.170" x .250" HDPE Bonded to .250" x .375" HDPE

ECT's Intermittent or skip Bonded tubing is a two-tube bonded configuration. The tubes are color-coded to prevent line crossing and make for easier identification. The durable and lightweight properties all make bonded tubing an ideal choice for a wide spectrum of uses including environmental water sampling, well testing, remediation, and monitoring equipment. ECT's Bonded tubing is the leading choice for bladder pump sample tubing. What is a skip-bond? Also known as an Intermittent Bond, the bond between the two tubes is permanent, but every 6″ there is a 6″ gap where no bond has taken place, thus there is no need for separation or splitting back the tubes wherever a cut is needed. This is ideal when using compression fittings to guarantee a leak proof seal. Also eliminates scrap for cutting different lengths from large spools of bonded tubing.
