The NIBCO INC T00090D is a 3/4-inch CPVC 45-degree elbow fitting used to change flow direction at a 45-degree angle in chlorinated polyvinyl chloride piping systems. CPVC construction makes this fitting suitable for hot and cold potable water distribution lines, as well as certain chemical and industrial fluid handling applications. Licensed plumbers and pipefitters install this fitting using solvent cement joining methods standard to CPVC systems. At 0.92 pounds per unit, it is a lightweight, easy-to-handle component suited for both new construction and retrofit work.
This elbow is sized for 3/4-inch CPVC pipe and is sold in packages of 20 units, making it practical for contractors stocking up for residential or light commercial plumbing projects. Common installation scenarios include domestic hot and cold water supply lines, fire suppression branch lines rated for CPVC, and industrial process piping where CPVC chemical resistance is required. The 45-degree angle allows for gradual directional changes that reduce flow restriction compared to 90-degree elbows.
Designed as an OEM-style replacement and new-installation fitting compatible with standard 3/4-inch CPVC pipe and solvent-weld fittings used in residential and light commercial plumbing systems.
Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and ASTM standards for CPVC solvent cementing. Shut off and depressurize the water supply line before cutting and fitting. Use only CPVC-rated primer and solvent cement — do not substitute PVC cement. Allow full cure time per the cement manufacturer instructions before pressurizing the system.
