You are installing a new dryer or relocating one and need a replacement flex duct to meet clearance or length requirements.
-
Existing vent duct is crushed, kinked, restricted or the wrong diameter, causing performance or safety concerns.

Compatibility Notes
-
Suitable for dryers and washer/dryer installations where a 4″ diameter × 8′ flexible ventilation duct is needed.
-
Before ordering:
-
Confirm your dryer’s venting requirements (diameter, length, clearance) and ensure compatibility with a 4″ duct.
-
Verify clamping method, connector type, and whether your installation calls for foil or Proflex type duct (some codes may require rigid or semi-rigid ducting).
-
Note: If the venting system is non-compliant with local building codes (e.g., needs smooth, rigid metal duct), this flexible duct may not be appropriate—consult a technician or code expert.
