OETIKER 16700024 – Stepless Ear Clamp 021.0-706R | Vacuum Systems



The original OETIKER 021.0–706R stepless ear clamp is designed to create a permanent, mechanically strong, and gas-tight connection for hoses and pipes. Thanks to its screwless design, it ensures uniform 360° pressure around the entire circumference of the joint, eliminating local leaks
The clamp is widely used in vacuum technology, particularly in vacuum pumps, where long-term tightness, vibration resistance, and joint stability without the need for subsequent tightening are essential. The stainless steel construction ensures high corrosion resistance and a long service life, even in demanding industrial environments
