SUPERLOK Tube Fittings tighten easily and are leak free under shock, vibration and temperature cycling. The use of SUPERLOK tube fittings result in additional productivity and cost reduction for the end user. The best interior surface finish in the industry reduces particle entrapment and improves the flow of fluids and gases. Review: Foolproof design worked great - The torque indicator design is awesome. I was installing this in an awkward location and it was getting very hard to keep tightening, but I kept going until the red plastic pieces popped off with a snap. Being my first time ever using stainless steel tubing and compression fittings, I had no feel for how tight to make them. This made it very easy and provided peace of mind that I did it right.
