Review on 🔄 R410A Adapter: 5/16 inch SAE Female to 1/4 inch SAE Male Flare for Air Conditioners - HVAC Set: 2 Straight + 2 Angled Adapters by Chris Quinto

I bought them for a mini split system I installed at home. I was looking for an adapter that would push the valve properly. I've searched and found that many people have had issues with a valve not squeezing too hard or not enough. I will add photos to my review soon, but for now I will explain everything. They have an adjustable valve pressure inside, like the valve stem of a tire. You can use a valve stem puller to adjust it to increase the opening degree of the valve inside. Be careful not to press too hard, as the refrigerant will splash more when separating.
