A seal and seat for ball valves is a circular, elastomeric open torus which is fitted between the ball element and the housing. The open torus has within it, a substantially 'v' shaped spring that is fitted within the 'u' shaped opening of the torus. In normal operation, the spring member is slightly compressed between the ball and the housing and the ball can 'float' between a pair of substantially similar seals on the input and output sides of the ball valve, respectively.

An access port cover is fitted with a sealing plug that is adapted to fit inside a conduit to provide an occluding seal. The conduit is also fitted with an inner flap that is automatically closed and latched when the cover is closed and latched. In a preferred embodiment, a ridge in the inner wall of the conduit cooperates with a support plate to compress the plug between the cover and the plate, extruding the plug radially into sealing engagement with the inner wall of the conduit.
