Using 4-Way Pipe Connectors in Plumbing Systems

by | Jun 9, 2023 | News

4-way pipe connectors are multi-joint fittings that connect four pipe sections together at a central junction point. They are commonly used in plumbing, drainage and irrigation applications to merge or split pipe runs.

4-way pipe connectors are available in materials like steel, cast iron, brass and PVC to match different pipe types. Metal 4-way connectors, including galvanized steel and black malleable iron, are often used with threaded metal pipe like galvanized steel, black iron and cast iron.

Common Applications For 4-way Pipe Connectors Include:

  • Connecting four drainage pipes to a main soil stack in a multi-story building.
  • Merging supply lines to a main water line or a sprinkler system manifold.
  • Joining multiple vent pipes to a main vent stack.
  • Combining gas lines to a single supply.

4-way Metal Pipe Connectors With Threaded Or No-hub

4-way metal pipe connectors are available in threaded or no-hub versions. Threaded 4-way fittings thread directly onto metal pipes using tapered pipe threads. They are available in various sizes from 1.5 inches to 6 inches in diameter.

No-hub 4-way connectors have a bell-shaped opening that the plain end of pipe slides into. They are sealed using compression gaskets and clamps. These fittings are common for cast iron drainage systems.

4-way Metal Fittings Materials – Galvanized steel & Black Malleable Iron

Both galvanized steel and black malleable iron are suitable materials for 4-way metal fittings. Galvanized fittings are usually used for water and gas lines while black fittings work best for drainage applications.

Using high quality fittings along with proper installation practices like cleaning pipe ends, applying threading compound and tightening securely helps ensure 4-way pipe connectors form reliable, leak-proof connections between multiple piping runs.
