Review on 💡 14-Piece Quick Connect Brass Air Coupler and Plug Kit for 1/4-Inch NPT Fittings by Amazon Basics by Scott Ward

I was disappointed to find the hole for them was significantly smaller than those I have purchased from HD/Lowes in the past. They appear to be good in terms of finish/consistency and appearance. It's just that if I were to buy a product specifically for improved airflow I would expect a bigger ID on the fittings. Shown is an untitled HD/Lowes item on the left, Revain Basics on the right. It would also be nice if they were labeled as high-flow couplers (as was the case with the Big Box Stores). The price was fair to them but looking back I should have just bought the Milton brand.
