Backup rings provide extrusion resistance and may be used with most elastomeric O-ring seals. This guide follows the Back-Up MS28774 scarf cut dimensions and will discuss the dash number, (ID), tolerances, thicknesses, and gap.
Back-up rings provide extrusion resistance and may be used with most elastomeric O-ring seals. This guide follows the Back-Up MS27595 dimensions and will discuss the dash number, Inner Diameter (ID), tolerances, and thicknesses.
JIS B 2401 is a Japanese Industrial Standard for O-Ring sizes. This standard is categorized into four series based on their application.
Series P = Dynamic sealing ; Series G = Static sealing ; Series V = Vacuum ; Series S = Slim hardware
This "elastomer cheat sheet" discusses the properties of the most common types of o-ring elastomers.
Learn about the thermal properties/ranges, advantages and disadvantages, and chemical resistances.
.As a percentage, O-ring squeeze represents the measurement of the deformation of a seal when compressed by mating hardware. This guide will walk you through the 4 simple steps to calculate O-ring squeeze
Parker's 5-Dash series of o-rings are classified as commonly used o-rings sizes which do not fall in the AS568 line of o-rings and are also not true “metric” sizes.
Failure modes are the ways, or modes, in which something might fail. O-ring failure modes that contribute to equipment failure cost the customer time and money.
The AS-568 O-ring sizing system was developed by the Society of Automotive Engineers (SAE). It utilizes dash " - " to refer to standardized O-ring sizes. The reference system allows engineers to prototype or test designs in a standardized way.
ASTM D2000 is a very useful tool to quickly specify requirements for O-ring materials and decipher their description. This guide will discuss what the specific callouts mean.
The DIN 3771 o-ring standard is issued by The German Institute for Standards (Duetsches Institut für Normung). This standard identifies O-Ring sizes by the Inner Diameter x Cross Section.
The O-Ring gland (also known as O-Ring groove) is a very important design feature for manufacturing both efficient and cost-effective O-Rings. The groove can be a variety of shapes; anything from triangular, rectangular, or dovetail.
This tech bulletin aims to provide a resaonable basis for calculating reciprocating O-ring seal glands. In addition, you can find a diagram for industrial reciprocating O-ring packing glands.
