Parker 1 CD45-S 45 Degree Street Elbow 1 in Mnptf Fnptf

Product Description

The PARKER 1 CD45-S is a 45-degree street elbow fitting designed for industrial pipe systems requiring directional changes in tight spaces. It connects male NPT tapered (MNPTF) threads on one end to female NPT tapered (FNPTF) threads on the other, allowing a single fitting to serve as both a connector and a directional offset. Constructed from zinc-plated steel, it handles a maximum working pressure of 1,800 psi. This fitting is installed by licensed plumbers, pipefitters, and HVAC-R technicians in hydraulic, pneumatic, and fluid-transfer applications where a standard elbow and a nipple would otherwise be required.

This street elbow is suited for industrial and commercial pipe assemblies where space constraints make a standard elbow impractical. The street configuration eliminates the need for a close nipple between fittings, reducing overall assembly length and potential leak points. Typical install scenarios include compressed air lines, hydraulic supply lines, and general industrial plumbing systems operating at elevated pressures. Both thread connections are 1 inch, making this a straight-size fitting with no reduction.

Key Features

• 45-degree street elbow configuration combines directional change and male-to-female thread transition in one fitting
• Rated to 1,800 psi maximum working pressure for demanding industrial service
• Zinc-plated steel construction provides corrosion resistance in typical shop and mechanical-room environments
• MNPTF x FNPTF connection type ensures tapered thread engagement and reliable seeal without additional adapters
• 1 inch on both ends — no reduction, no bushing required
• Compact street design reduces overall assembly length compared to standard elbow plus nipple combinations

Compatibility

Designed as an OEM-style replacement or new-installation fitting for industrial pipe assemblies using 1-inch NPT tapered threaded connections at working pressures up to 1,800 psi.

Installation Notes

Installation should be performed by a qualified pipefitter or licensed plumber in accordance with applicable mechanical and plumbing codes. Depressurize and isolate the line completely before removing or installing any threaded pipe fitting. Apply thread sealant or PTFE tape appropriate for the service medium to the male threads before assembly. Do not over-torque; thread engagement should be wrench-tight using a properly sized pipe wrench with a backup wrench on adjacent fittings to avoid stressing downstream connections.
