What Is a Copper Pipe Fitting?
Copper tubing, known for its excellent workability and corrosion resistance, is commonly used in household plumbing.
Copper pipe fittings are specialized connectors for copper pipes, available in several types. For copper pipes, soldering or brazing is a common method for joining, which involves low-temperature techniques to connect pipes.
Other fitting types include one-touch fittings that easily join by inserting copper pipes, and screw-tightened fittings.
Uses of Copper Pipe Fittings
Copper is economical, offering corrosion resistance and workability at a low cost. It’s widely used in residential water supply, hot water systems, and in medical and air conditioning applications.
For water supply, copper may leach from pipes. Thus, some pipes are tin-coated to prevent leaching. Copper pipe fittings are essential for extending and branching copper piping, with the most suitable type chosen based on cost and application.
Principle of Copper Pipe Fittings
While stainless steel is more durable, copper piping offers a cost-effective and durable alternative. PVC piping, though low-cost, is less durable, particularly in narrower diameters where it’s prone to breakage. Copper strikes a balance between cost and durability.
Fittings connected by solder are brazed, with a simple design. The solder’s tin creates an alloy with copper, facilitating connections. Brazing requires a torch and skill, as it can’t be done near flammable materials.
Screw-tightened and plug-in fittings offer convenient alternatives. The copper pipe simply inserts into the fitting, and an O-ring seals the joint, preventing leaks when matched correctly in size.
