This o-ring size reference contains size and nomenclature information for the most common global o-ring standards. The information is organized into three 

2 days ago · The Global O-Ring and Seal Size Reference Chart covers the AS568 O-Ring Sizes published by the Society of Automotive Engineers (S.A.E.), and includes the Extended Sizes in the 400 Series. Dimensional tolerances for all AS568 o-rings offered by Global O-Ring and Seal are in accordance with ISO 3601-1A. The purpose of this chart is to specify the

This design quick reference guide is intended for use in specifying O-ring and groove dimensions for static applica- tions with pressures less than 1500 psi.

Size:Standards are specified by their ISO 3601 dash number. O-Ring size is defined by inside diameter and cross-section (width) and is listed in both fractional and decimal dimensions with tolerances. The standards range in I.D.'s from .74 mm to 658.88 mm and cross sections (widths) from 1.02 mm to 6.99 mm.

O-Ring Gland Fill %O-Ring Volume) / (Gland Volume) Gland volume vs. O-Ring volume. About 25% void space or 75% nominal fill. Need space in groove to allow for volume swell, thermal expansion, and increasing width due to squeeze. Narrower groove for sealing vacuum or gas. O-Ring can extrude into clearance gap or get squeezed in two directions.

O-rings Technicaldetails Design O-rings are a simple but very versatile seal. They are most commonly used for static applications, and for pressures over 1500 p.s.i are used with back up rings (See Section). O-rings with sizes to AS-568A are available in NBR 70 and 90 Shore A compounds and in FKM 75 Shore A. O-rings in NBR and FKM are suitable
