Lubrication Oilers

Trico Constant Level Oilers are a trusted solution for maintaining consistent oil levels in bearings, gearboxes, pumps, and other rotating equipment. As the UK’s official distributor for Trico lubrication products, Able Instruments offers comprehensive support across their full oiler portfolio, including the globally recognised Opto-Matic and Closed System models, as well as the more recent Watchdog and Sensei IIoT-enabled oilers.

This category covers the full range of Trico’s gravity-fed lubrication systems, which are designed to automatically maintain the correct oil level inside machinery, regardless of changing ambient conditions or equipment activity. These oilers help prevent costly equipment failure by ensuring that oil levels do not fall below the manufacturer’s recommended threshold, a key factor in asset reliability and bearing life.

Whether you’re operating in clean environments or in conditions prone to contamination and dust ingress, Trico’s product range includes both open and closed system oilers, in a variety of capacities, configurations, and materials. From simple glass reservoir oilers to sealed units with adjustable levels and integrated sight gauges, there’s a solution tailored to every application.
