Carrier 4356 Drain Spud

Carrier 4356 Drain Spud

The Carrier 4356 Drain Spud is a critical HVAC condensate drainage component engineered for high-performance moisture management. As a genuine Carrier OEM replacement part, this threaded drain spud ensures a precision seal with the condensate drain pan, preventing the bypass of moisture that can lead to mold accumulation or property damage. Manufactured from high-grade, corrosion-resistant plastic, it is designed to withstand the continuous thermal cycling and chemical exposure typical of residential humidifier and evaporator coil environments. Its 1-inch by 1.25-inch footprint reflects a compact, technician-friendly design for rapid drain assembly installation. This component is cross-referenced for compatibility with several high-efficiency humidifier models, including the P110-LBP and P110-SBP series, ensuring seamless fitment and peak system reliability. By maintaining unrestricted flow, the 4356 protects the internal integrity of the furnace humidifier and broader HVAC system.

Key Benefits:
  • Precision Threading: Engineered for a secure, leak-proof connection to the HVAC drain pan, eliminating risk of secondary water damage.
  • Durable Material: Constructed from robust plastic to resist cracking and degradation in high-moisture refrigeration and cooling applications.
  • Direct Fitment: Serves as an HVAC replacement part for popular Carrier, Bryant, and Payne humidifier models, reducing truck-roll time.
  • Optimized Drainage: Maintains optimal condensate drainage, ensuring the system operates at peak efficiency without overflow risks.
  • Safety Compliance: Meets regulatory standards; California Proposition 65 warning applies for transparent hardware safety.
Common Questions:

Is the Carrier 4356 a universal drain spud?
No, this is a model-specific OEM part. While it fits many Carrier-produced humidifiers, you should verify the threading and diameter against your specific furnace humidifier manual before installation.

What causes a drain spud to fail?
Physical stress from over-tightening or long-term mineral buildup from hard water can damage the threads or body. Replacing a cracked 4356 drain spud immediately is vital to prevent basement or attic flooding.

Can this be used on an evaporator coil pan?
Yes, provided the port dimensions match the 1.25" specifications. It is commonly found in both condensate drain pans and humidifier housing assemblies.
