Carrier 322055-301 Drain Tube

The Carrier 322055-301 Drain Tube is a critical OEM condensate management component engineered for high-efficiency condensing gas furnaces, specifically within the Carrier 58MCB and Bryant 350MAV product lines. This flexible condensate drain hose transitions liquid effluent from the secondary heat exchanger to the internal trap system, ensuring the combustion process remains unobstructed by moisture buildup. Fabricated from high-grade, chemical-resistant rubber, the 322055-301 is designed to withstand the acidic nature of furnace condensate while maintaining a thermal profile resistant to hardening or cracking over repeated heating cycles. As an authentic HVAC replacement part, it guarantees precise fitment on 5/8-inch barbed fittings, eliminating the risk of bypass leaks that often plague universal aftermarket tubing. Proper installation of this Carrier furnace drain tube is essential for maintaining pressure switch stability and preventing corrosive runoff from damaging the blower deck or burner compartment.

• OEM Precision: Direct factory replacement for Carrier 322055-301 ensures exact length and ID/OD specs for secure clamp seating.
• Corrosion Resistance: Engineered to handle low-pH condensate without degrading, extending the service life of the drainage assembly.
• Optimal Drainage: Smooth internal bore minimizes surface tension and debris accumulation, preventing common furnace drainage issues.
• Vibration Dampening: High-density rubber construction absorbs mechanical resonance, reducing audible noise during inducer motor operation.
• Simplified Maintenance: Designed for rapid swap-outs during annual inspections to maintain system efficiency and prevent water-related safety lockouts.

What causes this drain tube to fail?
Repeated exposure to acidic condensate and high ambient cabinet temperatures can eventually cause the rubber to become brittle or collapse. If the tube is kinked during a previous service, it will likely lead to a pressure switch trip.

Is this tube compatible with all 90% plus efficient furnaces?
No, this is a spec-specific Carrier/Bryant/Payne part. While it fits many models in the 58 and 350 series, you must verify the specific part number in the unit's service manual to ensure proper flow rate and fitment.

Do I need to use specialized clamps for this installation?
For a leak-proof seal, it is recommended to use the original constant-tension spring clamps or equivalent stainless steel worm gear clamps to account for thermal expansion and contraction of the barbed port.
