  • Hub connection fits 3 in pipe without extra couplings
  • ASTM D1784 cell class 12454 confirms material quality
  • White PVC resists corrosion in drain and vent systems

Product Identity

This 3-inch PVC DWV 90-degree vent elbow is a Schedule 40 hub fitting designed for drain, waste and vent piping in residential and light-commercial plumbing systems. It connects to a 3-inch hub to change flow direction in non-pressure gravity drainage lines.

Critical Specification

The fitting is not rated for pressure applications and has a maximum operating temperature of 140 degrees Fahrenheit, so it must only be used in gravity vent and drainage installations. It conforms to ASTM D1784 with a cell class of 12454 for material quality assurance.

Installation Notes

Solvent-weld the hub connection using PVC primer and cement approved for Schedule 40 pipe to ensure a leak-free joint. Common issues include using the fitting on pressurised lines or exceeding the temperature limit, both of which can cause joint failure or deformation.

Questions about this item

What does the 90-degree angle mean when this elbow is installed in a drainage system?

The 90-degree bend changes flow direction by a right angle, connecting a vertical vent stack to a horizontal drain run or joining two perpendicular pipe sections in a DWV system.

How does the Schedule 40 rating and hub connection limit what this fitting can handle?

Schedule 40 sets the wall thickness for standard DWV use, and the hub connection requires solvent welding to 3-inch PVC pipe; the fitting is not rated for pressure applications.

What space and pipe preparation are needed to fit this 3-inch hub elbow?

You need clearance for the 90-degree sweep radius plus the hub depth, and the 3-inch PVC pipe ends must be cut square, deburred, and solvent-cemented into the hub sockets.
