Benefits of Copper Tube

Copper tubing is a strong, long-lasting permanent solution for water systems that by requirement have to be leak proof. Because of the important role of copper tubing, a strong skill set is essential for performing proper installation.

Copper has been utilized as an effective material to supply safe drinking water for hundreds of years due to its resistance to corrosion, pliability, reliability, recyclability, join-ability and safety. Copper is an ageless material as many of competitors to copper are quick to recognize. That in fact isn’t a bad thing at all, because copper has hundreds of years of experience in piping materials for underground water service lines to prove that it’s an effective material. Copper is a prime example of an old product that remains an effective product alongside new and innovative technologies.


Copper tubing and fittings are considered one of the first of lead-free piping materials. Based on today’s standards, all copper alloy used for plumbing mechanisms are required to pass NSF 61 standards for safe drinking water. Now that today’s systems contain no-lead brass valves, fittings and components, solderless joining techniques for copper piping systems exemplify the best option in dependable, long-term, lead-free service line procedures.

Type K Copper

Type K, soft copper tubing, remains free from rusting and is highly resistant to corrosion and scale formation. Type K has a heavy wall thickness for underground service for the water main to house the connection. It is conductive to enable thawing and its flexibility allows it to conform to underground trenching. Type K copper tubing is annealed to toughen and to remove internal stress. It is suitable for use with flared, compression and solder type fittings as long as rounding and sizing are performed.

Benefits of Polyethylene Tube

Polyethylene Tubing has many distinct advantages over other types of service pipe. It will not rust, rot or corrode. It has exceptional toughness, excellent resistance to abrasion and will flex repeatedly without damage. CTS Polyethylene Tubing is offered in various different working pressures.

It’s pressure rating remain unaffected by mild nicks and scratches that may occur during installation. The tubing is resistant to cracking and splitting at sub-zero temperatures. The insulating qualities of polyethylene help to prevent water from freezing inside the tubing. Should freezing occur, thawing should be performed though steam or hot air, not with direct flame.

Stainless Steel Stiffeners

Insert stiffeners are required when compression connections are made to ensure a leak-free installation. When creating a connection using a stiffener and a fitting, it may be necessary to cut the tube back to remove it of any defective pieces.

What is CTS Tubing?

CTS is an acronym that stands for “Copper Tube Size” water tubing. CTS products are typically used for municipal water service systems starting from the water main, leading to a house or building. CTS Tubing CTS is manufactured in accordance with ASTM D2737 standard and is Outside Diameter measured to accept the use of external compression fittings for joining connections. CTS is most often produced in a 250 PSI

Copper Tube Size or CTS tube is frequently referred to as tubing. In nearly every CTS application the pressure rating of the tubing will be a standard 250 PSI. Since the OD is the governing measurement, CTS tubing might also be mentioned as SDR pipe, but nonetheless different than its sister, IPS tubing.

What is IPS Tubing?

ITS Tubing

IPS is an acronym that stands for Iron Pipe Size. For IPS there are multiple ASTM Standards; these are called IPS, ASTM D2239 and ASTM D3035. Here’s the difference between the two: ASTM D2239 is ID measured IPS tubing where the inside diameter remains constant. Meanwhile, the wall thickness increases as the pressure rating increases in accordance with a larger Outside Diameter. ASTM D3035 IPS tubing is OD measured and where the OD remains constant, while the wall thickness expands and the ID decreases as the pressure ratings increase.

After World War II, when homes were being built at a record pace, a safe and reliable means of furnishing water from the main to the house was needed. Black iron, lead and galvanized pipe were no longer the answer, so the water industry turned to flexible copper.

Today, in addition to copper, flexible tubing products, such as polyethylene, enable the supplier to furnish a safe, economical and practical means of bringing water to the home.

We maintain a large supply of tubing products of various lengths and sizes to satisfy our customers' needs.
