Abstract
A centralizing washer for use in, for example, a plumbing installation in which a pipe is mounted in or connected to an article of sanitaryware creating a gap between the hole in the sanitaryware and the pipe. Projections extend axially from the washer for locating in the gap so as to centralize the washer substantially with respect to the hole in the sanitaryware. Optionally, the washer is splittable, comprising separable parts which are held together by hinge or completely separable. When the washer is in the open configuration, it may be fitted to or removed from the pipe without having to remove the pipe securing nut. To close the washer, the parts are urged together until a key projection locates in a socket. In the closed configuration, the washer substantially encloses the pipe.
