Our custom Spike pressure gauge is designed to be the toughest out there. The original pressure gauge we sold was not fluid filled and was susceptible to damage. When dropped or even during shipping the needle could slip a gear resulting in an incorrect pressure reading. Our new pressure gauge is a commercial quality gauge that's filled with food grade glycerin. The glycerin fluid helps absorb any impacts and prevents the needle from reading incorrectly.
