4 inch x 2 inch or 1-1/2 inch PVC DWV Saddle Tee

4 Inch x 2 Inch or 1-1/2 Inch PVC DWV Saddle Tee – For Horizontal Drainage Connections

The 4 inch x 2 inch or 1-1/2 inch PVC DWV Saddle Tee is designed to connect smaller diameter branch lines into larger horizontal drain lines without disassembling existing piping. Commonly used in drain, waste, and vent (DWV) applications, this saddle tee enables field-configured tie-ins in both residential and light commercial systems.

Engineering and Performance Characteristics

This fitting is molded from durable, non-metallic PVC and is manufactured to meet applicable plumbing code requirements. It accommodates a secure, solvent-welded or clamped connection onto 4 inch mainlines and provides a reducing branch for either 2 inch or 1-1/2 inch piping, depending on field configuration.

• ✅ DWV Rated Design Built for use in non-pressurized sanitary waste and vent systems.
• ✅ Compatible with Schedule 40 PVC Intended for use with standard wall thickness pipe in DWV applications.
• ✅ Corrosion-Resistant PVC Offers long-term resistance to chemical exposure, biological growth, and moisture degradation.

Specifications

• Material: Polyvinyl Chloride (PVC), white, non-pressure-rated
• Main Size: Fits 4 inch horizontal pipe
• Branch Size: Accepts 2 inch or 1-1/2 inch DWV pipe (field cut or configured)
• Connection Type: Saddle-style solvent weld or mechanical fastening depending on configuration
• Compliance: Conforms to ASTM D2665 and applicable IPC/UPC code sections for DWV systems

Field Applications

This saddle tee is typically installed in gravity-fed horizontal piping to add new branch lines without cutting and refitting pipe segments. It is suited for use in waste arm additions, retrofits, and auxiliary vent tie-ins. Mechanical or solvent weld installation should follow local code guidelines, including minimum branch offset spacing and slope considerations.

Code and Material Notes

PVC DWV fittings like this one are lightweight, low-maintenance, and approved for use in above-ground and limited underground drainage applications. All solvent-welded joints should be made with appropriate primer and cement per ASTM F656 and F493 standards.

The 4 inch x 2 inch or 1-1/2 inch PVC DWV Saddle Tee provides a cost-effective, time-saving solution for drain and vent system modifications, allowing contractors to maintain system flow integrity while making compliant connections in the field.
