Bellow with flanges, L = 750mm, DN25KF, stainless steel 304

Discover our range of high-performance vacuum bellows and hoses, designed to meet the demands of precision, flexibility, and durability in vacuum system design.

🔩 All-Metal Bellows

Our circular corrugated metal bellows are engineered for optimal elasticity and compressive strength. The unique profiling enhances flexibility while maintaining structural integrity.
To ensure a clean finish and eliminate temper colors, we use a vacuum annealing process—baking the bellows at approx. 1040 °C under forming gas. This treatment softens the metal, giving it exceptional flexibility and a polished weld seam.

🔧 Flexible Stainless Steel Bellows

Heat-treated for maximum flexibility, these bellows feature more convolutions than standard models—resulting in lower spring rates and superior movement. Ideal for dynamic vacuum systems requiring frequent motion or vibration absorption.

⚙️ Edge-Welded Bellows

Designed for maximum axial and lateral movement, edge-welded bellows are excellent vibration compensators. Their precision welds and thin-wall construction make them perfect for sensitive applications.

💨 PVC Vacuum Hoses

Looking for a cost-effective solution for rough vacuum lines? Our PVC hoses are lightweight and easy to bend, making them ideal for basic setups. Note: These hoses are not compressible or extendable, but offer reliable performance for low-pressure applications.
