Description

ISO-K ISO-F Vacuum Sealing Flanges SS304 316L with Threaded & Bolted Holes

Product Description

These ISO standard vacuum flanges are manufactured from SS304 and 316L stainless steel, available in ISO-K and ISO-F types, designed specifically for high-performance vacuum sealing and pipeline connection. They are precision machined with bolted or tapped thread holes to ensure strong, stable assembly and reliable sealing in low, medium and high vacuum environments.
The smooth, passivated surface of 304 and 316L provides excellent corrosion resistance, anti‑oxidation and cleanability, making them widely used in vacuum systems, semiconductor equipment, laboratory instruments, coating machines, and vacuum pipeline accessories. The rigid structure and precise dimensional tolerance ensure zero leakage under dynamic and static vacuum conditions, effectively maintaining pressure stability.
ISO‑K and ISO‑F designs support quick installation and disassembly, while bolted and tapped configurations meet different connection and assembly requirements. Compared with ordinary flanges, these vacuum flanges feature higher airtightness, better structural strength, and longer service life under alternating pressure and temperature. Strictly produced under quality control, they are compatible with most vacuum systems and widely recognized in industrial and scientific vacuum applications.
