Each of these basic flanges are then offered in weldable formats, prepped for varying smaller tube sizes. Typically, U.S. tube sizes are specified in inches and identified by their outside diameters. MDC standard ISO KF flange size designations are as follows&#8230; K075 for 0.75&#8243;, K100 for 1.00&#8243;, K150 for 1.50&#8243; and K200 for 2.00&#8243; tube diameters. It\u2019s worth mentioning that, with the exception of the centering ring locater diameter, three of the ISO KF flanges depicted in the diagram below, namely NW 10, 20 and 32, are identical to NW 16, 25 and 40 respectively. These latter flanges being the standard for all of MDC\u2019s ISO KF fitted products equipment fitted with NW 10, 20 and 32 flanges can mate them with MDC NW 16, 25 and 40, respectively, by using MDC\u2019s reducer centering ring. The reducer centering ring is constructed with two different size tubular rims or extensions which mate with the respective flange size centering ring locater groove or counterbore.<\/p>\n<p><img class=\"MainLgBodyCopy-img\" src=\"https:\/\/www.mdcvacuum.com\/graphics\/KF_tech_7.gif\" alt=\"\" \/><\/p>\n<\/div>\n<div class=\"col-sm-6\">\n<table class=\"MainBodyCopy\" border=\"1\" width=\"100%\">\n<tbody>\n<tr>\n<td>For product listing, features and specifications click on links below<\/td>\n<\/tr>\n<tr>\n<td>\u00a0NW16 Flange Assembly<\/td>\n<\/tr>\n<tr>\n<td>\u00a0NW16 Flange<\/td>\n<\/tr>\n<tr>\n<td>\u00a0NW25\u00a0 Flange Assembly<\/td>\n<\/tr>\n<tr>\n<td>\u00a0NW25 Flange<\/td>\n<\/tr>\n<tr>\n<td>\u00a0NW40 Flange Assembly<\/td>\n<\/tr>\n<tr>\n<td>\u00a0NW40 Flange<\/td>\n<\/tr>\n<tr>\n<td>\u00a0NW50 Flange Assembly<\/td>\n<\/tr>\n<tr>\n<td>\u00a0NW50 Flange<\/td>\n<\/tr>\n<tr>\n<td>These flanges provide a vacuum mount interface for tube diameters up to 2.00 inches.

For tube diameters above this, Large-Flange&#x2122; ISO LF flanges are used. Kwik-Flange&#x2122; and Large-Flange&#x2122; flanges are part of one and the same family of ISO standard elastomer sealed mounts. Together they provide a complete range of vacuum mounts for 0.75 to 20.0 inch diameter tubes. ISO KF and LF sealing mechanisms are similar but their fastening and clamping methods differ. Due to the wide variation of references used by ISO flange manufacturers, MDC emphasizes the use of the standard ISO NW reference. Note that for all practical purposes, NW and DN references are identical. Large-Flange&#x2122; ISO LF flanges are presented immediately after the Kwik-Flange&#x2122; ISO KF flanges.<\/p>\n<p>In general, MDC components compare with international components using an inch-to millimeter ratio. U.S. sizes refer to a tube\u2019s outside diameter, whereas international sizes refer to a tube\u2019s inside diameter. The chart shown on right gives a quick comparison between inch and metric ISO flange sizes.<\/p>\n<\/div>\n<\/div>\n<br><div class=\"tagcloud\"><a href=\"https:\/\/www.bihec.com\/mdc-vacuum\/tag\/kwik-flange-iso-kf\/\" class=\"tag-cloud-link tag-link-0 tag-link-position-1\" style=\"font-size: 9.2894736842105pt;\" aria-label=\"Kwik-Flange\u2122 ISO KF (13\u4e2a\u9879\u76ee)\">Kwik-Flange\u2122 ISO KF<\/a>\n<a href=\"https:\/\/www.bihec.com\/mdc-vacuum\/tag\/mdc\/\" class=\"tag-cloud-link tag-link-1 tag-link-position-2\" style=\"font-size: 22pt;\" aria-label=\"MDC (68\u4e2a\u9879\u76ee)\">MDC<\/a>\n<a href=\"https:\/\/www.bihec.com\/mdc-vacuum\/tag\/mdcvacuum\/\" class=\"tag-cloud-link tag-link-2 tag-link-position-3\" style=\"font-size: 17.394736842105pt;\" aria-label=\"mdcvacuum (38\u4e2a\u9879\u76ee)\">mdcvacuum<\/a>\n<a href=\"https:\/\/www.bihec.com\/mdc-vacuum\/tag\/%e7%9c%9f%e7%a9%ba\/\" class=\"tag-cloud-link tag-link-3 tag-link-position-4\" style=\"font-size: 17.026315789474pt;\" aria-label=\"\u771f\u7a7a (36\u4e2a\u9879\u76ee)\">\u771f\u7a7a<\/a>\n<a href=\"https:\/\/www.bihec.com\/mdc-vacuum\/tag\/%e7%9c%9f%e7%a9%ba%e6%b3%95%e5%85%b0\/\" class=\"tag-cloud-link tag-link-4 tag-link-position-5\" style=\"font-size: 14.078947368421pt;\" aria-label=\"\u771f\u7a7a\u6cd5\u5170 (25\u4e2a\u9879\u76ee)\">\u771f\u7a7a\u6cd5\u5170<\/a>\n<a href=\"https:\/\/www.bihec.com\/mdc-vacuum\/tag\/%e8%b6%85%e9%ab%98%e7%9c%9f%e7%a9%ba%e6%b3%95%e5%85%b0\/\" class=\"tag-cloud-link tag-link-5 tag-link-position-6\" style=\"font-size: 8pt;\" aria-label=\"\u8d85\u9ad8\u771f\u7a7a\u6cd5\u5170 (11\u4e2a\u9879\u76ee)\">\u8d85\u9ad8\u771f\u7a7a\u6cd5\u5170<\/a><\/div>","protected":false},"excerpt":{"rendered":"<p>Kwik-Flange&#x2122;\u00a0 ISO KF MDC\u2019s Kwik-Flange&#x2122; ISO KF components are an economical  <\/p>\n","protected":false},"author":19,"featured_media":91,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[5],"tags":[61,48,51,56,53,57],"_links":{"self":[{"href":"https:\/\/www.bihec.com\/mdc-vacuum\/wp-json\/wp\/v2\/posts\/90"}],"collection":[{"href":"https:\/\/www.bihec.com\/mdc-vacuum\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.bihec.com\/mdc-vacuum\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.bihec.com\/mdc-vacuum\/wp-json\/wp\/v2\/users\/19"}],"replies":[{"embeddable":true,"href":"https:\/\/www.bihec.com\/mdc-vacuum\/wp-json\/wp\/v2\/comments?post=90"}],"version-history":[{"count":1,"href":"https:\/\/www.bihec.com\/mdc-vacuum\/wp-json\/wp\/v2\/posts\/90\/revisions"}],"predecessor-version":[{"id":92,"href":"https:\/\/www.bihec.com\/mdc-vacuum\/wp-json\/wp\/v2\/posts\/90\/revisions\/92"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.bihec.com\/mdc-vacuum\/wp-json\/wp\/v2\/media\/91"}],"wp:attachment":[{"href":"https:\/\/www.bihec.com\/mdc-vacuum\/wp-json\/wp\/v2\/media?parent=90"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.bihec.com\/mdc-vacuum\/wp-json\/wp\/v2\/categories?post=90"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.bihec.com\/mdc-vacuum\/wp-json\/wp\/v2\/tags?post=90"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
