In some cases this second sealing lip may even act as a substitute for a costly tandem sealing system when complete sealing under certain working conditions can only be achieved by two seals placed one behind the other in separate housing.<br \/>\nIt&#8217;s designed to be less sensitive to pressure fluctuations than typical &#8220;U&#8221; seals.<br \/>\nThe material used to produce this seal is a polyurethane compound that ensures excellent properties on wear-resistance, extended service life and resistance against extrusion.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In this video we present the difference in behaviour of a semi-compact seal and a U-cup seal<\/p>\n","protected":false},"author":5,"featured_media":3695,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[84],"tags":[],"_links":{"self":[{"href":"https:\/\/astonseals.com\/en\/wp-json\/wp\/v2\/posts\/4086"}],"collection":[{"href":"https:\/\/astonseals.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/astonseals.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/astonseals.com\/en\/wp-json\/wp\/v2\/users\/5"}],"replies":[{"embeddable":true,"href":"https:\/\/astonseals.com\/en\/wp-json\/wp\/v2\/comments?post=4086"}],"version-history":[{"count":6,"href":"https:\/\/astonseals.com\/en\/wp-json\/wp\/v2\/posts\/4086\/revisions"}],"predecessor-version":[{"id":6107,"href":"https:\/\/astonseals.com\/en\/wp-json\/wp\/v2\/posts\/4086\/revisions\/6107"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/astonseals.com\/en\/wp-json\/wp\/v2\/media\/3695"}],"wp:attachment":[{"href":"https:\/\/astonseals.com\/en\/wp-json\/wp\/v2\/media?parent=4086"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/astonseals.com\/en\/wp-json\/wp\/v2\/categories?post=4086"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/astonseals.com\/en\/wp-json\/wp\/v2\/tags?post=4086"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
