A kit of parts for configuring and assembling a shut-off valve in the field has a valve body, a plurality of connection fittings, and a plurality of gaskets. The connection fittings each have a first end with a common configuration adapted to fit into any of three ports provided in the valve body. The connection fittings have second ends with different configurations adapted to connect with any of a variety of conduit configurations which may be encountered in the field.

Field configurable shut-off valve

A connection structure providing a sealed joint between first and second fluid conducting parts has a first seal surface on a first part, a second seal surface on a second part, and an annular elastomeric gasket positioned between the first and second seal surfaces. At least one of the first and second seal surfaces has at least one projection extending from a respective seal surface. The projection is adapted to pierce the elastomeric gasket and abut the opposing seal surfaces upon assembly of the first and second parts at relatively low, hand-tool torque levels.
