If you're having trouble deciding, you're not alone. Here are a few things to consider when trying to decide which type of fittings are most appropriate for your application.</p> <div style="width:250px; background-color:#E6E6E6; padding-top:0px; padding-bottom:0px; padding-left:10px; padding-right:10px; font-size:14px; line-height:21px; float:right; margin-left:25px;"> <p style="padding-bottom:10px; width:200px;">聽</p> <center> <b><a href="http://www.clippard.com/products/fitting-push"><span style="color:#000; text-align: center; font-size:18px;">Push-Quick</span></a></b></center> <ul style="list-style-position: outside; list-style-type: disc; text-align:left; font-size:14px; line-height:21px; padding-bottom:10px; margin-bottom:10px;"> <li> Easier to disconnect</li> <li> Better suited for applications which require frequent connecting/ disconnecting of hoses</li> <li> Usually provide higher flows than equivalent barb fittings</li> <li> Work best with stiffer tubing</li> <li> Measured based on tubing outer diameter (O.D.)</li> </ul> <p>聽</p> <hr color="#fff" size="10" style="position: relative; left:-15px; width:275px; color:#fff; height:10px;" /> <p style="padding-bottom:10px; width:200px;">聽</p> <center> <b><a href="http://www.clippard.com/products/fitting-barb"><span style="color:#000; text-align: center; font-size:18px;">Hose Barb</span></a></b></center> <ul style="list-style-position: outside; list-style-type: disc; text-align:left; font-size:14px; line-height:21px; padding-bottom:10px; margin-bottom:10px;"> <li> Tend to create a better seal</li> <li> More difficult to disconnect</li> <li> Better suited for "low-leak" environments/applications</li> <li> Usually lower cost than equivalent push-quick fittings</li> <li> Work best with softer tubing</li> <li> Measured based on tubing inside diameter (I.D.)</li> </ul> <p>聽</p> </div> <h2> <strong><span style="font-family:arial,helvetica,sans-serif;">Tubing Size</span></strong></h2> <p style="text-align:left; font-size:14px; line-height:21px; width:475px; padding-bottom:10px; padding-left:0px;">The first thing you should consider is your tubing size. <a href="http://www.clippard.com/products/fitting-barb">Barb fittings</a> are measured by tube I.D. (inner diameter), while <a href="http://www.clippard.com/products/fitting-push">push-quick fittings</a> are measured by tube O.D. (outer diameter). If you already have tubing that you are using, be sure to match the tubing to the appropriate fitting for a tight seal.</p> <h2> <strong><span style="font-family:arial,helvetica,sans-serif;">Frequency</span></strong></h2> <p style="text-align:left; font-size:14px; line-height:21px; width:475px; padding-bottom:10px; padding-left:0px;">Next, consider how frequently you will be connecting hoses to the fittings. If you plan to disconnect and reconnect hoses frequently, then <a href="http://www.clippard.com/products/fitting-push">push-quick fittings</a> will make this easier. If you plan to set up your system and leave the hoses attached for several years or longer, <a href="http://www.clippard.com/products/fitting-barb">barb fittings</a> might be a better option.</p> <h2> <strong><span style="font-family:arial,helvetica,sans-serif;">Durometer of Tubing</span></strong></h2> <p style="text-align:left; font-size:14px; line-height:21px; width:475px; padding-bottom:10px; padding-left:0px;">Finally, consider the durometer of your tubing. <a href="http://www.clippard.com/products/fitting-barb">Barb fittings</a> create a better seal on a slightly softer hose, while <a href="http://www.clippard.com/products/fitting-push">push-quick fittings</a> are easier to use with stiffer hose. For example, 星城web recommends using our 85A durometer polyurethane tubing for <a href="http://www.clippard.com/products/fitting-barb">barb fittings</a>, and 95A durometer polyurethane tubing for <a href="http://www.clippard.com/products/fitting-push">push-quick fittings</a>.</p> <p style="text-align:left; font-size:14px; line-height:21px; width:475px; padding-bottom:10px; padding-left:0px;"><a href="http://www.clippard.com/cms/sites/default/files/wiki_images/Fittings_PQ-vs-Barb_700px.png" style="font-size: 12px;"><img alt="Barb Fittings vs. Push-Quick Fittings" src="http://www.clippard.com/cms/sites/default/files/wiki_images/Fittings_PQ-vs-Barb_700px.png" style="width: 350px;" /></a></p> <p style="text-align:left; font-size:14px; line-height:21px; width:475px; padding-bottom:10px; padding-left:0px;">Refer to the charts below for a comparison of flow rates or to view 星城web's tubing recommendations.
