Hardness
Resistance of rubber to forced distortion as measured by the indentor point of a durometer gauge.
Hardness, Shore A
Durometer reading in degrees of rubber hardness as measured on a Shore A gauge. Scale is 0-100, with higher numbers indicating greater hardness.
Hermetic Seal
An airtight seal.
