Oil wiper rings prevent oil migration past the wiper gland into the pressure packing area and cylinder. Leakage can cause serious problems such as gas contamination and may lead to premature failure of critical compressor wear parts. It is designed to effectively provide positive containment of lubricants within the crankcase. It is constructed of many different variety materials including cast Iron, bronze, babitt and carbon filled teflon.

Oil-air ratio regulator is designed to provide the correct fuel/air ratio for oil-fired burners. It is used to proportion fuel flows to modulating oil burners. Combustion airflows produce a proportional pressure signal that is applied to the regulator to set the outlet oil pressure. On initial adjustment the desired oil flow rate is set to match the burner air capacities. The regulator holds this oil to air ratio at all firing rates. It has a unique balanced valve design for inlet oil pressure in the 40 psig to 100 psig range. A constant oil pressure is required at the OAR inlet.

The oil-based inhibitors include water-displacing and non-staining rust preventatives that provide humidity and salt spray protection. It is used after machining or alkaline cleaning operations, and some may be used over black oxide, zinc phosphate or bare ferrous alloys. The water displacing and non-staining rust preventative displaces water after machining or alkaline cleaning operations.
