The Shore durometer scale measures material hardness. In other words, it measures how resistant a material is to indentation. It’s one of the most important specs to understand when choosing rubber components like o-rings or gaskets. The scale helps engineers compare soft and hard materials across a variety of applications. Shore hardness is measured by […]
O-rings are one of the smallest parts in an air conditioning system, but they are also one of the most important. A failed o-ring can lead to refrigerant leaks, compressor damage, and costly repairs. There are some key factors that will ensure that AC o-rings work well in applications like HVAC or refrigeration. These include […]
In many systems, o-ring failure is a lubrication issue. O-ring lubrication is central to seal performance, especially during installation and in dynamic systems. A compatible lubricant can prevent damage, reduce friction, and improve long-term sealing integrity. However, not all lubricants work with every elastomer. Choosing the wrong one can shorten seal life or lead to […]
Accurate o-ring sizing is essential for seal performance, longevity, and system reliability. Undersized or oversized o-rings can leak, wear out early, or fail under pressure. Knowing how to measure an o-ring accurately helps ensure better sealing, longer life, and fewer headaches. To properly size an o-ring, you need three critical measurements: inside diameter (ID), cross […]
