Breathable Round Bellows with Flange Ends

Slide these bellows over moving parts such as rods and shafts. Sewn seams let them breathe, so they retract quickly in fast-cycling applications. The seams will allow small amounts of moisture and dust to pass through. Screw mount the flange ends to surfaces, or add a mounting flange (sold separately) for stability.

Breathable Round Bellows with Cuff Ends

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. Slide these bellows over moving parts, such as rods and shafts, then secure the cuff ends with hose clamps (not included).

Breathable Wraparound Round Bellows with Flange Ends

No need to disassemble equipment—these bellows wrap around moving parts such as rods and shafts. Sewn seams let them breathe, so they retract quickly in fast-cycling applications. The seams will allow small amounts of moisture and dust to pass through. Screw mount the flange ends to surfaces, or add a mounting flange (sold separately) for stability.

High-Temperature Breathable Round Bellows with Flange Ends

These fiberglass bellows withstand temperatures up to 450° F—about twice as much as standard breathable round bellows with flange ends. They also protect against flames and sparks. Slide these bellows over moving parts such as rods and shafts. Sewn seams let them breathe, so they retract quickly in fast-cycling applications. The seams will allow small amounts of moisture and dust to pass through. Screw mount the flange ends to surfaces, or add a mounting flange (sold separately) for stability.

Wear-Resistant Breathable Round Bellows with Flange Ends

Made of Kevlar, these are the most durable breathable round bellows with flange ends. They also protect against sparks and weld spatter. Slide these bellows over moving parts, such as rods and shafts. Sewn seams let them breathe, so they retract quickly in fast-cycling applications. The seams will allow small amounts of moisture and dust to pass through. Screw mount the flange ends to surfaces, or add a mounting flange (sold separately) for stability.
