Nw Qf Kf And Iso Flange Size Comparison Chart And 49 Off Nw sizes. below are the sizes for the diameters of the various nw, qf, kf and iso vacuum fittings. we have included a file you may download that shows, to scale, the various sizes. this chart also lists the physical measured diameters of the flange so you can use it to review what you have there using a ruler or calipers. Kf flanges, also called qf or nw flanges, are used to form high vacuum connections in 1 2″ (qf10) to 2″ (qf50) diameter vacuum system tubing. kf flanges are sexless, infinitely rotatable, and fastened with quick clamps that compress an elastomer o ring held in a centering ring between two flange faces to create a high vacuum seal. iso kf.
Nw Qf Kf And Iso Flange Size Comparison Chart And 49 Off The four most common flange types are cf (conflat), kf, iso, and asa ansi. for each of these, naming conventions, vacuum ranges, size ranges, and typical applications are discussed. additionally, proper assembly techniques are presented to help the user make consistent and reliable leak free vacuum connections. To seal directly from an lf or lfb style iso flange to these more convenient large qf style flanges. iso quick flange dimensions the iso standard flange interface dimensions are shown on these two pages and are not repeated throughout the catalog. fittings (tees, crosses, elbows, etc.) and adapters, however, have no universal standards. Size. the nw 16, 25, and 40 iso kf rings are installed over the two iso kf flanges. the nw 10 and 50 iso kf rings are installed between the two flange faces. the clamp is installed around all items to secure the assembly (see figures 6 and 6a). for more information, contact customer service at 1 800 345 1967 or 303 449 9861. Kf hv flanges are limited (by the o ring's properties) to applications with temperatures between ~0° c and 120—180° c, and pressure from atmosphere to ~10 8 torr or mbar. the name kf (for klein flansche) was adopted by iso, din, and pneurop standards organizations. it is also called qf, nw, and occasionally, dn.
