Builders Best 110131 Flexible Dryer Vent Duct 4 Inch

Product Description

The BUILDERS BEST 110131 is a semi-rigid flexible duct pipe engineered for residential clothes dryer venting applications. Sold under the Readi Pipe product line, it features factory pre-treated soft cuff ends on both sides that create secure, airtight connections to standard 4 inch dryer vent fittings. The soft cuff design incorporates compression zones and cutouts that allow fast, tool-minimal installation without the need for additional clamps in most setups. At approximately 1 pound, it is lightweight enough for a single technician to handle during rough-in or service calls.

This flexible duct is intended for clothes dryer exhaust venting in residential settings. It bridges the gap between the dryer outlet and the wall or floor vent collar, accommodating minor offsets in the vent path. The semi-rigid construction holds its shape under normal bending while remaining flexible enough to route around framing obstructions. It is commonly installed by HVAC technicians, appliance installers, and experienced DIYers during new construction, appliance replacement, or dryer vent rerouting projects.

Installation Notes

Installation should be performed by a qualified appliance installer or HVAC technician in accordance with local mechanical codes and the dryer manufacturer instructions. Always disconnect the dryer from its power source or gas supply before servicing the vent connection. Keep the duct run as short and straight as possible to maintain adequate airflow and reduce lint accumulation. Do not use sheet metal screws that protrude into the airstream, as they can catch lint and create a fire hazard.
