Description

  • The Selkirk Flexi-Liner Type B Gas Vent Aluminum Flexible Chimney Relining Kit is a commercial-grade, multi-component venting solution engineered specifically to safely rehabilitate existing structural masonry or factory-built chimneys serving Category I gas appliances.
  • Fabricated from a highly durable, 2-ply 3003 alloy seamless aluminum core, this rugged 5-inch diameter flexible pipe expands to a full 25 feet with an impressive 5:1 stretch ratio that resists ripping or puncturing over challenging offsets inside tight chimney bends.
  • Rated for intense continuous exhaust temperatures up to 470°F, the turnkey system provides a zero-clearance internal profile while maintaining a permanent, continuous negative static pressure draft to cleanly exhaust carbon monoxide away from furnaces, space boilers, and water heaters.
  • Ideal for mechanical piping contractors, brick masons, and HVAC installers, the 1750025 package arrives compressed inside a suitcase-style carton complete with a ventilation rain cap, roof flashing flange, mortar guard sleeve, and locking tabs to slash onsite labor metrics without requiring complex tool setups.
