Parker PT-00123 Steel Flared Tube Connector 1-1/4 in Od

Product Description

The PARKER PT-00123 is a steel flared tube connector designed for high-pressure hydraulic and fluid system applications. It features a 37-degree flare end on the tube side and a NPTF threaded end on the port side, creating a leak-resistant mechanical seal without the need for additional thread sealant. The connector accepts 1-1/4 inch outside diameter tubing and is rated for a maximum working pressure of 2500 psi. Built from steel, it delivers the strength and durability required in demanding fluid power and plumbing installations. Hydraulic technicians and pipefitters install this type of fitting when transitioning between flared tubing and NPT-ported components.

This connector is suited for use in hydraulic lines, fluid transfer systems, and compressed air plumbing where a 37-degree JIC-style flare meets an NPTF port. Typical installation scenarios include connecting steel tubing runs to pumps, cylinders, valves, and manifolds in both industrial and mobile equipment environments. The NPTF thread form provides a dry-seal connection that meets common fluid power system requirements.

Key Features

• 37-degree flare end for reliable, leak-resistant tube seating
• NPTF thread standard provides a dry-seal port connection
• 1-1/4 inch tube OD accommodates standard large-bore steel tubing
• 2500 psi maximum working pressure rating
• Steel construction for high-strength fluid power service

Compatibility

Designed as an OEM-style replacement or service fitting for hydraulic and fluid power systems using 1-1/4 inch OD steel tubing with 37-degree flare ends and 1-1/4-11-1/2 NPTF threaded ports.

Installation Notes

Installation should be performed by a qualified hydraulic technician or pipefitter familiar with fluid power system standards. Depressurize and drain the hydraulic or fluid system completely before removing or installing any fittings. The NPTF thread form is designed for a dry-seal connection, but consult the system manufacturer guidelines before applying any thread compounds. Inspect the flare seat and tube end for damage before assembly to ensure a proper seal.
