2 inch x 1-1/2 inch x 1-1/2 inch ABS DWV Reducing Sanitary Tee – Hub x Hub x Hub

The 2 inch x 1-1/2 inch x 1-1/2 inch ABS DWV Reducing Sanitary Tee is designed for non-pressurized drain, waste, and vent (DWV) systems. This fitting enables a 90-degree branch line connection with a reduced outlet, commonly used in multi-size pipe layouts. Its solvent-weld hub ends ensure a reliable bond when installed using approved ABS solvent cement.

Application and Material Characteristics

• ✅ Configuration: 2 inch inlet x 1-1/2 inch outlet x 1-1/2 inch side branch – all hub connections
• ✅ Material: Acrylonitrile Butadiene Styrene (ABS), thermoplastic, black
• ✅ System Use: Gravity-fed DWV systems in residential and light commercial installations
• ✅ Flow Design: Swept tee design promotes proper flow direction and venting in accordance with code

Technical Specifications

• Standards: Meets or exceeds ASTM D2665 and CSA B181.1
• Connection Type: Hub x Hub x Hub for solvent-welded joint assembly
• Pressure Rating: Non-pressure system only (gravity drainage)
• Temperature Rating: Serviceable up to 140°F (60°C) intermittent

Installation Requirements

Cut and deburr pipe ends prior to assembly. Apply ABS solvent cement evenly to both mating surfaces and fully insert the pipe into the hub until it bottoms out. Rotate slightly for even distribution. Cure according to manufacturer recommendations before testing or backfilling. This fitting is not suitable for use with PVC pipe or in pressurized systems.

Common Use Cases

• Drainage branches requiring transition from 2-inch to 1-1/2-inch pipe sizes
• Bathroom group waste line connections
• Vertical-to-horizontal drainage offsets in residential rough-in plumbing

Performance and Code Consideration

ABS fittings are widely approved for use in DWV systems due to their impact resistance, thermal stability, and ease of installation. This sanitary tee supports proper flow alignment and venting, essential for maintaining trap seals and minimizing the risk of siphoning in drainage layouts.

The 2 inch x 1-1/2 inch x 1-1/2 inch ABS DWV Reducing Sanitary Tee provides a durable and code-compliant solution for transitioning between drain pipe sizes while maintaining consistent system performance.
