Fluid Power Systems - O-Rings - Part 4: Anti-Extrusion Rings (Back-Up Rings)
Also Known As:
The DIN ISO 3601-4 standard outlines the dimensions and tolerances of various types of anti-extrusion rings. These rings are designed to prevent o-rings from being extruded or damaged under high pressure or extreme conditions in fluid power systems.
The standard specifies five different types of anti-extrusion rings: spiral type (T1), angle cut type (T2), solid type (T3), angle cut concave type (T4), and solid concave type (T5). Each type has specific dimensional characteristics and tolerances that are critical for their proper function in preventing extrusion.
It is important to note that these anti-extrusion rings are intended for use with specific o-ring sizes as specified in ISO 3601-1 and compatible housing dimensions defined in ISO 3601-2. The standard ensures that the anti-extrusion rings and o-rings are properly matched to provide effective sealing and prevent extrusion in fluid power systems.
