2 inch PVC DWV Coupling less Stop Plastic x Plastic

Schedule 40 PVC Slip Coupling – Socket x Socket Connector for Pressure and DWV Systems

The Schedule 40 PVC Slip Coupling is a socket x socket fitting designed to join two plain-end PVC pipes of the same nominal diameter. Manufactured from rigid polyvinyl chloride (PVC) in accordance with ASTM D2466, this coupling is intended for use in cold-water pressure applications, irrigation systems, and non-pressurized drain, waste, and vent (DWV) piping.

Its slip-fit configuration allows for solvent welding, providing a permanent, pressure-tight bond without threaded engagement. The coupling's smooth interior and consistent wall thickness help maintain flow characteristics and system integrity across a wide range of operating conditions.

Product Features

• ✅ Socket x Socket Ends Accepts standard Schedule 40 PVC pipe for direct solvent weld installation.
• ✅ High-Strength Construction Molded from durable Type I, Grade I PVC conforming to ASTM D1784 for dimensional stability and long-term mechanical performance.
• ✅ Corrosion and Chemical Resistance Inert to most acids, bases, salts, and organic compounds commonly encountered in plumbing and industrial systems.
• ✅ Non-Conductive Material Suitable for electrical isolation and dielectric use cases where metallic fittings are not acceptable.
• ✅ NSF Certified Approved for potable water service under NSF/ANSI 61 and NSF 14 (if applicable).

Technical Specifications

• Material: PVC (polyvinyl chloride)
• Nominal Size: Varies by selection (e.g., 1/2 inch, 3/4 inch, 1 inch)
• Connection Type: Slip x Slip (solvent weld)
• Applicable Standards: ASTM D2466, ASTM D1784, NSF/ANSI 61 (potable applications)
• Pressure Rating: Up to 450 PSI at 73°F (dependent on pipe size and system configuration)

Installation Guidelines

Surfaces must be clean, dry, and free of debris prior to solvent welding. Use a compatible PVC primer and solvent cement in accordance with ASTM D2855. Insert pipe fully into the socket with a quarter-turn motion to ensure uniform distribution of cement. Allow adequate cure time based on ambient temperature and pipe size before pressurizing the system.

Common Applications

Slip couplings are widely used in potable water lines, irrigation systems, chemical conveyance, and DWV piping. Suitable for both horizontal and vertical configurations in residential, commercial, and light industrial installations.

System Design Note

PVC fittings should not be used in hot water systems unless rated for CPVC. Use within pressure and temperature limits specified by the manufacturer and follow local plumbing codes for material approvals and installation practices.

The Schedule 40 PVC Slip Coupling offers a solvent-welded, corrosion-resistant connection point for high-integrity plastic piping systems. Built to standard dimensional tolerances, it provides consistent performance across a variety of plumbing and mechanical applications.
