Mueller Streamline 6145 Pvc Hub X Hub Stop Coupling 8 in Sch 40

Product Description

The MUELLER STREAMLINE 6145 is an 8-inch PVC hub-by-hub stop coupling engineered for drain, waste, and vent piping systems. Molded from PVC to ASTM D2665, F1866, and F2135 material specifications, it delivers consistent wall thickness of 0.328 inches for reliable, repeatable solvent-weld joints. The stop design positively locates pipe ends, eliminating guesswork during assembly and reducing rework on the jobsite. Licensed plumbers and pipefitters working on residential or commercial DWV rough-in will find the dimensional precision cuts layout and installation time.

This coupling is designed for Schedule 40 dual-marked PVC pipe and belongs to the D Series, a complete line of solvent-weld fittings rated for drain, waste, vent, and air applications. It is suited for interior plumbing rough-in, underground drain runs, and above-ground vent stacks where an in-line, same-size hub connection is required. The 8-inch size targets larger-diameter commercial and multi-family residential drain and waste lines.
