Fluid pipe coupling |
摘要 |
A fluid pipe coupling comprises a plug and a socket, at least one of which includes a cylindrical body member having an end portion adapted to engage the other and a caulking end portion, and an adapter member having a connector end portion adapted to be connected with a pipe member and a caulking end portion. One of the caulking end portions has a cylindrical caulking portion, while the other has a cylindrical caulking receiving portion adapted to engage the caulking portion. The caulking receiving portion has a plurality of annular grooves and annular projections therebetween on the peripheral surface thereof. The caulking portion and the caulking receiving portion engage each other with a seal member interposed therebetween. These two portions are caulked so that the cylindrical body member and the adapter member are coupled integrally with each other.
