Abstract:
A test plug for in-situ testing a glove installed in a glovebox, comprising:a. a top plate having an interior surface that defines a circumferential groove; b. a pressure gauge connected to said top plate for monitoring pressure within said glove; c. an inlet valve connected to said top plate for introducing a pressurized gas within said glove; d. a base plate spaced apart from said top plate a variable distance; e. a diametrically expandable sealing mechanism fitting within said circumferential groove of said top plate and having a sealing exterior surface, said sealing mechanism engaging said base plate to diametrically expand said exterior surface when said variable distance between said top plate and said bottom plate is reduced; f. a plug coupling mechanism engaging said top plate and said bottom plate to vary said variable distance; g. a first particulate filter attached between said glove interior and said pressure gauge to reduce the possibility of contamination of said pressure gauge; and h. a second particulate filter attached between said glove interior and said inlet valve to prevent: i. releasing any possible contamination out of said pressurized glove, or ii. introducing any outside contaminates into said glove.
