Abstract

PURPOSE: To obtain positive airtightness and enable the test for water leakage at joints of pipings with ease just through assembling the rigid base within the piping by an apparatus which comprises the cylindrical rigid base divided into a plurality of pieces and the elastic sealing member.
CONSTITUTION: A cylindrical rigid base RS is divided into a plurality of arcuate bent plate pieces 1 at its peripheral portion. These pieces are connected each other by L-shaped members 2 to form the integral rigid base. On the periphery of the rigid base there is mounted an elastic sealing member ES made of rubber-like elastic materials and comprising a cylindrical flexible coating portion 3, elastic bases 4 and fin-like peripheral wings 5 at both ends. Thus, by assembling the rigid base Rs and the elastic sealing member ES within the pipping PP consisted of a socket pipe 9 and an inserting pipe 10 connected by a packing member 11 and then forcedly introducing pressure fluid from an inlet pipe 6 there-into, the fin-like peripheral wings 5 are self-sealed by the internal pressure so that leak of water for the packing member 11 or others is detected with ease.
