Parker P00111 Steel Flared Tube Connector 1-1/4 in Od

Product Description

The PARKER P00111 is a steel flared tube straight thread connector designed for high-pressure hydraulic and fluid power plumbing applications. It features a 37-degree flare on the tube end and an SAE O-Ring Boss (ORB) straight thread on the port end, creating a leak-resistant connection between a flared tube and a threaded port. The tube OD is 1-1/4 inches with a 1-5/8-inch UNF thread, and the fitting is rated for a maximum dynamic working pressure of 4000 psi. Plumbers, hydraulic system technicians, and industrial maintenance professionals install this type of connector when transitioning from a flared tube line to an ORB-ported component.

This connector is suited for medium to large-bore hydraulic lines in industrial, mobile equipment, and heavy-duty fluid power systems. The 37-degree flare conforms to JIC flare standards, which are common in hydraulic plumbing across manufacturing, construction equipment, and agricultural machinery. The SAE-ORB port end threads into manifolds, pumps, valves, and cylinders with standard ORB ports, providing a reliable metal-to-O-ring face seal at the port side.

Key Features

• 37-degree JIC flare tube end for secure, leak-resistant tube connection
• SAE O-Ring Boss (ORB) straight thread port end reduces port-side leakage
• 1-1/4 inch tube OD accommodates large-bore hydraulic lines
• UNF thread standard with 1-5/8 inch thread size
• Rated to 4000 psi maximum dynamic working pressure
• Steel construction for durability in high-pressure service

Compatibility

Designed as an OEM-style replacement or new-installation fitting for hydraulic and fluid power systems using 37-degree flare tube connections and SAE O-Ring Boss ported components.

Installation Notes

Installation should be performed by a qualified hydraulic technician or pipefitter. Depressurize and drain the hydraulic system completely before removing or installing any fittings. Inspect the flare and O-ring seating surfaces for damage before assembly, and replace the O-ring if worn or missing. Follow applicable industry standards for hydraulic fitting assembly, and do not over-tighten, as this can damage the flare seat or thread.
