ABSTRACT:
A tube protector device includes a first cap member, the first cap member being configured to fit over and substantially seal a first end of a tube; a second cap member, the second cap member being configured to fit over and substantially seal a second end of the tube; and a fastening device adapted to resiliently bias the first cap member toward the second cap member. At least the first cap member includes a collar configured to surround a portion of an outer surface of the tube and an angled tube support member configured to fit within the internal diameter of the tube, the collar and the angled support being configured to receive the first end of the tube therebetween. The first cap member further includes a sealing member, a particle barrier and/or a shock absorber between the collar and the angled support member. The tube protector may be used to protect, for example, quartz vacuum tubes from being contaminated by particulate matter, as well as from scratches and chips that may form in its surface during insertion and withdrawal from e.g., semiconductor manufacturing equipment, such as diffusion furnaces.
