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.
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.
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.
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 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.
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.
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.
.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
The ASME B16.21-2016 standard covers types, sizes, materials, dimensions, tolerances, and markings for nonmetallic flat gaskets. These gaskets are dimensionally suitable for use with flanges described in the referenced flange standards.

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.
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
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.
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.
Contact profilometers utilize a stylus that runs over the surface of an object to allow for measurement of various profile parameters. There are two general types of contact profilometers: Skidded and skidless.
