Pipe Fittings Explained: Elbows, Tees, Couplers, Reducers and Valves

Understand common fitting names and what to verify before buying parts for a plumbing or drainage line.

Elbows, tees, couplers, reducers and valves for pipework

Common fitting names

An elbow changes direction; a tee adds a branch; a coupler joins compatible pipe sections; a reducer connects two specified sizes; and a valve controls or isolates flow. Product designs vary, so each part must be checked against the installation plan.

  • Elbow: changes the direction of a pipe run
  • Tee: connects a branch to a main run
  • Coupler: joins compatible pipe sections
  • Reducer: connects components of different specified sizes
  • Valve: controls or isolates flow in a line

Match the fitting to the pipe

Check pipe material, diameter, connection type and the exact fitting named by the installer. Similar-looking products can have different connection methods or intended uses. For repairs, photograph the pipe markings and connection point.

Build a complete materials list

Ask the plumber to list every fitting with quantity and size, including any valves or joining materials. This reduces confusion between similar names and helps the supplier check the complete requirement.

Ask before substituting

If a listed fitting is unavailable, do not substitute by appearance. Ask the plumber or responsible professional to approve an alternative and confirm compatibility.

Frequently asked questions

How do I know which elbow or tee to buy?

Use the fitting type, size and connection method specified by the plumber or project drawing.

Can fittings from different pipe materials be mixed?

Do not assume compatibility. Confirm the joint method and product documentation with the installer.

Can I replace a fitting with one that looks similar?

Check with the installer first. Similar appearance does not confirm the same size, material or connection system.
