Product Identity

The Mueller Industries 1CNX7 is a 2-inch PVC DWV cleanout tee designed for drain, waste and vent systems. It connects two hub ends and a female NPT outlet, providing an access point for maintenance in residential and light commercial plumbing installations.

Standard Constraints

The fitting conforms to ASTM D1784 with a cell class of 12454 and is rated for Schedule 40 service. Maximum operating temperature is 140 degrees Fahrenheit and the component is not rated for pressure applications, limiting its use to gravity-flow drainage only.

Installation Notes

Solvent-weld the hub connections using PVC primer and cement, then thread the cleanout plug into the FNPT branch. Ensure pipes are cut square, deburred and dry-fitted before cementing. Common issues include leaks from insufficient cement coverage, cross-threaded plugs or stress on joints caused by inadequate pipe support.

Questions about this item

Which version of the Mueller Industries 1CNX7 cleanout tee should I choose?

This model is a single 2-inch Hub x Hub x FNPT PVC Schedule 40 fitting in white; there are no alternate sizes or configurations listed for this MPN.

What does the 140-degree maximum temperature mean once the tee is installed in a DWV system?

The fitting is rated for continuous service up to 140 Degrees F, which covers typical residential drain, waste and vent temperatures.

How does the Hub x Hub x FNPT connection standard limit the way this tee is joined to pipe?

Two hub ends accept solvent-welded PVC pipe while the FNPT branch takes a threaded plug or adapter, so the tee can only join to compatible Schedule 40 hub and threaded components.
