Maggnavac Industries, Inc. carries a complete line of metal sealed knife-edge type of flanges, fittings, hardware, flex couplings, metal hose and accessories. These components are made to industry standards and are completely interchangeable with all other metal sealed Conflat -type flanges. Our flanges are designed to offer superior, leak-free performance in all high and ultra-high vacuum application, and will funcion perfectly to pressures of 1x10(-13) Torr in temperature ranges from -196c to +500c. A seal is effected when bolts tighten these flanges together with a copper gasket between them. The knife edge is forced into the copper. Suitable in all vacuum applications, CF flanges are especially suited to conditions requiring ultra-high vacuum, very clean environments, high temperatures or the containment of toxic, corrosive or radioactive gasses. Maggnavac Industries, Inc. Flanges are manufactured from high quality materials to reduce the possibility of leakage, while maintaining high purity and hardness and reducing pumpdown times in UHV applications. Maggnavac Industries, Inc. offers CF flanges ranging from the mini (1.33OD) up to 16 1/2" O.D., accommodating tubing from 1/4" to 14" diameter.
