Rubber Seal-Important Factors In O-Ring Design And Applications

O-ring design isRubber Seal one of the most important elements in the development of sealing applications。 These solid rubber seals block the passage of liquids and gases when they are compressed between two surfaces。 Among the major considerations are the o ring gasket material and size of the rubber o rings。

A wide range of applications

These seals are versatile and can used in applications ranging from garden hose couplings to refinery and aerospace。 They offer O-ring design engineers and plant operators numerous benefits。 Apart from being used inRubber O-Ring static and dynamic applications， they occupy little space and have the ability to form efficient seals inRubber Parts both directions。 They are also compatible with a range of fluid media and can resist temperatures ranging between €"65C and +315C， depending on the material they are made from。 Seals made from PTFE can function at temperatures as low as €"200C。 Design engineers today have an array of rubber o rings and o ring gasket sizes in addition to comprehensive information for buyers， designers， and maintenance staff。 There is also a selection of Oring Warehouse kits also available online。

Internal and cross sectional diameters

When it comesCustom Mold Rubber Parts to o ring gasket sizes it is important to note that the size is defined by the ID or inside diameter and CD or cross-sectional diameter。 Those with smaller cross-sectional diameters are more resistant to explosive decompression and possess better physical properties。 Seals with a larger cross sectional diameter are more resistant to rolling within a groove while can be used in dynamic applications。 Any error in the selection of an O ring Gasket could result in leaks and damage to the application。

Dimensional tolerances

One of the major considerations in O-ring design is dimensional tolerances。 TheRubber Gasket AS568B is a combination of Class I and II tolerances。 Class II was for Orings manufactured from high shrinkage elastomers such as fluorocarbon and fluorosilicone with higher tolerances。 Class I was for designs made from other elastomers。 Seals made with Class II tolerances are as effective as Class I tolerances since larger diameter o-ring designs have slightly wider dimensional tolerances which does not affect o-ring volume significantly。 Therefore， AS568A uses a single set of tolerances for inside diameters of less than。5 inch， which is the former Class I tolerances。 Class II tolerances are used for larger O-ring design。

Purchase the right seals

Rubber o rings and other specialty o-ring suppliers can be found online。 They offer a wide range of seals made from elastomers that will allow you to get more return on your investment with less time and effort。 Manufacturers provide Oring Warehouse and other designs in various sizes to meet the needs of businesses。 These seals are designed and engineered to precision。 The material used is carefully selected to suit a variety of applications and operating conditions such as temperature and pressure。 Thermoplastics and synthetic rubbers are most common。 Prior to making prior to purchasing an O ring Gasket， make sure to consider all the factors including temperature， chemical resistance， friction， pressure， and durometer - the measurement of hardness of the elastomer。
