摘要： A double containment fitting for connection to a double containment tubing system with an outer, secondary containment tubing surrounding an inner, primary tubing. The fitting includes a fitting body defining a central passageway, the fitting body having a center portion disposed between opposed first and second body ports. The fitting body is configured to receive the tubing system into the first body port. The central passageway has a diameter in the first port selected to allow the secondary tubing into the first body port. A connection system mechanically secures the secondary tubing to the first body port.

摘要： A torque limiting wrench for tightening nuts on a fitting, and a jaw structure for the wrench. An exemplary embodiment of the wrench includes a handle structure, the jaw structure pivotably mounted to the handle for movement between a tightening position and a fully tightened position. A mechanism applies a force to hold the jaw structure in the tightening position, and allows the jaw to pivot to the fully tightened position when a pre-set torque limit is exceed. The jaw structure including a plurality of spaced teeth supported on a curved jaw arm and having a circumferential extent of less than one half the entire circumference of the nut to be tightened, so that the jaw structure can be engaged to the nut without requiring an axial movement from a first end of the nut toward a second end of the nut.

摘要： A method and apparatus for assembling a high purity liquid distribution system is described. A distal end portion of the tube is heated then pushed over a sleeve so that the distal end portion can have a shrink seal fit over the sleeve to mitigate accidental or inadvertent pull out of the tube from a fitting. Other benefits are also achieved such as minimal flow restriction of the liquid flowing through the joint and the tube.
