CBS has been supplying for nearly 40 years a variety of industrial, commercial and residential piping, beginning with metallic pipes and, as demand changed, evolving to plastic tubing.

Now CBS has combined the durability and dependability of copper with the corrosion resistance and easy identification of polyethylene. The result is a new series of hybrid products that bring the best of plastic and metallic worlds to the Natural Gas (NG), Liquefied Petroleum Gas (LPG), fuel oil and potable water industries.

GAS GUARD

Gas Guard is a copper (Cu) and polyethylene [(-CH2-CH2-)n] composite tubing developed for Natural Gas (NG) and Liquefied Petroleum Gas (LPG) applications.

Appropriately sized for fuel-gas applications, GAS GUARD is comprised of type L/G soft copper tube that is coated with a continuous seamless layer of yellow polyethylene. The yellow coating is clearly marked, identifying that the tubing contains fuel gas.

Gas Guard may be safely installed in either low pressure (LP) or elevated pressure (EP) distribution Systems.

Coated with extruded polyethylene, Gas Guard is compliant with:

• CSA B149.1-000 Natural Gas and Propane Installation Code
• ANSI Z223.1/NFPA 54 National Fuel-Gas Code for above and below ground installations
• ASTM Standard B88/B837
• UL971
• ULC/ORD-C107.4

PETRO GUARD

Petro Guard is a copper and polyethylene composite tubing developed for fuel oil applications. The orange coating is clearly marked, identifying that the tubing contains fuel oil. PETRO GUARD is comprised of Type ACR refrigeration tube.

Petro Guard meets the requirements for ATM Standard B68/B280 and has been tested and listed to UL 971 and ULC/ORD-C 107.4 Standards.

HYDRO GUARD

Hydro Guard is a copper and polyethylene composite tubing developed for potable water applications. HYDRO GUARD is comprised of Type K/L soft copper tube that is coated with a continuous, seamless layer of red or blue polyethylene, for hot and cold water lines, respectively.

Hydro Guard is listed and certified to NSF 14 and 61 standards and meets the requirements for ASTM Standard B88.
