Is POWERTEC Flex Cuff Coupler the straightforward fix for leaky joints and fiddly fittings?
⚡ At a Glance
- • Seal Quality: Flexible rubber conforming to fittings for an airtight connection
- • Best for: Home workshops and small commercial dust collection systems using 4 inch ports
- • Not ideal for: Systems that require custom-sized or rigid metal couplings
Six reusable rubber cuff couplers include steel hose clamps for secure fastening. Dimensions match 4 inch nominal outer diameter dust collection ports for straightforward connections.
Airtight connections - with flexible rubber cuff construction
Durable rubber construction flexes to accommodate slight diameter differences while forming a sealed join between two 4 inch OD ports. Steel hose clamps secure the cuff around fittings to hold the seal in place.
A tight, leak-resistant joint reduces dust escape and keeps extraction performing efficiently. Quick containment of dust helps maintain a cleaner workshop and reduces filter loading on collectors.
Fast installation and removal - thanks to reusable cuff design with clamps
Reusable cuffs slip over adapter ends and compress with supplied steel clamps, eliminating the need for screws, adhesives or duct tape. The design supports repeated removal and refitting without damaging the rubber.
Switching tools or reconfiguring duct runs becomes quicker and less messy. Reduced reliance on temporary fixes keeps joints consistent and saves time during setup changes.
Durable fit for regular use - with robust materials and compact dimensions
Manufactured from heavy-duty rubber to withstand repeated installation and normal workshop wear, the cuff measures 4 inches internal diameter, 4-9/16 inches outer diameter and 2-9/16 inches length. Steel clamps add mechanical strength to the connection.
Long-lasting materials minimise replacements and keep maintenance frequencies low. Compact length suits tight duct layouts without sacrificing grip or sealing performance.
