The TIGRE USA INC 36-2059 is a 3-inch PVC-DWV adapter bushing designed to connect Schedule 40 LPS (700 Series) fitting hubs to sewer pipe (400/600 Series) in drain, waste, and vent systems. The spigot x sewer drain hub configuration allows a technician to adapt between two common PVC fitting series without cutting into existing pipe runs. This bushing is made for residential and light commercial drainage applications where mismatched hub sizes create transition challenges. Plumbers and pipefitters rely on this fitting to maintain proper flow alignment in DWV assemblies.
This adapter bushing is suited for residential and commercial DWV installations where a Schedule 40 LPS 700 Series hub must mate with 400 or 600 Series sewer pipe. Typical applications include drain line extensions, sewer lateral connections, and fixture rough-in work. The spigot-to-hub geometry makes it a straightforward drop-in transition piece in both new construction and retrofit drain system repairs.
Designed to adapt Schedule 40 LPS (700 Series) PVC fitting hubs to 400 Series and 600 Series sewer pipe in standard PVC-DWV drain systems.
Installation is performed by licensed plumbers in accordance with the International Plumbing Code (IPC) and local DWV piping requirements. Shut off water flow and verify the pipe is drained before beginning work. Clean and prime both mating surfaces before applying solvent cement, following the cement manufacturer's open time and cure time guidelines. Do not force misaligned fittings — confirm hub and spigot diameters match before cementing.
