Fluid power systems — O-rings — Part 2: Housing dimensions for general applications
Hardcopy , PDF

26-11-2025
This document specifies the housing dimensions for classA O-rings for general industrial applications conforming to ISO3601-1, as well as housing dimensions for classB O-rings used on selected metric-dimensioned hardware, e.g. fluid power cylinder bores and piston rods. These O-rings are for use in general hydraulic and pneumatic applications without and with anti-extrusion rings (back-up rings). The dimensions of the O-rings (d1 and d2), size codes (SC) and tolerances conform to ISO3601-1.
This document also addresses different design approaches in industry, and this is reflected in the table structures for hardware dimensions. Using the O-ring as a starting point to design the optimal hardware dimensions is reflected in .
NOTE1 It is expected that O-ring housing dimensions for special applications be agreed upon between the O-ring manufacturer and the user.
NOTE2 The term “housing”, in this document, is used to describe the groove or cavity, into which the O-ring is fitted, and the mating surface, which between them confine the O-ring.
