Copper Tubing (Rigid, Soft & Refrigeration):

  1. Type M has an even thinner pipe wall section, and is used in residential and commercial water supply and pressure applications. In the United States it usually has red colored printing.

  2. Type L has a thinner pipe wall section, and is used in residential and commercial water supply and pressure applications. In the United States it usually has blue colored printing.

  3. Type K has the thickest wall section of the three types of pressure rated tubing and is commonly used for deep underground burial such as under sidewalks and streets, with a suitable corrosion protection coating or continuous polyethylene sleeve as required by code. In the United States it usually has green colored printing.

  4. Type DWV has the thinnest wall section, and is generally only suitable for unpressurized applications, such as drains, waste and vent (DWV) lines. In the United States it usually has yellow or light orange colored printing, common sizes being 1-¼" , 1-½", and 2" copper tube size.

  5. Type ACR is used in air conditioning and refrigeration is designated ACR. It is sized by the actual outside diameter and comes in lengths of 20 feet in hard temper and coils of 50 feet in soft temper

  6. Refrigerant Line Sets consist of two semi-flexible copper pipes to connect the outdoor air conditioner or heat pump to the indoor evaporator coil. The smaller pipe is called the liquid line. The larger pipe is referred to as the suction line, and can be purchase with or without insulation.

PVC Schedule 40 DWV Tubing

  • PVC Schedule 40 is highly durable, with high tensile and impact strength. It is easy to install and has better sound deadening qualities than PVC Schedule 40 DWV Foam Core. Installation requires the use of primer and solvent cement.

CPVC Tubing

  • CPVC shares most of the features and properties of PVC.CPVC can withstand corrosive water at temperatures greater than PVC, typically 40°C to 50°C (104°F to 122°F) or higher, contributing to its popularity as a material for water piping systems in residential as well as commercial construction.

Pex Tubing

  • Pex is used predominantly in building services pipework systems, hydronic radiant heating and cooling systems, domestic water piping, and even insulation for high tension (high voltage) electrical cables.

 

Black & Galvanized Pipe 

Black Pipe

  • Black pipes are more commonly used in homes and businesses. They are also called steel pipes and are used to carry water and gas inside homes and offices. These pipes have a high resistance to fire and heat which is why they are also used for fire sprinklers. For this very reason they are also used where heating and cooling water is carried. Gas lines are mainly constructed using black pipes, and even appliances are connected with the supply lines using these black pipes. It is easy to join using either mechanical couplings or by using arc welding. Black pipe can even be used to carry water but it should not be drinking water.

 
 

Galvanized Pipe

  • For the supply of water, it is galvanized pipe that is mainly used. It is in reality a steel pipe that has a coating of zinc. Addition of zinc makes the pipe more durable and also increases resistance to corrosion. It also ensures there are no mineral deposits in the pipeline. Since the invention of galvanized pipes 30 years ago, they are being increasingly used all over the world. Galvanized pipe has a property that zinc begins to flake after some time. This is why it is not suitable for carrying gas as this zinc causes the pipeline to choke. It is very durable and lasts for more than 40 years which is why it is extensively used as railings, scaffolding and in all other construction projects. Galvanized pipes are more expensive than black pipes. There is also the fact that it corrodes quicker than copper pipes. One drawback of galvanized pipes is that flaking of zinc sometimes causes the pipe to burst.

Coated Gas Connectors

  • Deep corrugations enhance flexibility, making installation easier.

  • May be used with natural, manufactured, mixed and liquefied petroleum (LP or propane) gases and LP gas-air mixtures. Internal pressures up to 1/2 PSI.

  • Available in 12, 24, 36, 48, 60, and 72 inch

Dormont Gas Connectors

  • Stocking 1/2 & 3/4. Ideal for the food service industry.

  • These gas connectors are 304 stainless steel corrugated tube covered with a tight weave stainless steel braid. The outside hose coating is an antimicrobial PVC coating that inhibits growth of bacteria, mold and mildew on the connector. Rotational technology fittings on both ends of the connector rotate 360 degrees, greatly reducing stress at both connector ends.

Cast Iron Pipe

Cast Iron is the premier piping material for sanitary and storm drain, waste, and vent applications. It has been used in these applications for hundreds of years and is for non-pressure applications where temperatures will not exceed 212° F.

It is the most durable DWV piping system available and can be used in all types of construction. It has high crush strength, is noncombustible, and offers superior sound-deadening performance.
