Flush Bushing 4 in x 3 in

This ABS flush bushing connects a 4 inch hub to a 3 inch spigot in drainage or vent systems. It is manufactured to Schedule 40 dimensions for standard pressure ratings. The fitting suits installers joining dissimilar pipe sizes in a straight run.

Sustained temperature performance

The material is rated for continuous service from minus 40 degrees to 180 degrees Fahrenheit. Cell class 32222 per ASTM D3965 confirms the compound meets defined impact and stiffness requirements. This range supports typical cold-water and hot-water drainage loads without deformation.

Hub x Spigot connection

The hub end receives a 4 inch pipe while the spigot end inserts into a 3 inch fitting. This orientation determines the flow direction and cannot be reversed. Verify the existing pipe ends match this configuration before purchase.
