2" PVC DWV Coupling – Solvent Weld Fitting for Drainage Applications

The 2" PVC DWV (Drain, Waste, Vent) Coupling is a solvent-welded fitting designed to connect two pieces of schedule 40 PVC pipe in non-pressurized drainage systems. This fitting provides a permanent, rigid joint that maintains flow alignment and structural integrity throughout the piping system.

Manufactured from high-strength polyvinyl chloride (PVC), the coupling offers excellent resistance to corrosion, abrasion, and chemical degradation typically encountered in DWV applications. Its smooth interior surface minimizes flow restriction and reduces the risk of blockage in gravity-fed waste systems.

Contractor-Focused Performance Features

• ✅ Schedule 40 Rated – Suitable for non-pressurized DWV piping per ASTM D2665 specifications.
• ✅ Socket x Socket Configuration – Accepts 2" nominal pipe ends for solvent weld installation.
• ✅ Non-Metallic Construction – Corrosion-proof and ideal for environments where metal fittings may deteriorate.
• ✅ Dimensional Consistency – Molded to tight tolerances for reliable solvent bonding and system alignment.
• ✅ Meets Industry Standards – Certified for use in plumbing systems under UPC and NSF 14 listings.

Installation Guidelines

Install using approved PVC primer and solvent cement according to manufacturer specifications. Pipe ends should be cut square, deburred, and dry-fitted before cement application. Follow appropriate curing times based on temperature and humidity. This coupling is not intended for pressurized applications and should be supported per code to avoid mechanical stress on joints.

Typical Applications

Commonly used in residential and commercial DWV systems for horizontal and vertical transitions. Frequently installed behind walls, beneath slabs, or in crawlspaces where solvent-welded permanent joints are required for drainage continuity.

Code Compliance Insight

DWV fittings such as this coupling are subject to building and plumbing code requirements, including joint type, pipe support intervals, and pipe slope. Proper installation and product selection are essential for inspection approval and long-term system performance.

The 2" PVC DWV Coupling provides a dependable solution for drainage system assembly where consistent sizing, material compatibility, and solvent weld integrity are critical. Its durable construction and standardized design support code-compliant plumbing installations across a wide range of projects.
