DIN 705 is a standard number used to describe an O-ring. An O-ring is a metal ring with a threaded inner section that is used to connect pipelines or hoses. The O-ring has markings on it that allow for precise adjustment of the connected parts, which allows for optimal system performance.
DIN 705 fastening group
DIN 705 rings are most often made of stainless steel and belong to the stainless fastener group.
Materials for the manufacture of DIN 705 washers
DIN 705 rings are made of the following materials:
- Stainless steel grade A2. Steel grade A2 allows the fasteners to be used at high temperature extremes and in aggressive and humid environments.
- Steel that can be additionally coated with zinc. Zinc (Plated) protects against corrosion if the fasteners are to be used in aggressive environments.
Application range of DIN 705 rings
The O-ring can be used to regulate the pressure of a liquid or gas in a system. To select the optimal O-ring, it is necessary to take into account the size, type of connection and other technical parameters of the system in which it will be installed.
