Drain Fittings & Elbows

Elbows & Drain Fittings

The Drain Fittings & Elbows category contains the essential PVC connectors, directional changes, adapters and junction fittings used to route, extend and transition HVAC condensate drain lines. Proper drainage layout is a critical part of preventing water backups, pan overflows and long-term moisture damage. High-quality fittings help maintain a smooth, unrestricted flow path from the unit drain pan to the final discharge location—whether the run is short and simple or spans multiple structural obstacles.

This section includes standard 90° and 45° elbows, condensate tees, wyes, couplings, slip adapters, reducing fittings, barbed connectors and line transition components. These parts support everything from air handlers and coils to mini-split drain lines and high-efficiency furnace condensate systems. Many fittings are designed to work with both rigid PVC and flexible condensate tubing, giving technicians the freedom to choose the most practical route on retrofit or tight-space installations. Smooth interior walls and proper sizing ensure minimal resistance and help reduce clog formation.

• 90° & 45° elbows for directional changes in drain lines.
• Condensate tees & wyes for equipment with multiple drain outlets.
• Slip couplings & unions for extensions and service access.
• Reducers & adapters for transitions between line sizes.
• Barbed fittings for mini-split and flexible tubing connections.

When selecting drain fittings, confirm compatibility with PVC schedule, line diameter, condensate tubing size and the required turning radius. High-static equipment or long horizontal runs may require smoother fittings to prevent turbulence. Always maintain proper slope and ensure fittings are installed in accessible areas whenever possible to simplify seasonal cleaning.

Pro tip: When routing through tight or concealed spaces, use long-sweep elbows instead of sharp 90° turns to improve flow and reduce clog risk. Pair tees with accessible cleanout ports near the air handler to make flushing the drain line faster during routine maintenance.
