2" Hub PVC DWV Socket Cap

This white PVC socket cap fits a two-inch hub connection in drain, waste and vent systems. It is made to Schedule 40 dimensions and meets ASTM D1784 cell class 12454. The fitting is not rated for pressure applications. It suits installers closing off unused hub openings in non-pressurised plumbing.

Temperature and pressure limits

The cap withstands a maximum temperature of 140 degrees Fahrenheit. It carries no pressure rating and must not be used in pressurised lines. These limits define where the fitting can be safely installed in a drainage network.

Schedule 40 PVC hub connection

The single deciding specification is the two-inch hub size combined with Schedule 40 PVC construction. Match this to the pipe hub you are capping; a different diameter or schedule will not seal correctly.

Questions about this item

Should I choose the 2-inch hub cap or a different pipe size?

The 1WKK7 is a 2-inch hub socket cap; select it only when your DWV line is exactly 2 inches, otherwise match the cap to the pipe diameter you are joining.

What does the 140-degree Fahrenheit rating mean once the cap is installed in a drain line?

The PVC material is rated for continuous service up to 140 Degrees F, so it will handle typical residential drain temperatures without softening or deforming.

How does the Schedule 40 hub connection limit what I can join to this cap?

The hub is manufactured to Schedule 40 dimensions and ASTM D1784 cell class 12454, so it accepts only Schedule 40 PVC pipe with a matching 2-inch hub socket.
