Parker 3/8 CD45-S 45 Degree Street Elbow Mnptf X Fnptf

Product Description

The PARKER 3/8 CD45-S is a 45-degree street elbow fitting designed for high-pressure industrial pipe systems. It connects using MNPTF x FNPTF threads, combining a 3/8-inch male tapered pipe thread on one end with a 3/8-inch female tapered pipe thread on the other. Constructed from zinc-plated steel, the fitting is rated for a maximum working pressure of 4500 psi, making it suited for demanding fluid and pneumatic applications. Licensed plumbers, pipefitters, and industrial maintenance technicians are the primary installers. The zinc plating provides a layer of corrosion resistance for use in typical shop and plant environments.

This fitting is used in industrial piping systems where a 45-degree directional change is required within a tight space. The street elbow configuration allows it to thread directly into another fitting or port without a nipple in between, reducing overall assembly length. Common applications include compressed air lines, hydraulic systems, oil lines, and general industrial fluid distribution in both shop and facility maintenance settings.

Key Features

• 3/8-inch MNPTF x FNPTF connection type for standard tapered pipe thread compatibility
• Zinc-plated steel construction provides corrosion resistance and mechanical durability
• Meets SAE 140339 standards
• Sold individually — package quantity of 1

Compatibility

Designed as an OEM-style replacement or new-installation fitting for industrial pipe assemblies requiring a 3/8-inch MNPTF x FNPTF 45-degree street elbow connection.

Installation Notes

Installation should be performed by a qualified pipefitter or plumber in accordance with applicable codes. Depressurize and isolate the line completely before removing or installing any fittings. Apply thread sealant or PTFE tape to the male threads per standard practice for tapered pipe thread connections. Do not overtighten — use a properly sized pipe wrench and follow standard torque practices for the pipe size and material.
