Abstract
A check valve comprises a body of elastomeric material having a tubular inlet at a first end with a radial flange. The body has a side surround with three equi-spaced valleys tapering together towards a second end opposite to the first end and having thereat sealing edges in the form of a triskelion. An openable mouth is extendible between said sealing edges of substantially the same areal dimensions as the tubular inlet.
