Proseal XL4 with Dye Direct Inject for 1.5-5 Ton Systems, 8 Pack

ProSeal XL4 with Dye Inject is a revolutionary product that effectively finds and seals leaks in AC systems. Unlike other products on the market, it travels with the gas, making it faster and more efficient at locating leaks. When used according to the manufacturer's instructions, it can seal most leaks, including small holes in the A/C condenser, evaporator, fittings, and metal line sets. This not only saves energy, but also lowers refrigerant emissions.

In addition to sealing leaks, ProSeal XL4 with Dye Inject forms a hard seal on metal, Schrader valves, o’rings, gaskets, a/c condensers, evaporators, line sets, and solder joints. While it can form a seal on the Schrader valve, it will release when connected, allowing you to use the Schrader if necessary. If there is still Proseal XL4 with Dye in the system, it will reseal the Schrader. The product uses a highly visible fluorescent-yellow dye that is the same as the one used by auto makers in car A/Cs.

ProSeal XL4 with Dye Inject is compatible with all refrigerants except ammonia and is designed for one-time use. It is a concentrated formula that does not require pumping down R410 or other units, and does not need an injection-hose or caulk-gun for application. The concentrated formula means less material in the system, making it more efficient and effective.

This product is best suited for use in heat pumps, split and mini-split units, packaged units, microchannel coils, coolers, and commercial units. However, it should not be used in ammonia systems. With its innovative technology and easy application, ProSeal XL4 with Dye Inject is a reliable solution for finding and sealing leaks in AC systems.
