-13- Shear Seal Assembly Abstract A shear seal assembly has an inner sleeve and an outer sleeve with an elastomeric material bonded therebetween. One sleeve has a circumferential groove formed in the exposed wall thereof in which groove an O-ring nests. The assembly is mounted between two telescoping members that have limited relative rotation. The sleeve without the groove is press fit on or in one member and the sleeve with the groove will be spaced from the other member so that the O-ring will extend from the groove into sealing contact with said other member. Clips or retainers are provided for seating the grooved sleeve to said other member whereby limited relative rotation or oscillation between the members takes place without rupturing the elastomeric material. The shear seal can be removed without destroying the shear seal structure so that it can be reused.
