Parker 1/4 Dd-s 90 Degree Female Elbow 1/4 Inch Fnptf

Product Description

The PARKER 1/4 DD-S is a 90-degree female elbow fitting designed for high-pressure industrial pipe assemblies. Constructed from zinc-plated steel, it provides corrosion resistance in demanding environments. The fitting uses FNPTF (Female National Pipe Taper Fuel) threading at 1/4 inch and is rated for a maximum working pressure of 5,000 psi. Licensed plumbers, pipefitters, and industrial maintenance technicians install this type of fitting where a right-angle directional change is required in a threaded pipe system. The zinc plating adds a layer of protection against rust and oxidation in both indoor and light-exposure outdoor applications.

This fitting is suited for high-pressure fluid and gas line assemblies in industrial, commercial, and heavy-duty trade environments. It is commonly used in hydraulic lines, compressed air systems, fuel lines, and other piping networks that require a 90-degree turn at a female-threaded connection point. The FNPTF thread form creates a pressure-tight seal at the threads themselves, making it appropriate for fuel and fluid service where leak integrity is critical.

Key Features

• 90-degree female elbow configuration for right-angle pipe routing
• 1/4 inch FNPTF thread for pressure-tight thread-sealed connections
• 5,000 psi maximum working pressure rating
• Zinc-plated steel construction for corrosion resistance and durability
• Compact form factor suitable for tight installation spaces

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1/4 inch FNPTF threaded pipe systems in industrial and commercial applications.

Installation Notes

Installation is typically performed by licensed pipefitters or plumbers in accordance with applicable mechanical codes. Shut off and depressurize the line completely before removing or installing any threaded fitting. FNPTF threads are designed to seal at the thread form; apply appropriate thread sealant or PTFE tape per the system fluid compatibility requirements. Do not overtighten, as this can crack the fitting body or damage the seating threads.
