BSO-18 is a silicone fill fluid designed as a fluid for diffusion pumps  for applications where high vacuum in combination with elevated temperatures are present. In cold outdoor applications its relative high viscosity might result in longer response times. Under those conditions, heat tracing and/or insulation of capillaries is recommended or a temperature compensator can be applied. Typically used for applications with high vacuum in combination with high temperatures
