Parker PT-00333 Steel Flared Tube Connector 1-1/4 in Od

Product Description

The PARKER PT-00333 is a steel flared tube connector designed for high-pressure hydraulic and fluid power systems. It features a 37-degree flare seat on the tube side and an NPTF (National Pipe Taper Fuel) thread on the fitting end, creating a reliable metal-to-metal seal. The connector accepts 1-1/4 inch OD tubing and threads into a 1-1/4-11-1/2 NPTF port. Rated to 3000 psi maximum dynamic working pressure, this fitting is built for demanding service in both stationary and mobile hydraulic circuits. It is installed by hydraulic system technicians, industrial maintenance trades, and plumbing professionals working with high-pressure tube assemblies.

This connector is suited for use in industrial hydraulic systems, fluid transfer lines, and heavy equipment plumbing where a secure, leak-free tube-to-port transition is required. The Flare x NPTF end configuration makes it a practical choice when connecting a flared tube run to a taper-threaded port on a pump, valve, manifold, or cylinder. It is appropriate for both new installations and replacement service on existing high-pressure tube circuits.

Key Features

• 37-degree flare seat provides a metal-to-metal seal without additional sealant on the tube end
• NPTF port end creates a pressure-tight connection when properly torqued into a taper-threaded port
• 3000 psi maximum dynamic working pressure for demanding hydraulic service
• Steel construction for durability in high-pressure fluid power applications
• 1-1/4 inch OD tube size with 1-1/4-11-1/2 NPTF thread for straightforward sizing and selection

Compatibility

Designed as an OEM-style replacement or new-installation fitting for high-pressure hydraulic and fluid power tube assemblies using 1-1/4 inch OD tubing and 1-1/4-11-1/2 NPTF port threads.

Installation Notes

Installation should be performed by a qualified hydraulic technician or licensed pipefitter. Depressurize and fully drain the system before removing or installing any fittings. Inspect the flare seat and NPTF port threads for damage before assembly. Consult applicable industry standards and equipment manufacturer guidelines for proper assembly procedures on high-pressure hydraulic connections.
