Nibco CD01650 Pvdf 90 Elbow 1-1/2x1 Inch Sch 80 Fipt

Product Description

The NIBCO CD01650 is a reducing 90-degree elbow fitting manufactured from PVDF (polyvinylidene fluoride), a high-performance thermoplastic suited for demanding chemical and high-purity fluid handling applications. The fitting transitions from a 1-1/2 inch female iron pipe thread (FIPT) inlet to a 1-inch FIPT outlet, allowing a direction change and line reduction in a single component. Rated to Schedule 80 wall thickness, it delivers pressure handling capability well above standard Schedule 40 fittings. Identified by its red color, this fitting is intended for installation by licensed plumbers and pipefitters working in industrial, chemical processing, or high-purity water systems.

This elbow is appropriate for use in systems conveying corrosive chemicals, ultrapure water, or other aggressive media where metal fittings would corrode or contaminate the process fluid. Schedule 80 PVDF fittings are commonly specified in semiconductor fabrication, laboratory plumbing, chemical dosing lines, and commercial water treatment installations. The FIPT x FIPT end connections thread onto male-threaded PVDF, CPVC, or compatible plastic pipe and nipples, making it straightforward to integrate into threaded plastic piping systems.

Key Features

• PVDF construction resists a broad range of acids, bases, and solvents without degradation
• Schedule 80 wall thickness provides elevated pressure rating versus standard Schedule 40
• Reducing geometry transitions from 1-1/2 inch to 1 inch in a single fitting, eliminating a separate bushing
• FIPT x FIPT connections thread directly onto male-threaded plastic pipe or nipples
• Red color provides quick visual identification as PVDF material in multi-material piping systems

Compatibility

Designed as an OEM-style threaded fitting for Schedule 80 PVDF piping systems using 1-1/2 inch and 1-inch female iron pipe thread connections.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter familiar with thermoplastic threaded piping systems. Depressurize and drain the line completely before removing or installing any fitting. Use PTFE thread tape or a thread sealant rated compatible with PVDF and the conveyed media — do not use petroleum-based compounds. Avoid over-tightening threaded PVDF fittings, as the material is subject to stress cracking under excessive torque; hand-tighten plus a controlled additional turn per applicable manufacturer guidance is the standard practice for plastic threaded fittings.
