Product Review

TSI Supercool 43460 hand turn Dye/oil injector is specifically designed to service HFO-1234yf A/C systems. The quick-connect style allows professionals to easily service HFO-1234yf systems. It's especially great for introducing from 1/4 oz. up to 2 oz. of U/V Dye, lubricant and leak Stop to a closed A/C system without adding refrigerant. Unlike other similar tools, ours does not require a manifold gauge to use on low side of pressurized systems. Designed for real-world operating conditions, TSI Supercool provides an unsurpassed level of service, performance, protection, and fluid life.
