SAE ARP6179 - Lubricant Compatibility with O-Rings

We perform testing by SAE ARP6179 to evaluate the compatibility of elastomer O-rings used in gas turbine engines with lubricants and reference fluids. This test method provides procedures for exposing specimens of elastomer materials (AS 568-214 size O-rings) representative of those used in gas turbine engines to lubricants or reference fluids under defined time and temperature conditions. This test includes both suspended and compressed O-rings. Resultant changes in the O-ring's physical properties (tensile strength, elongation, hardness, mass, volume, and compression set) are measured to determine the amount of deterioration of the elastomer.

We also perform elastomer compatibility testing by Def Stan 05-50 (Part 61) Method 22FTM 3432FTM 3433FTM 3603FTM 3604, and MIL-H-22072 §4.6.9. These different test methods use different instruments or procedures or are used for certain sample types.
