Mueller Streamline 6376 Pvc Dwv Trap Adapter 1-1/2 in Hub X Slip

Product Description

The MUELLER STREAMLINE 6376 is a PVC DWV Desanco trap adapter fitting designed for drain, waste, and vent piping systems in residential and light commercial plumbing applications. This straight female adapter transitions from a 1-1/2 inch hub connection to a 1-1/2 inch slip joint, allowing a standard P-trap or drain arm to connect cleanly to a DWV hub fitting. It ships with a chrome nut and washer for a finished appearance at the slip joint connection. The PVC construction resists common drain chemicals and corrosion, and smooth interior walls maintain unobstructed flow through the fitting.

This fitting is used wherever a P-trap or sink drain arm must connect to a DWV hub in a wall or floor stub-out. Typical installations include kitchen sinks, bathroom lavatories, and utility sinks. It meets NSF 14 and UPC standards and conforms to ASTM D2665, F1498, D331, and D1784 material specifications, making it suitable for chemical-resistant and corrosion-resistant drain applications as well as standard DWV service.

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1-1/2 inch PVC DWV drain systems requiring a hub x slip joint trap adapter connection.

Installation Notes

Installation is performed by a licensed plumber in accordance with the International Plumbing Code and applicable local codes. Shut off the water supply and ensure the drain system is depressurized before beginning work. The hub side is solvent-welded to the DWV piping using approved PVC primer and cement; do not use solvent cement on the slip joint side. The chrome nut and washer are hand-tightened onto the slip joint connection — avoid over-tightening, which can crack the nut or distort the fitting.
