PURPOSE:To prevent leakage of fluid by pressure contacting and securing first and second pipes having tapered face while butting to the pressure insertion hole of housing. CONSTITUTION:First iron pipe 9 formed with tapered face 9a at the tip is pressure inserted through one open end 1b of pressure insertion hole 1a formed through the housing 1. While second iron pipe 10 is pressure inserted through the other open end 1c then both of said pipes 9, 10 are butted on the tapered face 9a to be secured while pressure contacting. The face pressure P functioning at the tip of said pipes 9, 10 is decomposed into radial component K and axial component F through pressure insertion thereby respectively pipe will deform in accordance to the profile of counterpart pipe and contact tightly thus to ensure sealing performance. |
