Mueller Streamline 5966 Pvc Dwv Hub Slip Coupling 2 in

Product Description

The MUELLER STREAMLINE 5966 is a 2-inch PVC DWV hub slip coupling designed for drain, waste, and vent piping systems. This repair-style, straight coupling uses a hub-by-hub end connection, allowing plumbers to join or repair sections of 2-inch PVC DWV pipe without cutting into fittings on either end. Manufactured to ASTM D2665, F1498, D331, and D1784 material specifications, it delivers consistent dimensional integrity for a reliable, leak-resistant fit. Smooth interior walls reduce scaling buildup and support unrestricted flow through the drain line.

This coupling is suited for residential and light commercial drain, waste, and vent applications where PVC is the approved piping material. It is also rated for chemical and corrosion-resistant installations, making it appropriate in environments where standard metal fittings would degrade. Licensed plumbers and pipefitters use this fitting during repair work when a damaged section of DWV pipe needs to be spliced without disturbing adjacent fittings. Its straight, slip-style design simplifies alignment during assembly.

Key Features

• Hub-by-hub end connection suits repair and splice installations on existing DWV runs
• PVC construction resists chemicals and corrosion for long service life in drain applications
• Smooth interior walls minimize scaling and maintain free flow through the fitting
• Meets NSF 14 and UPC standards for potable-adjacent and drain system installations
• Manufactured to ASTM D2665, F1498, D331, and D1784 material specifications
• Consistent dimensional tolerances ensure proper fit with standard 2-inch PVC DWV pipe and fittings

Compatibility

Designed as an OEM-style replacement and repair coupling for standard 2-inch PVC DWV drain, waste, and vent piping systems meeting ASTM D2665 and F1498 specifications.

Installation Notes

Installation of this fitting is typically performed by a licensed plumber in compliance with the International Plumbing Code (IPC) and local jurisdictional requirements. Shut off any water supply and verify the drain line is empty and dry before cutting into the existing pipe. Solvent-cement joining requires a compatible PVC primer and cement applied per manufacturer instructions and ASTM standards. Allow adequate cure time before restoring flow through the line.
