3" & 4" DirectVent Pro Chimney Liner Termination Kit (4" X 6 5/8")

The DirectVent Pro 4" x 6-5/8" Co-Linear Adapter is an essential part of a co-linear direct vent installation. Designed to integrate with the DirectVent Pro system, this adapter connects to a chimney liner termination kit that includes both the termination connector and flashing. Components such as the 4"x6-5/8" termination caps, 3" flex liners, and co-linear flex connectors are available separately. For safety and proper performance, the termination kit must be tested and listed for use with each specific appliance—always consult your stove manufacturer’s installation manual for guidance.
