ABSTRACT:
An inner sealing portion seals a tubular port, which is provided to a receiver that receives water, at a first location of the tubular port. An outer sealing portion seals the tubular port at a second location of the tubular port spaced from the first location on an outer side of the inner sealing portion. A sealed space is formed between the inner sealing portion and the outer sealing portion. A tracer gas for performing a leak test of the outer sealing portion is enclosed in the sealed space. An amount of outwardly leaked tracer gas, which leaks from the sealed space through the outer sealing portion, is measured with a leak test device.
