Carrier 336835-402 Drain Plug
Maintain the integrity of your residential or commercial HVAC equipment with the Carrier 336835-402 Drain Plug. This genuine Carrier OEM component is engineered specifically for use in condensate management systems, providing a precise seal for secondary or primary drain openings in various air handlers and furnace coils. Constructed from durable, corrosion-resistant plastic, this 0.75-inch drain plug effectively blocks moisture and gas bypass, preventing localized water damage, mold growth, or air leakage within the cabinet. As a direct replacement HVAC part, it ensures a friction-fit seal that stands up to standard system pressures and environmental fluctuations. Professional technicians rely on this drain pan plug to maintain factory specifications during routine maintenance or after flushing the condensate lines. Proper drainage is critical for system longevity; using dedicated condensate drain accessories like the 336835-402 prevents bypass issues that often lead to "nuisance sweating" or electrical shorts in high-humidity environments.
Key Benefits for Technicians:- OEM Compatibility: Specifically designed for Carrier, Bryant, and Payne equipment, including model series 59MN7A, ensure a leak-proof seal without the risk of improper thread pitch.
- Durable Construction: Made from high-grade, non-corrosive material to withstand long-term exposure to acidic condensate.
- Optimized System Efficiency: Prevents air loss through open drain ports, ensuring the blower motor maintains static pressure and design airflow.
- Standardized Fit: 0.75" dimensions allow for easy finger-tightening and removal during seasonal maintenance.
Is this plug a universal fit for all HVAC brands?
No, the Carrier 336835-402 is an OEM part designed specifically for Carrier-family equipment. While it may fit some 3/4-inch ports, verifying the manufacturer cross-reference is recommended for a secure seal.
Should I use pipe dope or Teflon tape on this plug?
Generally, this plug is designed for a secure friction fit or standard threading within plastic condensate pans. Over-tightening with a wrench or adding excessive sealant can crack the pan or the plug.
Why is my drain plug leaking even when tight?
Check for hairline cracks in the secondary drain port or debris within the threads. If the plug is worn or the material has become brittle, replacing it with a new HVAC drain plug is the standard protocol.
