A tribometer includes a main chamber to conduct testing under controlled environmental conditions, such as different chamber pressures and different temperatures. A shaft extends through the main chamber to initiate component movement inside the main chamber. A secondary fluid seal chamber is formed in a wall of the main chamber around each shaft. A first seal is formed around the shaft on a first side of the secondary chamber. A second seal is formed around the shaft on a second side of the secondary chamber.
