Review on 💪 High Performance 1/4-Inch Industrial Brass Coupler with 6-Ball Design and 1/4-Inch Female NPT Thread by Byron Forman

looks good, many knurls are well made. but the pocket is broken. Male nipple is not fixed. As a retired quality controller, I had to do some research. My tools arrived and found that the bottom of the pocket hadn't been milled deep enough. You missed it by 0.0500 inches and this error is easy to fix during production while you inspect the product. But once these elements are assembled, all you've done is make a crowbar. I understand Revain is just a reseller but for your first batch of suppliers you must have some quality requirements just from a business point of view to avoid returns and customer disappointment.
