Yellow Jacket R410A Flaring Tool
Split A/C units use a flaring method to join the refrigerant tubes that connect the indoor and outdoor units. More specifically, flares are required on each end of the line set to connect the evaporator and condenser.
As an HVAC contractor, time is money—and when you get the job done right the first time, you can save yourself both.
When there is a callback for leaks, it is often incorrect flares that are to blame and not broken equipment. And when that happens, you are at fault. You have to go back out to your customer’s property and re-flare the piping to create a strong enough seal to hold in the R-410A. This will take at least 1 – 2 hours, plus travel time, to diagnose and recharge the HVAC system. This free-to-the-customer callback just cost you billable time that you could have been using for a paying customer.
Since R410A is a much higher pressure than older refrigerants, mini split manufacturers often require a larger diameter, deeper flare to produce stronger joints. While the angle of an R410A flare is the same as a Standard flare, it needs more surface for more area to seal against the flare fitting. This higher collar flare will work in all systems, not just R410A.
The size of the flare is determined by how much tubing is pushed through the flare block, so if you’re using a tool like the YELLOW JACKET Eccentric Cone Flaring Tool, be sure to check the manufacturer’s height requirements for R410a
