A pipe fitting, especially a pipe junction, is formed of resilient plastics material and has sockets integrally joined by tubular necks to a hollow body, which is stiffened by longitudinal ribs extending between collars adjacent the necks and circumferential ribs connecting the longitudinal ribs, so that the load-bearing capacity is comparable with that of pipes, especially clayware pipes, which it is used to connect, without use of excessive plastics material, and yet affording allowance for the usual departures of pipe-ends from true circularity and tolerances on nominal diameter, as well as accommodating axial and/or angular misalignment over and above any between the pipes allowed for in the design of the fitting. |
