The Carrier KA70PP057 Hose Adapter is a precision-engineered OEM replacement part designed for integration within specific Carrier, Bryant, and Payne HVAC residential systems. This flexible drain adapter is critical for managing condensate runoff, ensuring a leak-proof connection between the primary evaporator coil drain pan and the secondary drainage line. Constructed from high-grade, chemical-resistant PVC-based materials, the KA70PP057 maintains wall integrity under fluctuating temperature cycles and high-humidity conditions common in attic furnace installations. As a specific condensate management solution, this adapter eliminates the risk of bypass leakage that often occurs with generic fittings. For technicians performing preventative system maintenance or 1-for-1 component swaps, this genuine Carrier part ensures ANSI/ASHRAE clearance standards are met. Proper installation involves verifying the barbed or threaded interface dimensions to maintain the necessary condensate drainage pitch and prevent microbial buildup or water damage to the furnace cabinet.

• True OEM Compatibility: Engineered to the exact specifications of Carrier HVAC units, ensuring zero-clearance issues during installation.
• Enhanced Durability: Heat-stabilized construction prevents the adapter from becoming brittle or warping after repeated thermal cycling.
• Rapid Installation: Direct-fit design reduces time spent on the job site by eliminating the need for field-modified drainage configurations.
• Leak Prevention: Precision tolerances ensure a secure seal on the condensate drain port, protecting the electrical components of the cooling system.

Is the Carrier KA70PP057 compatible with all 3/4-inch PVC drain lines?
Yes, this adapter is designed to transition the specific unit port to standard domestic drainage lines, though confirming the Carrier part number against the unit’s service manual is recommended.

Can this adapter be used on both gas furnaces and standalone evaporator coils?
It is primarily utilized in upflow and horizontal furnace applications where condensate management is critical, but technical specifications should be cross-referenced for specific BDP model numbers.

Does this part require specialized adhesive or primer?
Standard PVC primer and cement are typically used for the downstream connection, but the adapter interface itself is designed for a friction-fit or threaded seal depending on the coil drainage port design.
