Sourcing sewer branch fitting 3/4in x 1/2in 4R (C30400Q35) - plumbing pipe connector

Sourcing sewer branch fitting C30400Q35 sized 3/4in x 1/2in with a 4R configuration is a plumbing pipe connector designed to create a branch in sewer and drainage systems. It connects a main 3/4in run to a 1/2in branch, providing a stable joint between different diameters for residential and light commercial drainage applications. The component is intended for use in gravity drainage and sewer lines where a reliable branch connection is required.

Advantages

The fitting offers a compact solution for transitioning between pipe sizes while maintaining flow integrity and minimizing leakage risk when installed correctly. Its 4R configuration is intended to provide a consistent geometry for joining pipes and simplifies alignment during assembly. The connector is suitable for standard drainage materials and can be integrated into existing sewer pipework without extensive modification.

Suitable for

• Creating a branch from a 3/4in drainage run to a 1/2in outlet
• Residential sewer and drainage installations
• Light commercial drainage systems requiring a size reduction branch
• Repair or modification of existing pipe networks with differing diameters

Key specifications

• Main connection size: 3/4 inch
• Branch connection size: 1/2 inch
• Configuration: 4R branch geometry
• Application: sewer and drainage pipe branching
• Typical installation environment: residential and light commercial

How to use

Select compatible pipe materials and confirm dimensional fit before installation. Prepare pipe ends by cleaning and deburring, then align the main run and branch pipe with the fitting so that connections seat fully. Use the appropriate sealing method for the pipe system (mechanical joint, solvent weld, gasket or other compatible sealing technique) according to local codes and the materials involved. Ensure correct slope and alignment for gravity drainage, then test the joint for leaks after installation.

Usage recommendations

Verify compatibility of the fitting with pipe material and local plumbing codes prior to installation. For gravity sewer applications, maintain required fall and inspect joints after initial water testing. Where abrasion or chemical exposure is likely, choose materials and seals rated for those conditions. If uncertain about the correct sealing method or local regulations, consult a licensed plumber.
