🧰 Product Description

A UPVC Reducing Bush 4×3″ is a plumbing fitting designed to connect two pipes of different diameters—specifically, a 4-inch pipe to a 3-inch pipe. The “GM” refers to the brand (AGM, imported from Saudi Arabia), and “SCH 40” indicates Schedule 40, which defines the wall thickness and pressure rating of the fitting.
