Mueller Streamline ABSTRADAPTHSJ112 Abs Dwv Trap Adapter

Product Description

The MUELLER STREAMLINE ABSTRADAPTHSJ112 is a 1-1/2 inch ABS DWV trap adapter fitting designed to connect drain waste and vent piping to a slip-joint trap assembly. Molded from ABS plastic, this fitting features a hub (H) inlet for solvent-welded connections to ABS drain pipe and a slip-joint (SJ) outlet that accepts standard 1-1/2 inch slip-joint trap tubing. It is a standard component in residential and light commercial drain systems, installed by licensed plumbers and qualified pipefitters during new construction or fixture rough-in work.

This trap adapter is used in under-sink drain assemblies for lavatories, kitchen sinks, laundry tubs, and similar plumbing fixtures where a P-trap must transition from a solvent-welded ABS DWV branch line to a slip-joint trap connection. The hub end solvent-welds directly to ABS drain piping, while the slip-joint end accommodates the trap arm or trap tube, allowing for minor angular and length adjustments during final trim-out.

Key Features

• Hub inlet for solvent-weld connection to 1-1/2 inch ABS DWV pipe
• Slip-joint outlet accepts standard 1-1/2 inch trap tubing with slip-joint nut and washer
• ABS plastic construction resists corrosion and chemical exposure in drain service
• Designed for DWV (drain, waste, and vent) applications only — not for pressure service
• Compact profile fits standard under-sink cabinet rough-in clearances

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1-1/2 inch ABS DWV drain systems requiring a hub-to-slip-joint trap adapter transition.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) or the applicable local plumbing code. The hub end requires ABS solvent cement — clean and prime both mating surfaces before applying cement and joining. Shut off the water supply and ensure the drain line is clear before beginning work. The slip-joint outlet requires a slip-joint nut and neoprene washer, which are not included and must be sourced separately.
