Flexible Drain Hoses

Drain Hoses - Flexibles

The Flexible Drain Hoses category features the tubing used to carry condensate safely away from HVAC equipment in tight, variable or vibration-prone installations. Flexible hoses are ideal for mini-split systems, condensate pumps, air handlers in confined spaces and retrofit situations where rigid PVC is not practical or cannot be aligned easily. These hoses help prevent kinks, maintain smooth flow and allow technicians to work around structural obstacles without compromising drainage.

This section includes corrugated drain hoses, clear vinyl tubing, mini-split drain hoses, pump discharge hoses, insulated hoses and flexible adapters. Most hoses are available in standard HVAC drain sizes like 3/8", 1/2", 5/8" and 3/4" to fit common condensate pump outlets, mini-split ports and auxiliary drain pans. Flexible materials also absorb vibration and help prevent cracking or separation in high-use environments such as attic air handlers or rooftop units.

• Mini-split flexible drain hoses for wall-mounted and cassette units.
• Corrugated hoses for routing through tight paths and bends.
• Vinyl pump discharge hoses for condensate pumps.
• Insulated drain hoses to prevent condensation drip or sweating.
• Flexible adapters for transitions between tubing and PVC systems.

When selecting a flexible hose, confirm inner diameter (ID), wall thickness, temperature rating, flexibility, and whether the line needs to connect to barbed, threaded or PVC fittings. Choose corrugated hoses for complex routing and smooth vinyl hoses for pump discharge lines where pressure and vibration are expected.

Pro tip: Use stainless steel clamps on every barbed connection for leak-proof performance, especially on condensate pump outlets and mini-split drains located in attics or concealed spaces.
