ABSTRACT:
A gripping saddle and O-ring apparatus comprising a hub structure having a central aperture therethrough, resilient flanges extending from each end of said hub structure and integral therewith, and thus providing a central groove therebetween for reception of a resilient O-ring therewith. Depending upon the size of the O-ring, the flanges will be only slightly deformed outwardly or greatly deformed outwardly. When this structure is used with laboratory apparatus containing corrosive liquids, the embodiment with slightly expanded flanges is preferred, while when the apparatus is used for stop cock securing functions, the greatly deformed flange apparatus is preferred.
Preferably, the saddle hub structure is made of Teflon or other fairly slippery and non-frictional plastic material, while any type of rubber or rubber composition may be employed for the O-ring. By separating the O-ring from any direct contact with corrosive liquids, the rubber or rubber-like material which is normally non-resistant to such corrosive liquids is fully protected therefrom. However, the resiliency and inherent retention bias force with such a rubber O-ring is important in combination with the plastic of the saddle hub which has a tendency to creep or flow as time passes.
An embodiment uses two or more O-rings, and hub structure having double (or more) pairs of resilient flanges. A further modification includes a plurality of grooves, or threads internally of the hub structure.
