Mueller Streamline 429-030 Pvc Schedule 40 Coupling 3 Inch

Product Description

The MUELLER STREAMLINE 429-030 is a Schedule 40 PVC pressure coupling designed for hub-by-hub connections on 3-inch pipe. It is used to join two sections of PVC pipe in potable water, irrigation, and general plumbing pressure systems. The fitting is manufactured from rigid PVC, which provides strong resistance to corrosion and most common chemicals. Plumbers and pipefitters install this coupling in both new construction and repair applications where a reliable, solvent-welded joint is required. The smooth inner wall minimizes turbulence and pressure drop across the connection point.

This coupling is suited for residential and light commercial plumbing installations. Typical applications include cold water supply lines, irrigation mains, and industrial process piping operating within Schedule 40 pressure ratings. The hub-by-hub socket design accepts standard 3-inch PVC pipe on both ends and is solvent-cemented in place per standard installation procedures. It is a direct-fit solution for pressure system work where PVC is the specified pipe material.

Key Features

• Schedule 40 PVC construction for rated pressure performance in standard plumbing and irrigation systems
• Hub-by-hub (socket) connection on both ends accepts 3-inch PVC pipe
• Smooth interior bore reduces pressure drop across the fitting
• PVC material resists corrosion, scale buildup, and a broad range of chemicals
• Lightweight at 0.53 pounds for easy handling during installation

Compatibility

Designed as an OEM-style replacement and new-installation fitting for Schedule 40 PVC pressure piping systems using 3-inch pipe with hub-style solvent-weld connections.

Installation Notes

Installation is performed by licensed plumbers or qualified pipefitters following local plumbing codes and ASTM solvent-cement procedures. Shut off and depressurize the system before cutting into any existing line. Use the correct PVC primer and solvent cement rated for Schedule 40 fittings, and allow full cure time before pressurizing the joint. Do not apply heat or use compression-style tools on this fitting.
