The catalog designation reads \"Tube Sili \u003cstrong\u003e1\/8 in. ID\u003c\/strong\u003e x 1\/16 in. x 17 in. Red,\" and distributors list it as a \u003cstrong\u003ered silicone\u003c\/strong\u003e \u003cstrong\u003etube\u003c\/strong\u003e of the same size. It is a flexible, heat-tolerant \u003cstrong\u003esilicone line\u003c\/strong\u003e supplied cut to length, so you can fit it to a \u003cstrong\u003ebarb\u003c\/strong\u003e without trimming a long roll.\u003c\/p\u003e\n\n\u003cp\u003eSilicone tubing is used for low-pressure \u003cstrong\u003esense and vent lines\u003c\/strong\u003e because it stays flexible across a wide temperature range and slips over a \u003cstrong\u003ebarb\u003c\/strong\u003e with a snug, sealing fit. Unlike a \u003cstrong\u003evinyl\u003c\/strong\u003e \u003cstrong\u003eline\u003c\/strong\u003e, \u003cstrong\u003esilicone\u003c\/strong\u003e does not harden and crack quickly near warm components. The \u003cstrong\u003eWeil-McLain\u003c\/strong\u003e \u003cstrong\u003e590-317\u003c\/strong\u003e series includes several \u003cstrong\u003esilicone\u003c\/strong\u003e tubes, among them the \u003cstrong\u003e590-317-630\u003c\/strong\u003e, \u003cstrong\u003e590-317-631\u003c\/strong\u003e, \u003cstrong\u003e590-317-632\u003c\/strong\u003e, \u003cstrong\u003e590-317-645\u003c\/strong\u003e and \u003cstrong\u003e590-317-647\u003c\/strong\u003e, so match the length and inside diameter to your original \u003cstrong\u003eline\u003c\/strong\u003e before you order.\u003c\/p\u003e\n\n\u003cp\u003eWhen you replace a \u003cstrong\u003esilicone line\u003c\/strong\u003e, trace the full run first. Look for a \u003cstrong\u003eline\u003c\/strong\u003e that has been \u003cstrong\u003epinched\u003c\/strong\u003e, \u003cstrong\u003ekinked\u003c\/strong\u003e, split at the \u003cstrong\u003ebarb\u003c\/strong\u003e or filled with condensate, because a restricted \u003cstrong\u003esense line\u003c\/strong\u003e can cause nuisance \u003cstrong\u003epressure switch\u003c\/strong\u003e lockouts. Push the new \u003cstrong\u003eline\u003c\/strong\u003e fully onto each \u003cstrong\u003ebarb\u003c\/strong\u003e, and route it with a slight downward slope or a \u003cstrong\u003edrip loop\u003c\/strong\u003e so water cannot sit in a low spot. Do not stretch the \u003cstrong\u003eline\u003c\/strong\u003e tight around a corner. Check each connection by hand after the boiler has run, since \u003cstrong\u003esilicone\u003c\/strong\u003e can relax slightly after the first \u003cstrong\u003eheat cycle\u003c\/strong\u003e. A fresh \u003cstrong\u003eline\u003c\/strong\u003e at every control replacement is an inexpensive way to avoid a repeat visit.
