What does o-ring durometer mean?
O-Ring durometer is the hardness of the o-ring material. Durometer scales run numerically from 0-100, with lower numbers indicating softer materials and higher numbers for harder materials. Durometer is just shorthand for “Shore hardness”.
How do you test the hardness of rubber?
Hardness value is determined by the penetration of the Durometer indenter foot into the sample being tested. The resilience of rubbers and plastics means that the indentation reading may change over time, so the indentation time is sometimes reported alongside the hardness number.2019-11-26
What is seal hardness?
Rocket Seals uses the Shore A scale. Normally, durometer hardness is referred to in increments of five or ten, such as 50 durometer, 70 durometer, 75 durometer, etc. O-Rings are available in almost all durometers, with 70 or 90 durometer, the most common in most compounds.2015-10-20
What tensile strength means?
tensile strength, maximum load that a material can support without fracture when being stretched, divided by the original cross-sectional area of the material.
How do you find the Durometer of rubber?
Durometers measure hardness by the penetration of an indentor into the rubber sample. The calibrated reading is expressed in a number value. The hardness values are always expressed in terms of plus or minus (+/-) five points (example: 60+/-5 Durometer).
Is a higher tensile strength good?
Tensile strength is one of the most important and widely measured properties of materials used in structural applications. High tensile strength plastics can take the place of metal in many applications, reducing weight and cost without sacrificing performance.

What is O-ring hardness?
Normally, durometer hardness is referred to in increments of five or ten, such as 50 durometer, 70 durometer, 75 durometer, etc. O-Rings are available in almost all durometers, with 70 or 90 durometer, the most common in most compounds.2015-10-20

Which is harder 70 or 90 durometer?
The hardness of rubber compounds is measured by the Shore A durometer; the higher the durometer, the harder the compound. 70-durometer hardness should be used whenever possible as it offers the best combination of properties for most O-Rings applications.
What is the purpose of a tension test?
It is used to find out how strong a material is and also how much it can be stretched before it breaks. This test method is used to determine yield strength, ultimate tensile strength, ductility, strain hardening characteristics, Young’s modulus and Poisson’s ratio.
What is a tensile ring?
A tension ring is a type of finger ring that holds a gemstone in place by pressure rather than prongs, a bezel or other mounting. The metal setting is actually spring-loaded to exert pressure onto the gemstone, and tiny etchings or grooves in the metal create a shelf that supports the gemstone’s edges.
What does it mean when tensile strength is high?
The tensile strength of a material is the maximum stress that can be applied to it before it breaks. The tensile strength of aluminum alloys can be increased by special treatments. Because of their high tensile strength, these products are suitable for boring in drilling machines.
How do you measure hardness?
A hardness test is typically performed by pressing a specifically dimensioned and loaded object (indenter) into the surface of the material you are testing. The hardness is determined by measuring the depth of indenter penetration or by measuring the size of the impression left by an indenter.
How Do You measure O-ring hardness?
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.2019-05-13
