Aluminum

This aluminum category includes Schedule 40 pipe nipples for threaded plumbing and fluid-transmission assemblies, along with fire hose leader line wyes for branching compatible hose lines. Commercial installers, maintenance teams, facility buyers, and fire-response crews can use these products to extend pipe connections, join compatible female-threaded components, or route one hose line into two outlets.

Choose Aluminum Connections for Your Piping or Hose Layout

The products represented here serve two distinct connection needs: male NPT pipe nipples for compatible threaded pipe assemblies and leader line wyes for branching compatible fire hose lines. Start by identifying whether the job calls for a straight pipe extension or a hose-line split, then match the stated connection type, size, length, and ordering quantity.

Use Cases

Extend threaded pipe runs

Schedule 40 aluminum pipe nipples join compatible female NPT-threaded fittings, equipment, and pipe components in plumbing and fluid-transfer assemblies.

How to Choose

Match the connection details

For pipe nipples, compare nominal size, nipple length, male NPT ends, and Schedule 40 requirements. For wyes, match the listed NH hose connection sizes and required outlet arrangement.

Applications

Plan straight or branched layouts

Pipe nipples support connection and extension needs in compatible pipe systems. Wyes route one incoming hose line to two outgoing lines for fire hose setups.

Planning Guide

Plan the right fit before choosing

Pipe Nipple Selection

Match male NPT ends to compatible female-threaded components

The pipe nipples shown are Schedule 40 aluminum fittings with male NPT ends on both sides. They are intended for compatible threaded plumbing and fluid-transmission connections.

  • Select the nominal connection size required by the assembly.
  • Choose the needed nipple length, from compact 2-1/2 in. and 3 in. options to 6 in. and 8 in. options shown.
  • Confirm the system calls for a Schedule 40 pipe nipple.
  • Verify that the mating components have compatible female NPT threads.
Hose Wye Selection

Choose the branch arrangement that fits the hose setup

The listed leader line wyes divide a single 2-1/2 in. hose line into two outlet lines. One version has 2-1/2 in. NH connections for the incoming and outgoing lines, while another routes a 2-1/2 in. line to two 1-1/2 in. lines.

  • Match the incoming hose size to the stated 2-1/2 in. NH connection.
  • Choose 2-1/2 in. outlets or two 1-1/2 in. outlets based on the planned line arrangement.
  • Consider the wye with independent ball valves when separate control of each outgoing line is required.
  • The 2-1/2 in. NH two-piece wye has a red painted finish.
