitting is used in hydraulic plumbing circuits, fluid-transfer assemblies, and small-bore tubing systems where an NPTF male-threaded port connection is required. Typical applications include low-to-medium pressure hydraulic lines on mobile equipment, industrial machinery, and fluid power systems. The straight configuration suits inline port entries where no angular offset is needed. Sold in packages of four, this fitting is well suited for service shops and field technicians stocking common connection hardware.

Compatibility

Designed as an OEM-style replacement or service fitting for hydraulic hose assemblies using 1/8-27 NPTF threaded male connector ports in small-bore fluid power systems.

Installation Notes

Installation should be performed by a qualified pipefitter, hydraulic technician, or licensed plumber. Always depressurize and drain the hydraulic circuit completely before removing or installing fittings. NPTF threads are designed to seal on the thread form itself; inspect threads carefully before assembly and avoid cross-threading. Follow applicable fluid power standards and equipment manufacturer torque guidance when tightening.
