ARO L26121-100 Lubricator

ARO L26121-100 Lubricator is a compact inline oil feeder from Ingersoll Rand’s ARO Mini Series designed to deliver a controlled amount of lubrication into the downstream air line for small pneumatic tools and automation components. It uses a 1/4" NPT port, with a polycarbonate bowl and guard that holds about 1.0 oz (approximately 33 ml) of lubricating oil, and a transparent sight dome that provides 360° visibility of the oil level. The glass-reinforced body includes a top-mounted oil adjustment needle and a tamper-resistant plug for precise, repeatable drip-rate control, and it supports up to 200 psi inlet pressure. This model is intended to be installed close to downstream components to ensure consistent lubrication, and it is listed in distributors' catalogs as part of the 1000/Mini Series; some listings note that L26121-100 is discontinued by the manufacturer.
