Describes the housing (gland) dimensions for class A O-rings for general industrial applications conforming to ISO 3601-1, as well as housing dimensions for class B O-rings used on selected metric-dimensioned hardware, e.g. fluid power cylinder bores and piston rods.

This part of ISO3601 specifies the housing (gland) dimensions for class A O-rings for general industrial applications conforming to ISO3601‑1 , as well as housing dimensions for class B 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 ( d 1 and d 2), size codes (SC) and tolerances conform to ISO3601‑1 . Housing dimensions for the O-rings intended for aerospace applications that are specified in ISO3601‑1 are addressed in AnnexA. 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 terms “housing”, “groove” and “gland” are interchangeable, and their usage is a matter of local convenience. In this part of ISO3601 , the term “housing” is used exclusively.
