Abstract

A joint for connecting piping to a threaded attachment forming e.g. an appliance outlet comprises an annular sealing body 9 which can be locked by means of a ring nut 3; the sealing body 9 has an external portion 14 made of elastomeric material and an internal metal core 10 closely joined together; the external portion extends at one end 16 beyond a flared end 12 of the inner core and exhibits tapered surfaces 6 and 13. At the opposite end 11 the inner core exhibits an internal diameter smaller than that of the pipe 1 and the external portion exhibits in that zone a thicker section 15, capable of resting inside the end edge 8 of the threaded attachment 2. Annular protuberances may assist the seal between body 9 and pipe 1. Sealing is effected by tightening ring nut 3 causing radial deformation of portion 16 against a pipe 1 and axial compression of portion 15 against edge 8 of attachment 2; the integral metal core enables greater speed of installation whilst preventing rotation of portion 16 during tightening. <IMAGE>
