Parker PT-00023 Steel Flared Tube Connector 1-1/4 in

Product Description

The PARKER PT-00023 is a steel flared tube connector designed for high-pressure hydraulic and fluid power applications. It features a 37-degree flare seat on one end and an O-ring boss (ORB) thread on the other, providing a leak-resistant connection between flared tubing and ORB-ported components. With a maximum dynamic working pressure of 4000 psi, this connector is built for demanding service environments. The 1-5/8-12 thread size mates with standard ORB ports, and the 1-1/4-inch tube OD flare end accepts correspondingly sized steel tubing. Licensed HVAC technicians, industrial plumbers, and hydraulic system technicians are the typical installers.

This connector is used in hydraulic lines, refrigeration piping, and fluid power circuits where a transition from flared tubing to an ORB-ported valve, manifold, or component is required. It is suited for both stationary and mobile equipment applications. The 37-degree flare geometry is the SAE-standard angle used widely in hydraulic and high-pressure fluid systems. Installation is performed by qualified technicians working on systems carrying hydraulic oil, refrigerant, or other pressurized fluids up to 4000 psi dynamic working pressure.

Key Features

• 37-degree SAE flare seat for reliable metal-to-metal sealing on the tube end
• O-ring boss (ORB) thread provides a positive, leak-resistant port connection
• 4000 psi maximum dynamic working pressure for high-demand hydraulic service
• 1-1/4-inch tube OD flare end with 1-5/8-12 ORB thread
• Steel construction for strength and durability in pressurized systems

Compatibility

Designed as an OEM-style replacement or service fitting for hydraulic and fluid power systems requiring a 1-1/4-inch tube OD, 37-degree flare to 1-5/8-12 ORB straight connector.

Installation Notes

Installation should be performed by a qualified hydraulic technician or licensed plumber. Depressurize and fully isolate the hydraulic or fluid system before removing or installing any fittings. Inspect the flare seat and ORB port for damage or contamination before assembly, and ensure the O-ring is properly seated and lubricated. Torque the ORB end to the fitting manufacturer's standard specification for the thread size; do not overtighten the flare nut, as this can distort the flare seat and cause leakage.
