O-Ring Durometer vs Pressure and Clearance Gap Groove Design Reference. High Pressure/Extrusion. Most elastomeric seals are designed to operate within ambient pressure to about 1,500 psi. At very high pressures, the seal must have sufficient strength to resist extrusion into the clearance gap.

An o-ring's durometer is the measurement of that specific material's hardness. This scale is also measured by an instrument called a durometer gauge, which uses a spring-loaded rod to indent the material and provide a reading. The durometer scale runs numerically from 0-100, with lower numbers indicating softer materials and higher numbers ...

Low Durometer O-Ring . The simple solution to lowering the compressive load of an O-ring is to switch to a softer O-ring material. Changing to a softer durometer material can result in up to 50% reduction in the force needed to compress an O-ring. For example, with a .070" cross sectional thickness, a 90 durometer O-ring compressed 20% needs ...

Durometer is a number used to identify the hardness of a rubber or plastic material. The measurement, in Shore A or D scale, tells us how stiff and resistant you want your part to be. For example, a rubber extrusion on the low end would be soft and able to bend. On the high end, the extrusion would be stiff and resistant to movement.

This popular o-ring material family comparison shows basic rubber material family properties and performance plastic properties. The guide includes generalized recommended o-ring mateiral uses and non-recommended uses with typical material mechanical properties. Specific material compound formulations can significantly alter the general ...

FFKM o-rings are utilized in the most demanding applications with dozens of compounds ...

Harder materials, like 70, 75 or 90 durometer compounds, offer greater resistance to extrusion. In dynamic applications, the hardness of the O-Ring is doubly important because it also affects both breakout and running …

Generally, most rubber materials fall under the rubber durometer scale of Shore A. Thus, if you need a rubber or O-ring durometer that feels like a running shoe sole, review our rubber hardness chart below, then pick Shore 70A. A rubber durometer of Shore 70A is the most commonly chosen material hardness for all applications. a. Shore 20A ...

Ring sizes in the U.S. range from 3 to 13.5 in adult sizes. Most women's fingers fall between 3 and 9, while men are typically between 8 to 14. These sizes are actually determined by millimeters. One millimeter is equivalent to .039 inches. But the fact is, most people have no idea what their ring size is.
