Parker 1/4 DD45-S 45 Degree Female Elbow Fnptf 5000 Psi

Product Description

The PARKER 1/4 DD45-S is a 45-degree female elbow fitting designed for industrial pipe and fluid system assemblies. It accepts a 1/4 inch female thread with FNPTF (Female National Pipe Taper Fuel) thread form, providing a pressure-rated, leak-resistant connection. Rated to 5,000 psi maximum working pressure, this fitting is built from zinc-plated steel for corrosion resistance in demanding service environments. Licensed plumbers, pipefitters, and industrial maintenance technicians install this type of fitting to redirect flow at a 45-degree angle in threaded pipe assemblies.

This fitting is suited for hydraulic, pneumatic, and fluid transfer lines in industrial and commercial installations where high-pressure rated threaded connections are required. The FNPTF thread form is commonly used in fuel, oil, and fluid handling systems. Its compact size and standard 1/4 inch thread make it a practical choice for tight routing situations in equipment, machinery, or panel-mounted piping configurations.

Key Features

• 45-degree elbow geometry for directional flow changes in tight installations
• 1/4 inch FNPTF female thread on both ends for all-female threaded connections
• 5,000 psi maximum working pressure rating
• Zinc-plated steel construction for corrosion resistance
• Compact, lightweight form factor at 0.01 pounds

Compatibility

Designed as an OEM-style replacement or new-installation fitting for industrial threaded pipe systems using 1/4 inch FNPTF connections rated up to 5,000 psi.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter following applicable codes such as the IPC or IFGC. Depressurize and isolate the line completely before removing or installing any threaded fittings. Apply thread sealant appropriate for the service fluid and pressure rating. Do not over-tighten, as this can damage the FNPTF thread form and compromise the seal.
