Lukjan RX81121010 Sheet Metal Branch Wye 12x10-10

Product Description

The LUKJAN RX81121010 is a sheet metal branch wye fitting designed for HVAC duct distribution systems. This wye fitting splits a single duct run into two branches, allowing airflow to be directed to multiple zones or registers from one trunk line. Sized at 12x10-10, it connects a 12-inch main duct to two 10-inch branch runs. HVAC installers and sheet metal contractors use this type of fitting during new construction and retrofit duct installations where balanced airflow distribution is required.

This branch wye is suited for residential and light commercial forced-air systems where a main supply trunk must branch into two distribution paths. The 12x10-10 sizing makes it a common choice for trunk-to-branch transitions in central air conditioning, heat pump, and gas furnace duct systems. It is typically installed by licensed HVAC technicians or sheet metal workers as part of a ducted air distribution layout.

Key Features

• Wye branch configuration splits one main duct into two branch runs for balanced airflow distribution
• 12x10-10 sizing connects a 12-inch trunk to dual 10-inch branch outlets
• Sheet metal construction provides durability and compatibility with standard HVAC duct systems
• Designed for use in supply or return air duct networks in forced-air systems

Compatibility

Designed as an OEM-style replacement or new-installation fitting for residential and light commercial HVAC duct systems requiring a 12-inch main to dual 10-inch branch wye transition.

Installation Notes

Installation is typically performed by a licensed HVAC technician or certified sheet metal worker. The system should be powered down and the air handler shut off before making any duct modifications. Secure all connections with appropriate sheet metal screws and seal joints with UL 181-listed foil tape or mastic sealant to prevent air leakage. Follow local mechanical codes and ACCA Manual D guidelines for proper duct sizing and fitting placement.
