KF/NW stainless steel vacuum bellows

 EM-Tec stainless vacuum bellows are all-metal flexible vacuum connection hoses for vacuum and high vacuum applications. The bellows are made from 304L stainless steel and they do not out-gas and have very low leak rates. Their construction also reduces vibration between the pump and the vacuum systems. They are ideal for connecting pumps and systems to fixed vacuum lines, with the flexible metal bellows allowing for movement and misalignment. Compression and expansion rates are typically 5-10% of the flexible length. Stainless-steel bellows are a superior alternative to thick-walled PVC vacuum hoses.
