How does an O Ring work?

What is an O Ring and how does it work? O Ring Basics The O Ring is one of the most standard and easiest types of seal for dynamic and static installations. The design of the O Ring’s groove is fairly straightforward. A dependable and economical seal is acquired by following well-developed principles for groove geometry. The primary reason an […]

What is a Gasket and how it works? What is a Gasket? A Gasket is an elastomeric component that covers the intersection between two surfaces. They are usually manufactured from a variety of materials, including rubber, cork or paper, metal, copper, and foam. This flexible element can be used for a broad scope of purposes due to its functionality. These […]
Read MoreTemperature range of Viton™

Viton™ (FKM/FPM) temperature range Fluoroelastomers are known for their excellent resistance to chemicals and temperatures. They have low compression set, resistance to ozone, very low gas permeability, are self-extinguishing and have remarkable ageing features. Viton™ has developed a significant eminence in the sealing industry due to its performance features. Fluoroelastomers are highly fluorinated carbon-based rubbers that are used in installations […]

What are Circlips, types of Circlips and what are they used for? What are Circlips? Circlips, Retaining Rings and Snap Rings are fasteners that grasp elements or installations onto a shaft or in a dwelling/bore when assembled in a groove. Once it’s fixed, the exposed piece functions as a shoulder which holds the particular element or installation. Circlips solve problems such […]

What is Rapid Gas Decompression (RGD)? What are the causes? How it affects elastomers? What is Rapid Gas Decompression (RGD)? or What is Explosive Decompression (ED)? Rapid Gas Decompression (RGD) is an occurrence that frequently appears whilst high-stress gas particles drift into the elastomer in the concentrated/compressed form. When the stress ambient to the elastomer is quickly relieved, the compressed gas […]
Read MoreWhy should you use Food-Grade Silicone?

Silicone compliant with Food Regulations, what are the features? There are plenty of options when it comes to sealing materials. However, in the food processing industry, it is very important that each element that interacts with the seal is left untouched. Furthermore, despite the fact that silicone is ‘practically’ non-toxic, only a particularly developed food grade silicone is suitable for […]
