1-Y Fittings A Y-shaped pipe fitting that splits one inlet into two outlets to create a branch in piping systems. The design offers a compact, straightforward way to route flow without using multiple elbows. Key benefits - Simple branch connection reduces parts and labor - Space-saving profile fits tight installations - Smooth interior supports reliable flow and predictable performance - Available in common piping materials to suit your system Function and compatibility - Fits standard nominal pipe sizes; check packaging for exact size to match your piping - Suitable for residential and light commercial applications with compatible materials Size and material - Multiple nominal sizes available; confirm size before purchase - Material options depend on model (for example PVC, CPVC, brass, or metal variants) Performance - Designed for steady branch flow within rated pressure and temperature limits per material Use scenarios - Home irrigation: split main line to feed two zones - Plumbing retrofit: add a branch to an existing line without extensive rework - Light commercial systems: route supply to two downstream devices in a compact footprint Note: Verify ratings for your liquid, temperature, and pressure; follow local codes.
