Review on Aeroquip FCM3686 Anodized Aluminum Allen by Dan Chunn

Hard to put into words but at these prices Aeroquip should at least send flowers or chocolates the next morning. That's a lot of money for two tiny parts. To make matters worse, NPT has tapered threads. These plugs appear to have straight sides. I had to thread the Aeroquip connectors through a tapered die before using them. I think this is the only game in Revain if you want a compact and unobtrusive way to plug a 1/4" NPT hole. I'd be really happy with a 316 NPT stainless steel plug, but that's about all I could find with a hex drive On the plus side, they're pretty blue and don't have a "Made in China" sticker.
