About CTS Flange

Plumbing Flange design and manufacturing, wholesale distribution and installation services to the plumbing and mechanical piping industry for over 50 years. The CTS Copper Flange is an innovative, labor saving and inexpensive method of making anti-electrolysis steel flange connections whenever using copper tube.

Copper Coated Flange

The technology used by CTS in the electrolytic bonding of copper to steel is similar to that used on grounding rod electrodes which have a minimum in-ground life expectancy of 40+ years. This process ensures long lasting molecular bond between the copper layer and the steel flange and eliminates the new to use an EPDM insulator.
