Guards ## Figure 1 Diagram of seal Two all-metal demountable cryogenic seals with an outside diameter of 36.6 ram, inside diameter of 27.2 mm and thickness of 0.51 mm were leak tested at room temperature (300 K), liquid nitrogen temperature (21 cycles at 77 K), liquid helium temperature (nine cyc
Interfaces between metals and polytetrafluoroethylene (TFE) are common in cryogenic systems. In this paper we present results from measurements of the temperature dependence of the dynamic coefficient of friction between commercially pure copper and TFE. The effect of the copper surface finish was a
