## Description

The MTW MJ20/MJ420 multi-jet water meter uses a polymer body design to allow for low weight and reduced cost but augments the meter with brass threads to reduce the likelihood of stripped threads during installation.

The MTWMJ20/MJ420 may be installed either horizontally or vertically. The MJ420 is for hot water applications.
