Review on 🔧 Trico FA 1007 Central Lubrication Straight: Enhance Equipment Performance with Precision Lubrication by Ananta Crowley

Thread is accurate but center hole is very small. I'm not sure why the hall was made so small as the outside diameter was four times larger. I ended up drilling the hole to a larger size. I used it to convert a Blackstone grill into a hose for my RV. My photo shows a fitting with a larger hole I drilled.
