One kit seals \u003cstrong\u003eone section joint\u003c\/strong\u003e, so order \u003cstrong\u003eone kit for every joint\u003c\/strong\u003e you open. The kit contains \u003cstrong\u003e3-inch and 6-inch elastomer seals\u003c\/strong\u003e, \u003cstrong\u003etwo pieces of 1\/4-inch rope seal\u003c\/strong\u003e, and a \u003cstrong\u003e2.8-ounce tube of high-temperature silicone\u003c\/strong\u003e; the product photo shows two black elastomer rings, braided white rope, and a tube of \u003cstrong\u003eSIL-BOND\u003c\/strong\u003e silicone with its applicator tip. Weil-McLain distributors list it for the \u003cstrong\u003eEG\u003c\/strong\u003e and \u003cstrong\u003ePEG\u003c\/strong\u003e boilers as well.\u003c\/p\u003e\n\n\u003cp\u003eThe contents trace back to Weil-McLain service bulletin \u003cstrong\u003eSB-1003\u003c\/strong\u003e (July 12, 2010). Cope seal, the \u003cstrong\u003ehigh-temperature rope-type sealing compound\u003c\/strong\u003e once sold by the inch (\u003cstrong\u003e591-641-866\u003c\/strong\u003e), became obsolete in January 2010. Weil-McLain replaced it with \u003cstrong\u003e1\/4-inch rope sold by the piece\u003c\/strong\u003e, \u003cstrong\u003e22.75 inches long (590-735-122)\u003c\/strong\u003e, and the EG\/EGH kit now carries \u003cstrong\u003etwo rope pieces per joint\u003c\/strong\u003e plus silicone. The silicone is also listed by itself as \u003cstrong\u003e513-000-002\u003c\/strong\u003e, a 2.8-ounce tube that covers one section joint. Other boiler families use their own kits: the \u003cstrong\u003e66\/68 combustion chamber kit 386-500-085\u003c\/strong\u003e covers the 66\/68 boilers, and \u003cstrong\u003e386-300-213\u003c\/strong\u003e is the section replacement kit for the \u003cstrong\u003e86\/88\u003c\/strong\u003e, so match the kit to the boiler series.\u003c\/p\u003e\n\n\u003cp\u003eA leaking section joint shows up as \u003cstrong\u003ewater weeping at the seam\u003c\/strong\u003e between sections, rust or mineral tracks running down the casting, \u003cstrong\u003esoot or flue gas at a joint\u003c\/strong\u003e, or a boiler that keeps losing pressure. Find the source first, because a \u003cstrong\u003ecracked section\u003c\/strong\u003e needs a different repair than a failed seal. Replacing the seals means draining the boiler, separating the sections at the joint following Weil-McLain's EG\/EGH manual, \u003cstrong\u003ecleaning both mating surfaces\u003c\/strong\u003e completely, seating the \u003cstrong\u003eelastomer seals\u003c\/strong\u003e, setting the \u003cstrong\u003erope seal\u003c\/strong\u003e with \u003cstrong\u003esilicone\u003c\/strong\u003e, and drawing the sections back together evenly. Refill, \u003cstrong\u003epressure test\u003c\/strong\u003e, and fire the boiler to check that the joint stays dry and tight under heat.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eKey Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eComplete Joint Kit:\u003c\/strong\u003e \u003cstrong\u003eElastomer seals\u003c\/strong\u003e, \u003cstrong\u003erope seal\u003c\/strong\u003e, and \u003cstrong\u003ehigh-temperature silicone\u003c\/strong\u003e in one kit, so nothing has to be sourced separately for the joint.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCurrent Weil-McLain Rope Seal:\u003c\/strong\u003e Built around the rope and silicone Weil-McLain adopted in \u003cstrong\u003eSB-1003\u003c\/strong\u003e to replace the obsolete \u003cstrong\u003ecope seal\u003c\/strong\u003e.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOne Kit Per Joint:\u003c\/strong\u003e Sized for \u003cstrong\u003eone section joint\u003c\/strong\u003e, which makes it simple to order exactly the number of kits the job needs.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOEM Specification:\u003c\/strong\u003e The factory kit for \u003cstrong\u003eEG and EGH\u003c\/strong\u003e boilers, not a generic gasket and sealant assortment.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eCommon Questions\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWhat boilers is it for?\u003c\/strong\u003e The \u003cstrong\u003eWeil-McLain EG and EGH\u003c\/strong\u003e gas boilers (also listed for the \u003cstrong\u003ePEG\u003c\/strong\u003e).
