3 inch PVC DWV Coupling less Stop Plastic x Plastic

3 inch PVC DWV Slip Coupling – Engineered for Secure Drainage System Connections

The 3 inch PVC DWV Slip Coupling is a critical component in non-pressurized drainage, waste, and vent systems. Designed for joining two sections of 3-inch Schedule 40 DWV pipe, this coupling provides a smooth, permanent connection that ensures structural reliability and long-term leak resistance.

Key Advantages for Professional Applications

• Uniform Wall Thickness – Manufactured to ASTM D2665 specifications for consistent performance across jobsite conditions.
• Straight-Through Flow – Slip-fit hub design maintains proper flow characteristics and reduces the chance of clogging or turbulence in drainage lines.
• Solvent Weld Joint – Designed for chemical bonding with PVC solvent cement, forming a watertight and permanent seal between mating pipes.
• Code-Compliant – Meets or exceeds applicable plumbing code requirements for residential and commercial DWV installations.
• Corrosion and Chemical Resistant – PVC construction is resistant to degradation from household waste, cleaning agents, and environmental exposure.

Specifications

• Material: PVC (Polyvinyl Chloride)
• Size: 3 inch nominal
• End Connections: Slip x Slip (Hub x Hub)
• Standards: ASTM D2665, NSF-DWV certified
• System Type: Drainage, Waste, and Vent (non-pressure)

Installation Guidelines

Installation requires standard PVC tools and materials, including a pipe cutter or saw, deburring tool, primer, and solvent cement. Proper surface preparation and full socket insertion are critical to ensuring structural integrity and leak prevention. This fitting is not intended for hot water or pressurized applications.

Typical Applications

This 3 inch slip coupling is used in horizontal or vertical DWV systems for extending, repairing, or adapting piping runs. It is suitable for concealed or exposed installations in residential, multi-family, or light commercial projects.

Did You Know?

Unlike threaded connections, solvent-welded PVC joints form a fused connection that is less susceptible to mechanical failure or vibration-induced loosening, which is especially important in DWV systems where flow continuity and sealing are critical.

The 3 inch PVC DWV Slip Coupling delivers consistent performance in code-compliant drainage systems. Its precision-molded structure and solvent-weld compatibility make it an essential fitting for professionals seeking long-lasting, dependable DWV solutions.
