Review on 🔵 Upgr8 Universal Silicone Vacuum Hose Line - High Performance, 5 Feet Length, 2mm Inner Diameter (1/12 Inch), Blue by Kevin Nelson

Pros: This is a tube Cons: Poor tolerances Description: The tube is black as described and comes in a sealed bag. Brittle but acceptable for low vacuum service. I wanted to check it on a 3/8 coupling and it was very loose so I took out a caliper to measure the hose diameter and found it was about .409" inside. You can see in the picture where I adjusted the caliper to .375" to show the 3/8 pipe how much play there is. Now you can say "Is this normal for a 10mm tube?" but the answer is also no because the size is so big it's already 10.4+mm. Too big if the tolerances were better this would be an acceptable hose.
