  • Patent number: 6874824
    Abstract: 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.

  • Patent number: 5735307
    Abstract: A combination of parts including a single piece valve body for a valve which is interchangeable between a straight valve and an angle valve. Each of the three bores of the valve body is adapted to operatively receive the valve opening and closing mechanism, the other two bores receiving fittings for attaching the flow conduits. One of the bores is perpendicular to the other two bores. If the opening and closing mechanism is received in this bore, the assembly comprises a straight valve. If the opening and closing mechanism is received in one of the other bores, the assembly comprises an angle valve. The three faces of the valve body through which the bores extend are machined substantially identically and symmetrically to the center thereof which is the point of intersection of the axes of the bores so that each bore is able to accommodate interchangeably the valve opening and closing mechanism and the fittings.
