1-1/2 inch PVC DWV Coupling less Stop Plastic x Plastic

1-1/2 inch PVC Slip Coupling – Schedule 40 Fitting for Solvent Weld Joints

The 1-1/2 inch PVC Slip Coupling is a straight connector used to join two lengths of 1-1/2 inch Schedule 40 PVC pipe with solvent weld (socket) ends. Commonly specified in non-pressurized drain, waste, and vent (DWV) applications, this coupling is manufactured to ASTM D2466 standards and designed for use with piping systems operating below 140°F.

Constructed from rigid polyvinyl chloride (PVC), this fitting provides excellent resistance to corrosion, chemical exposure, and scale buildup. Its slip connections allow for a full-depth socket weld using standard primer and solvent cement, offering a secure, long-lasting bond for gravity-fed and low-pressure systems.

Specifications and Compliance

• ✅ Nominal Size: 1-1/2 inch
• ✅ Material: Schedule 40 PVC (white)
• ✅ Connection Type: Slip x Slip (socket weld ends)
• ✅ Standard: Conforms to ASTM D2466
• ✅ Applications: DWV systems, non-pressure water drainage, venting systems
• ✅ Temperature Rating: Up to 140°F (60°C) in drainage environments

Application Scope

This fitting is commonly used in horizontal or vertical DWV systems where a direct, in-line pipe connection is needed. Ideal for:

• ✅ Gravity-fed residential and commercial drainage
• ✅ Vent stacks and branch lines
• ✅ Repair work requiring inline replacement of pipe sections
• ✅ Non-potable fluid conveyance and utility piping

Installation Recommendations

All joints must be prepared using a compatible primer and solvent cement system per ASTM D2855. Pipes should be cut square, chamfered, cleaned, and fully inserted into the coupling socket to achieve maximum bond strength. Cure times depend on temperature, pipe size, and manufacturer guidelines.

Fitting Advantages

• ✅ Nonmetallic Construction: Will not corrode or conduct electricity, reducing system degradation risk
• ✅ Lightweight: Simplifies handling and alignment in overhead or enclosed installations
• ✅ Chemical Compatibility: Suitable for systems exposed to most household and industrial waste streams
• ✅ Consistent Fit: Socket depth and internal bore tolerances conform to ASTM dimensional standards

Regulatory Compliance

Manufactured in accordance with plumbing code requirements for non-pressure Schedule 40 fittings. Not intended for hot water or pressurized supply lines unless specified otherwise by local jurisdictional standards.

The 1-1/2 inch PVC Slip Coupling is a standard solution for contractors working on DWV piping systems requiring inline connections. Its durability, ease of installation, and dimensional stability make it a reliable component for both new systems and structural pipe modifications.
