DWV Coupling for Air and Potable Water

The Mueller Industries Streamline 7072 is a straight copper coupling designed for drain, waste and vent systems handling air or potable water. It joins two 2 in copper tubes with cup connections on both ends and includes a rolled centre stop for consistent insertion depth.

Replaces damaged or undersized straight couplings

The fitting is worth installing when a current joint leaks, fails inspection or cannot meet the 250 Degrees F maximum operating temperature required by the system. It upgrades older joints that lack a positive stop, ensuring reliable alignment without solder migration.

Handles standard residential

The wrot copper construction comfortably manages typical gravity-flow drainage and vent pressures within the rated temperature range. It runs out when system pressure exceeds DWV design limits, when tube diameters differ from 2 in, or when a transition to dissimilar materials is required.

Questions about this item

What copper tube size does the 7072 coupling accept on each end?

Each end fits 2 in copper tube with a 2 1/8 in outer diameter for sweat solder connections.

How is the rolled center stop used during installation?

The stop centers the coupling so both tubes insert to the same depth; a common error is pushing one tube past the stop.

Does the wrot copper material need any periodic replacement?

No, the copper body is rated to 250 Degrees F and does not have a scheduled replacement interval.
