The copper tube/pipe are available in straight lengths and pancake coils. Tubes are ANSI/NSF Standard 61 listed and produced under a Quality Management System which has been approved and registered by recognised quality organisations to the requirements of ISO 9001. Copper water tube, as well as related products and joining methods, must meet stringent standards and specifications for health effects and performance.

ANSI/NSF 61: Drinking Water System Components-Health Effects. This is the health standard for all plumbing products and materials that come in contact with potable water. Copper water tube, copper fittings, and copper and brass plumbing valves and fixtures are covered by NSF Standard 61. The Standard specifies that copper tube be evaluated at a pH of 6.5, rather than at the pH of 5 and 10 for other material types.

ANSI/ASME B16.22: Wrought Copper and Copper Alloy Solder-Joint Pressure Fittings. As its name implies, this specification governs the elbows, tees and other solder-type fittings used to join standard plumbing tube. The copper used in these products has the identical 99.9 percent purity as standard copper water tube.

ASTM B32: Standard Specification for Solder Metal.This specification covers the solders used to join copper tube and fittings. Today's plumbing solder contains no lead.

ASTM B 88: Standard Specification for Seamless Copper Water Tube. This specification covers Copper UNS No. C12200 seamless copper water tube suitable for general plumbing, and similar applications for the conveyance of fluids, and commonly used with solder, flared or compression type fittings. The type of copper water tube suitable for any particular application is determined by the internal or external fluid pressure, by the installation and service conditions and by local requirements. Means of joining or bending are also factors that affect the type of tube to be used.
