ABSTRACT:
A portable sample cylinder assembly is provided for transporting a fluid. The sample cylinder assembly includes a housing defining in part an internal fluid chamber, a first end cap at one end of the housing, and a second end cap at an opposing end of the housing. At least one of the end caps includes a stop surface and an annular groove. An elastomeric seal is positioned within the groove for static sealing between the end cap and the housing. The end of the housing includes an end surface for metal-to-metal engagement with the stop surface, and a compressional surface for applying a compressional force to the elastomeric seal in response to axial movement of the end surface toward the stop surface. A plurality of connector rods may be used to controllably move the end cap axially toward the housing and thereby compress the elastomeric seal to reduce the permeability of the seal. The elastomeric seal preferably has a circular cross-sectional configuration prior to compressional force being applied to the seal, and a base portion of the groove opposite the compressional surface with respect to the elastomeric seal as a semi-circular cross-sectional configuration.
