Abstract: An improved seal arrangement in an assembly such as a valve assembly in which a compression member is provided to press a seal between the compression member and the valve body. In a preferred form, the compression member includes a recess which receives a first portion of the seal, and a second portion of the seal is disposed between the compression member and the valve body. In addition, a first inclined surface is provided in the recess of the compression member. The first inclined surface contacts a second inclined surface provided on the first portion of the seal. A third inclined surface on the compression member contacts a fourth inclined surface provided at a juncture between the first and second portions of the seal. Further, a fifth inclined surface is provided on the housing to contact a sixth inclined surface provided on the second portion of the seal. The arrangement creates lateral or side loads between the seal and the valve stem and also between the seal and the valve body to prevent or minimize leakage over a large number of valve operating cycles.
