Applications
Swagelok FM Series braided metal hoses are used in vacuum systems, high-purity gas distribution, and process lines handling corrosive or reactive media. The stainless steel construction and metal braid make them well suited for high-temperature vacuum applications, semiconductor process gas lines, research vacuum chambers, and any plumbing run where polymer hoses would be unsuitable due to permeation, outgassing, or chemical compatibility concerns. The Swagelok tube fitting ends allow tool-free connection to standard Swagelok tubing and fittings, making these a common choice in laboratory and industrial vacuum systems as well as inert and corrosive gas handling lines. The 1/4-inch tube fitting size is one of the most widely used sizes in lab-scale and pilot-scale vacuum and gas systems.
This Swagelok SS-FM4SL4SL4-23 FM Series stainless steel braided hose pair is in used condition. Both hoses were pulled from a working vacuum or process gas system. The stainless braid is intact on both hoses with no visible kinks or damage. The 1/4-inch Swagelok tube fitting ends show light surface oxidation and some residue consistent with normal service use — visible in the close-up photos. The fittings appear structurally sound with thread engagement surfaces intact. Overall, the hoses present well for continued use. Please view our photo set and contact us if you have any questions.
