Threaded fittings are not the only option available, however. There are fittings that rely on compression, flange, push-to-connect, ORFS (o-ring face seal), or quick couplings.\u00a0<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">Raccords \u00e0 compression<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">A compression fitting relies on a compressible metal material that&#8217;s squeezed into a narrow profile that locks the pipe into position. Compression fittings are preferred in situations where the pipe to be attached cannot be spun, and soldering is difficult or impossible. The pipe is placed inside the compression fitting and a tool is used to squeeze the compression portion of the fitting to crimp the pipe into position forming a reliable seal.\u00a0<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">Connexion par simple pression<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Les raccords \u00e0 connexion rapide sont parfois utilis\u00e9s dans les installations hydrauliques o\u00f9 la simplicit\u00e9 et la rapidit\u00e9 sont primordiales. Ces raccords robustes utilisent un embout femelle conique, souvent muni de barbes et d&#039;un joint torique. Lorsque le tuyau est ins\u00e9r\u00e9 dans le raccord, l&#039;embout femelle, de forme sp\u00e9cifique, le bloque en place, emp\u00eachant son retrait sans d\u00e9verrouiller le syst\u00e8me. Les raccords \u00e0 connexion rapide sont plus co\u00fbteux et, de l&#039;avis de nombreux experts, moins fiables que les raccords filet\u00e9s, mais ils sont rapides et pratiques.\u00a0<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">ORFS<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Un raccord \u00e0 joint torique (ORFS) utilise un joint torique int\u00e9gr\u00e9 \u00e0 la l\u00e8vre du raccord et un filetage pour assurer une \u00e9tanch\u00e9it\u00e9 durable. Ces raccords sont souvent un peu plus co\u00fbteux que les raccords filet\u00e9s, mais offrent une protection sup\u00e9rieure et durable dans de nombreuses applications.\u00a0<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">Raccords rapides<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Les raccords rapides sont faciles \u00e0 connecter et \u00e0 d\u00e9connecter, tout en assurant l&#039;\u00e9tanch\u00e9it\u00e9 gr\u00e2ce \u00e0 la pression exerc\u00e9e sur les parties m\u00e2le et femelle \u00e9vas\u00e9es, chacune \u00e9tant munie d&#039;un joint en caoutchouc ou autre mat\u00e9riau compressible. L&#039;action de connexion comprime le caoutchouc pour former un joint fiable, facilement r\u00e9versible par simple d\u00e9connexion. Ils sont id\u00e9aux pour les applications n\u00e9cessitant des connexions et d\u00e9connexions fr\u00e9quentes, mais leur fiabilit\u00e9 \u00e0 long terme est inf\u00e9rieure \u00e0 celle des raccords filet\u00e9s.\u00a0<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">Conclusion<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">With so many different thread standards used around the world, it&#8217;s important to understand their differences and to know how to identify the standard used on your equipment.
