POWERTEC 70140 2-1/2” to 1-1/4” Hose Reducer

This POWERTEC 70140 hose reducer helps connect a 2-1/2 inch OD dust port to a smaller 1-1/4 inch ID dust collection hose or accessory. Its universal, non-threaded, tapered design is compatible with various wet/dry vacuums and dust collection systems. The adapter prioritizes maintaining airflow efficiency when stepping down between hose sizes, making it practical for woodworking and shop vacuums where dust collection performance is critical.
POWERTEC 70136 4″ to 2-1/2″ Cone Reducer

The POWERTEC 70136 cone reducer is a double-sided adapter allowing you to step down from a 4-inch dust collection hose to a 2-1/2 inch hose. This is ideal for fitting larger dust collection setups to smaller shop vacuum accessories. Specifically designed for these hose sizes, it supports a secure fit with common brands like Shop-Vac. However, it’s not designed for direct connection to 2-1/2 inch or 4-inch OD dust ports without an additional flex cuff adapter.

While optimized for handheld tools like sanders and planers, the kit’s flexible hose and adapters offer excellent versatility for multiple woodworking and shop vacuum applications.
Buying Guide for Vacuum Hose Reducers
Choosing the right vacuum hose reducer requires understanding your equipment’s hose sizes and intended applications. Here are key points to consider:
- Compatibility of Hose Sizes: Measure the inner and outer diameters of both your vacuum hose and attachments. Reducers should snugly fit both ends without gaps or requiring excessive force.
- Material Quality: Durable materials like ABS plastic resist impact and corrosion, ensuring long service life and stable connections.
- Design and Fit: Non-threaded tapered designs allow easier installation and maintain airflow efficiency better than threaded or poorly fitted components.
- Application Type: Consider whether you need reducers for wet/dry vacuum hoses, dust collection systems on woodworking tools, or general shop vacuums. Some adapters are specific for certain models or hose diameters.
- Flexibility and Extras: Kits that include multiple size adapters or fitting options provide greater flexibility, especially when integrating older attachments with newer equipment.
- Airflow Efficiency: Good reducers minimize airflow loss to maintain vacuum power. Avoid adapters that create large gaps or significant turbulence, which can reduce suction.
By matching hose reducer size precisely and choosing quality materials with user-friendly designs, you can extend your vacuum system’s versatility and performance with minimal effort.
