Review on 💧 Dernord Barbed Adapter Sanitary Fitting for Hydraulic, Pneumatic, and Plumbing Applications by Eric Power

They are manufactured in Metric units not English as advertised. And yes, there is a difference. I ordered four notched 3/4" sanitary triple clamp adapters and received three 50.5mm adapters and a fourth adapter that is about 1/8" smaller in diameter than the other three. They are all slightly smaller than a true 3/4" barbed adapter. The supplier should update the description to reflect that these are indeed metric adapters. Also, they are made in China. Delivery was very fast, therefore I give two plus half stars.
