Product details

Mechanical cross with grooved branches provides two additional grooved outlets in existing pipeline, by connecting the pre-set holes at the main pipe surface.

Product Overview

This Mechanical Cross ASTM A536 with grooved branches is used for multi-directional branch line connection on main grooved pipelines in fire protection, water supply and industrial piping systems. It allows on-site tapping and branch installation without cutting the main pipe, featuring convenient construction and reliable sealing. Made of high-strength ductile iron, it provides good pressure resistance and long service life.
