A thread on an oil filter, or any other machine part, is often denoted by a measurement followed by a numerical value and the letters UNF or UNC. But what exactly do UNF and UNC signify? These are not just random acronyms; they represent the two principal thread types under the Unified Screw Thread (UST) Standard.

An oil filter element used with a compressed air system will usually have a threaded connection. Sometimes the oil filter will have two threaded connections. When it comes to selecting an oil filter for your compressed air system, understanding the threading is essential to ensuring compatibility and optimal performance. This becomes even more important when shopping on a website, where you can't check to see if the oil filter thread fits your equipment.
