SEAL WITH UV DYE  combines our fastest-acting, polymer-free refrigerant leak sealer with the brightest UV dye on the market. It’s engineered for HVACR systems to quickly seal small to micro-sized refrigerant leaks while simultaneously tagging leak points with high-visibility dye for precise, traceable diagnostics. If a leak is too large to seal, the dye makes it easy to locate and repair the exact source—reducing callbacks, saving refrigerant, and speeding up service.
