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.
