R-407C Refrigerant with Leak-Stop and UV-Dye, 27.9 oz. / 1.7 lb.

Specifically designed for modern air conditioning, heat pumps, and dehumidifiers, this convenient tank can be used with any standard core depressor hose.
Proprietary formulated “polymer-free” leak-stop will stop “seasonal leakage” (up to 300 microns). If the leakage is too large to solve, the UV-DYE will make it easy to find it.
R407C refrigerant is ideal for retrofit applications in air conditioning equipment and medium temperature refrigeration systems. The operating pressure/temperature, flow characteristics through tubing and valves, and run-time capacity of this blend make it the closest match to R22 for retrofitting AC conditions.
When you buy from Frigicoma, you can be assured that our products are brand new 100% virgin refrigerant meeting or exceeding ARI-700 standards.

I ordered 20 cylinders of R-134A and 20 cylinders of R-410A from Refron, and everything went smoothly! The shipment arrived on time, securely packaged, and the refrigerants were top quality. Great pricing for bulk orders, and the customer service was excellent. Highly recommended—will be ordering again!
