1-1/4 inch PVC 45 Degree Hub Elbow

This Schedule 40 PVC fitting joins two pipes at a 45 degree angle using hub connections. It is manufactured to ASTM D1784 cell class 12454 for standard drainage installations. The white elbow handles temperatures up to 140 degrees Fahrenheit. It is not rated for pressure applications.

Suits drainage work needing a white Schedule 40 turn

Plumbers running DWV lines in residential or light commercial buildings will find the hub connection familiar and code compliant. The fitting is unsuitable for pressurised supply lines, hot water above 140 degrees Fahrenheit, or solvent weld systems that require a different connection type.

Check pipe size and connection method before

Verify the existing pipe is 1-1/4 inch nominal diameter and uses a hub or socket joint. Confirm the system operates as non pressure drainage at temperatures below 140 degrees Fahrenheit. Ensure local code accepts ASTM D1784 cell class 12454 PVC for the intended application.
