The Rock-Vent Pellet Pipe to Flexible Chimney Liner Adapter is used when you need to transition from our 4" pellet pipe to our 4" flexible chimney liner. This is most commonly used when you need to transition from a flexible liner to a pellet vent pipe to pass through a combustible area where reduced clearances is required (Rock-Vent Pellet Pipe has a 1" clearance to combustibles). The flex liner end is female and the pellet pipe end is male.

Note: This adapter connects directly to the flexible liner. It will not connect to a Flexible Chimney Liner Tee Connector or Vertical Connector.
