- The seal efficiency and environmental resistance of various elastomeric o-rings and a metallic joint that were immersed in geothermal brine or water at elevated temperatures and pressures were determined. A leakproof seal was maintained with a stainless steel Conoseal-joint for 100 hours in water and 24 hours in geothermal brine at 275/sup 0/C and 34.5 MPa (5000 psi). Only very small quantities of moisture penetrated o-ring seals made from Kalrez, a perfluoroelastomer, ethylene/propylene rubber and a Parylene C coated Viton o-ring. All other rubber seals failed catastrophically.
