O'Keefe, "Nonasbestos Gasket Test Results and Recom mendations" ABSTRACT The candidate nonasbestos gaskets (Tables I and II) are compared with the current production Lydall "Duroid 3102", Klinger "Oilit," and Reinz "Thermolit K" gaskets, Acceptable gaskets, based on sealed tube compatibility criteria, are: Vi-cfcOiak if6 9 -- best - Boise #DL2-238 (nonsulfurized version) -- acceptable Armstrong IfN80 92 -- acceptable Lyda1.3UJ-GTRG^20 0..... -- least acceptable The others on the list are not acceptable. PURPOSE Determine the reactivity of various nonasbestos gasket materials (Tables I and II) selected for e v a l u a t i o n by Jim Cole and Keith Vrlend. RESULTS AND CONCLUSIONS The nonasbestos gaskets best suited for a refrigerant/o i 1 envi ronment (as determined by the sealed tube method) are those exhibiting less refrigerant degradation and less corrosion of the copper and steel coupons than current production gaskets.
