Lennox 21N00 is a Schedule 40 PVC DWV 90° street elbow engineered for reliable drainage, waste, and vent piping connections in HVAC and plumbing systems. This fitting features a 3-inch nominal diameter with a hub x spigot (H x Spg) connection, allowing one end to solvent-weld into a hub while the spigot end inserts directly into another fitting or pipe. The 90-degree bend provides an efficient change in direction while maintaining proper airflow and drainage performance.

Manufactured from high-strength PVC, this DWV fitting offers excellent resistance to corrosion, moisture, and chemical exposure commonly found in condensate and drain line applications. The smooth interior wall design helps minimize flow restriction and reduce the risk of buildup, supporting long-term system reliability. Its street elbow configuration is ideal for compact installations where space is limited, reducing the need for additional fittings and simplifying alignment.

Lennox 21N00 is commonly used in HVAC condensate drain lines, residential and light commercial DWV systems, and replacement or repair applications where a durable, code-compliant PVC elbow is required. Designed for straightforward solvent-weld installation, it delivers a secure, leak-resistant connection and dependable performance in both new installations and service work.
