4" Hub x 2" Spigot PVC DWV Flush Bushing

This white PVC drain component connects a 4 inch hub to a 2 inch spigot in drain waste and vent systems. It is intended for plumbers and contractors who need a flush bushing for non pressure gravity flow piping. The fitting meets ASTM D1784 cell class 12454 material requirements.

Schedule 40 material handles gravity drainage

The fitting is rated for Schedule 40 wall thickness and a maximum temperature of 140 degrees F. It is not rated for pressure applications so it must only be used in vent and drainage lines where pressure does not build. Exceeding the temperature limit or introducing pressure will cause failure.

Hub and spigot ends solvent weld into standard PVC

The hub accepts a 4 inch pipe while the spigot inserts into a 2 inch fitting for a flush transition. Both connections are made with PVC solvent cement creating permanent leak free joints. White colour matches standard PVC pipe for a consistent appearance in exposed installations.

Questions about this item

Will the 4 in hub and 2 in spigot on this Schedule 40 PVC bushing connect cleanly to my existing ABS drain lines?

The bushing is made for PVC DWV systems and meets ASTM D1784 cell class 12454; joining it to ABS requires a listed transition cement approved for both materials.

How can I confirm the joint is sound once the bushing is solvent-welded in place?

After the recommended cure time, run water through the system and inspect the hub and spigot connections for any seepage; the fitting is rated to 140 °F maximum temperature.

Does the package include solvent cement, primer or any transition fittings for dissimilar pipe materials?

Only the white PVC flush bushing is supplied; cement, primer and any required transition couplings must be purchased separately.
