Applied directly to surfaces adjacent to the work area, it absorbs and dissipates heat before it can damage rubber seals, plastic fittings, or other heat-sensitive materials. A built-in heat transfer color indicator changes the paste from dark blue to light blue as it absorbs heat, giving technicians a visual cue of thermal load during the repair. The compound is non-toxic, asbestos-free, odorless, and safe for skin contact. Cleanup requires nothing more than a cloth wipe or water rinse, and it leaves no staining residue.\u003c\/p\u003e\n\u003cp\u003eThis paste is used in HVAC, refrigeration, and plumbing applications wherever brazing or soldering must occur near valves or seals that cannot tolerate high heat. Typical use cases include work on ball valves, solenoid valves, and reversing valves where the valve body or adjacent sealing components sit close to the torch path. It applies directly from the tube to the surface requiring protection, making it practical for field service and shop work alike.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eActs as a heat sink barrier to protect rubber seals, plastic components, and adjacent surfaces from brazing heat\u003c\/li\u003e\n  \u003cli\u003eColor-change indicator shifts from dark blue to light blue as the paste absorbs heat, providing a visible thermal warning\u003c\/li\u003e\n  \u003cli\u003eNon-toxic, asbestos-free, odorless, and harmless to skin  -  safe for regular field use\u003c\/li\u003e\n  \u003cli\u003eApplies directly from the tube with no mixing or preparation required\u003c\/li\u003e\n  \u003cli\u003eCleans up with a dry cloth or water rinse and leaves no stains\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eSuitable for use on ball valves, solenoid valves, and reversing valves during brazing and soldering operations where adjoining rubber or plastic seals require heat protection.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eApplied by HVAC technicians, refrigeration mechanics, and plumbers before torch work begins. Apply a sufficient layer of paste to all heat-sensitive surfaces adjacent to the joint being brazed or soldered. Monitor the color-change indicator during the operation as a guide to heat absorption. Wipe off or rinse with water after work is complete before returning the system to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.68 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 2.99 inches x 2.01 inches x 8.74 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor Indicator\u003c\/strong\u003e: Dark blue to light blue (heat activated)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToxicity\u003c\/strong\u003e: Non-toxic, asbestos-free\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCleanup\u003c\/strong\u003e: Cloth wipe or water rinse, no staining\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: UNIWELD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 91861\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"UNIWELD","offers":[{"title":"Default Title","offer_id":51998038262066,"sku":"91861","price":25.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/517bb17aae02926b158db9559683d545.jpg?v=1789994545","url":"https:\/\/voomisupply.com\/products\/uniweld-91861-cool-blue-heat-sink-paste","provider":"Voomi Supply","version":"1.0","type":"link"}
