Abstract: A gasket comprising a first discrete component and a second discrete component, wherein the first and second components extend along the length of the gasket. The second component is arranged ranged relative to the first component so as to separate the first component at least from one of the two sealing surfaces. The first component is relatively hard in at least the thickness direction of the gasket and preferably incompressible and the second component is relatively soft in at least the thickness direction of the gasket and compressible.

Abstract: A retainer for a gasket used to connect modular piping in a modular gas delivery system to the gas flow controlling components protects the sealing surface of the gasket from scratches before assembly by suspending the gasket at least 0.003 inches inside the retainer, regardless of orientation. Additionally, a slit in the circumference of the retainer allows the retainer to flex open for insertion of the seal gasket, and to compress to a smaller circumference, for a tight fit inside the sealing counterbore. A chamfer on the ID of the retainer aids the easier insertion of the seal into the retainer. In the ID of the retainer, a groove engages a protruding portion of the seal. The depth of this groove is such that with a complete compression of the retainer where the circumferential gap is completely closed, the protruding edge of the seal still has some clearance. This clearance acts as a stop to prevent the retainer from being overly compressed.
