Create-Your-Own Round Bellows with Cuff Ends

Add cuff inserts (sold separately) to these flexible bellows for a custom fit. All are molded, which means they're airtight to keep contaminants out. Air venting may be necessary in fast-cycling applications. To install, slip cuff inserts inside the flange ends of the bellows; slide the bellows over moving parts, such as rods and shafts; then secure the cuff ends with hose clamps (not included).

Create-Your-Own Round Bellows with Flange Ends


Built With Two Mounting Flanges, Two Bellows, One Link, and One Support

Interlock bellows, mounting flanges, and links to create a custom-length bellows. These molded bellows are airtight to keep contaminants out. Air venting may be necessary in fast-cycling applications. Mount these bellows to surfaces with the mounting flanges. Slide them over moving parts, such as rods and shafts.
