Recommended as Required Our Ingersoll Rand 32015117 Equivalent Ring Kit contains all theparts necessary to replace the high pressure pistonrings on Ingersoll Rand CompressorModels 5T2NL. Worn piston rings are often a contributing factorin the decline in performance of a compressor that has been inservice for an extensive period of time. IngersollRand recommends replacing the piston rings when acompressor does not meet its normal air delivery or when its oilconsumption is considered to be excessive. Generally, anycompressor consuming more than 2 oz. of oil per 100horse-power-hours does not meet commercial standards and wouldrequire piston ring replacement. eIndustrialSolutions provides quality IngersollRand equivalent parts that meet or exceed the OEMspecifications. Aftermarket parts are more cost effective thanbrand name parts and can typically allow for a reduction in yourannual maintenance costs over the life of the compressor.
