AP Products Flexible Air Duct 2" x 25' — Lightweight, Compact HVAC flex hose for tight spaces

The AP Products 013-665 is a 2-inch diameter, 25-foot flexible air duct designed for short-run HVAC and air-conditioning venting tasks.

This lightweight, U.S.-made flex duct provides a compact, flexible pathway for directing conditioned air in tight or temporary installations. Built to fit small-diameter ventilation needs, it’s useful for portable air conditioners, spot cooling, attic fans, and other low-pressure air-handling applications where a narrow, manageable hose is required.

How does the 2" x 25' size handle common installation challenges?

The narrow 2-inch bore is ideal when you must route air through slim openings, conduit knockouts, or between framing members without cutting large access holes. Its 25-foot length allows you to reach remote discharge points while maintaining a continuous, sealed run.

• Small 2" diameter fits through tight wall or panel openings
• 25' length reaches distant outlets without multiple joints
• Flexible construction bends around obstructions for easier routing

Is this flex duct compatible with portable air conditioners and spot ventilation?

Yes — the AP Products 013-665 was made for low-pressure air distribution and pairs well with portable AC units, exhaust fans, and localized ventilation systems. Its lightweight build reduces strain on appliance adapters and keeps connections simple.

• Works with common portable AC exhaust connectors and fittings
• Low mass minimizes sag and stress at attachment points
• Single-piece 25' length lowers the need for extra couplings

What are the construction and packaging details I should know?

This model ships from the United States and comes as a compact, easy-to-store roll that weighs about 2.0 pounds. The packaging dimensions are small enough for convenient handling and storage until installation day.

• Country of origin: United States for traceable sourcing
• Package weight: approximately 2.0 lbs for easy transport
• Package dimensions: compact roll sized for tight storage (approx. 11.176 cm L × 12.7 cm W × 71.882 cm H)

How do I install and maintain this flex duct for best performance?

Installation is straightforward — unroll the duct, route it to the outlet, and secure both ends with appropriate clamps or duct tape rated for HVAC. Routine checks for kinks, sharp bends, or tears keep airflow consistent and reduce pressure losses.

• Use screw clamps or HVAC-rated tape for airtight connections
• Avoid sharp bends that restrict airflow; gentle curves maintain capacity
• Inspect periodically for wear and replace if punctured or degraded

Who is this for: The AP Products 013-665 flex air duct suits homeowners, contractors, and facilities staff who need an affordable, compact solution for routing conditioned air in confined or temporary situations. If you’re working with portable HVAC equipment, performing spot ventilation, or fitting air handling in retrofit projects where larger ducts won’t fit, this lightweight 2" × 25' hose is a practical choice.
