A pass-through dual containment fitting that protectively seals a portion of pass-through tubing has a fitting body that incorporates a first end, a second end and a collar, each having a longitudinal bore for receiving the pass-through tubing. The second end having an extending nose portion. A radially compressive sealing device is engagable with the first end of the fitting body. When the radially compressive sealing device is fully engaged with the first end a fluid-tight seal is formed between the device and the fitting body. A dual containment sealing device incorporates containment tubing having a flared end and a flared end fitting. The extending nose portion of the fitting body is inserted into the flared end. The flared end fitting engages the second end of the fitting body to compress the flared end to the extending nose portion to form a fluid-tight seal between the dual containment sealing device and the fitting body.

A semi-conductor chip tray and associated retainer and method of use. The tray is provided with a plurality of side notches and tabs which are configured to admit and engage a plurality of posts and flanges, respectively, which extend from the retainer. The tray and retainer are attached to each other by setting the retainer on top of the tray in a linearly offset manner wherein the posts of the retainer extend into the corresponding side notches of the tray. The retainer is then aligned with the tray in a relative sliding motion. During alignment, the flanges of the retainer engage the tabs of the tray to secure the retainer to the tray. The tabs of the tray are provided with recesses which are configured to snugly receive projections which extend from the flanges of the retainer, thus allowing the retainer to be locked in a predetermined position as the retainer and lid are aligned. This locking feature facilitates alignment and prevents inadvertent or accidental displacement between the retainer and the tray.

A pair of semcircular jaws seal against the outer periphery of a pipe adjacent a butt weld joint in the pipe. The jaws have annular pressure rims that apply mechanical pressure against the outer surface of the pipe; and the jaws provide an annular manifold cavity between the pressure rims through which high gas pressure is applied against the joint and adjacent areas of the pipe, all for the purpose of slightly deforming the pipe and opening up any fissure that may exist by reason of an imperfect joint. In a modified form, a cylindrical shroud carries an annulus of balls for supporting against and applying deforming pressure on side portions of the pipe as the shroud is rotated around the pipe.
