3 inch ABS DWV Adapter Plastic x Female

3 inch ABS DWV Adapter – Transition Fitting for ABS to PVC Systems

The 3 inch ABS DWV Adapter is designed for joining ABS Schedule 40 drainage piping to compatible PVC systems. This transition fitting is essential in drainage, waste, and vent (DWV) applications where differing plastic piping materials must be connected without compromising code compliance or system performance.

Constructed from impact-resistant ABS thermoplastic, the adapter supports solvent-welded connections on the ABS hub end and mechanical or solvent connections to PVC using an appropriate transition cement. Its dimensional accuracy ensures a tight, stable fit within gravity-fed systems where maintaining alignment and seal integrity is critical.

Technical Specifications

• Size: 3-inch nominal
• Material: ABS Schedule 40
• End Connections: Hub x Spigot
• Application: Transition between ABS and PVC DWV piping
• Compliance: Meets ASTM D2661, D3311; use with appropriate ASTM D3138 solvent cements

Product Highlights

• Material Compatibility: Facilitates connections between ABS and PVC in accordance with plumbing codes
• Form-Stable Under Load: Maintains structural performance in typical DWV system conditions
• Lightweight and Easy to Handle: Reduces strain during overhead or confined installations
• Corrosion-Resistant: ABS material resists degradation from typical DWV system environments
• Code-Recognized Transition: Enables mixed-material joining where allowed by local plumbing codes

Installation Notes

This fitting should be installed using proper solvent welding techniques on the ABS side and an approved transition cement for ABS-to-PVC joints, as per ASTM D3138. Use clean, dry pipe ends, and allow proper cure time before pressure or flow testing. Installation must comply with applicable IPC or UPC code requirements.

Common Applications

• Residential and commercial DWV systems
• Remodeling where existing PVC lines meet new ABS installations
• Underground and above-ground drainage transitions

Important Note:

Not all jurisdictions allow solvent-welded ABS-to-PVC transitions. Always verify with local plumbing codes before use. Where prohibited, a mechanical transition fitting such as a shielded coupling may be required.
