ABSTRACT:
A holder for use with a refrigerant purity sampling tube is provided with a base and two end fittings. The end fittings are adapted to establish a releasably fluid tight relationship with the opposite ends of a sampling tube. One end fitting is fixed to the base and the other is slideably mounted for movement toward and away from the fixed fitting. A spring biases the movable end fitting toward a fixed fitting. Movement of the movable fitting against the biasing force allows removal and insertion of a sampling tube. When a new tube is inserted, the biasing force assures fluid tight engagement with the seal.
