About Copper Fittings

Copper fittings are one of the most trusted and time-tested solutions in the plumbing industry. Known for their durability, corrosion resistance, and clean appearance, copper pipe fittings are widely used for both hot and cold water plumbing, HVAC systems, and hydronic heating in residential, commercial, and industrial applications.

At Plumbingsell.com, we supply a complete range of copper plumbing fittings online — including elbows, tees, couplings, reducers, adapters, and caps — to help you create secure, long-lasting connections in every type of installation. Whether you’re building a new system or repairing an existing one, our copper tubing fittings deliver leak-free performance and professional results every time.

Understanding Sweat (Solder) Connections

Copper sweat fittings — also known as solder fittings — are joined to copper tubing connectors using a soldering process. When properly done, this method creates a permanent, watertight seal that can withstand high pressure and temperature changes.

To install, the plumber cleans the pipe and fitting surfaces, applies flux (soldering paste), and uses heat to melt lead-free solder around the joint. This process allows the solder to flow into the gap between the pipe and fitting, forming a strong, reliable connection.

Common tools and materials used include:

• Pipe cutter and deburring tool
• Wire brush or abrasive cloth
• Flux and lead-free solder
• Propane or butane torch

This traditional joining method remains a standard choice for professionals who value strength, reliability, and longevity in plumbing systems.

Types of Copper Fittings

Plumbingsell offers a complete selection of copper tubing fittings and copper pipe connectors to suit all installation needs:

• Elbows: Used to change the direction of flow, available in 45° and 90° options. Includes standard elbows (CxC), street elbows (FtgxC), and reducing elbows.
• Couplings & Reducers: Connect two pipe sections. Equal couplings connect same-size pipes, while reducing couplings allow transition between sizes.
• Tees: Split or combine flow. Available in equal tees (CxCxC) and reducing tees for mixed pipe sizes.
• Adapters (Threaded Fittings): Allow transitions from copper to threaded valves or other materials. Includes male (CxM) and female (CxF) threaded adapters.
• Caps and Plugs: Seal line ends. Caps close pipe ends, while plugs seal male fittings.
• Unions: Allow easy system disassembly without cutting pipe, ideal for serviceable installations.

Why Choose Copper Plumbing Fittings

• Long lifespan – Copper systems can last decades with minimal maintenance.
• Corrosion resistance – Ideal for both hot and cold water lines.
• High heat tolerance – Perfect for hydronic or radiant heating systems.
• Easy to inspect and maintain – Unlike plastic systems, copper joints are easy to visually verify.
