Tapered Round Bellows with Cuff End and Flange End

Attach the cuff end with a hose clamp (not included), and screw mount the flange end. Also known as boots, these bellows are often used on CV joints. All are molded, which means they're airtight to keep contaminants out. Air venting may be necessary in fast-cycling applications. Slide these bellows over moving parts, such as rods and shafts.

0.04" to 0.07" Thick Material—0.04″-0.07″ thick bellows are more durable than 0.02″-0.04″ thick bellows, making them good for applications where parts are constantly moving.

Light Duty Round Bellows with Cuff Ends

Thinner than other round bellows with cuff ends, these flexible bellows are meant for light duty applications. All are molded, which means they're airtight to keep contaminants out. Air venting may be necessary in fast-cycling applications. Slide these bellows over moving parts, such as rods and shafts, then secure the cuff ends with hose clamps (not included).

High-Temperature Flat Bellows

These bellows withstand temperatures up to 500° F—more than twice as much as standard flat bellows. Use them to guard flat moving surfaces on machinery. Sewn seams let these bellows breathe, so they retract quickly in fast-cycling applications. The seams will allow small amounts of moisture and dust to pass through.
