Abstract
An apparatus is provided for an access port through an insulative coating or vapor barrier wrap on tubing in cold chemical processes. The apparatus seals against entry of vapors and moisture into the access port which might accumulate there and freeze, causing ice build-up and preventing access of testing probes to the tubing. The apparatus also has an insulative effect against transfer of external ambient heat through its structure to the tubing.
