Aerospace Size Standard for O-rings

2019-03-06
WIP
AS568E
This SAE Aerospace Standard (AS) specifies the inside diameters, cross-sections, tolerances, and size identification codes (dash numbers) for O-rings used in sealing applications and for straight thread tube fitting boss gaskets. The dimensions and tolerances specified in this standard are suitable for any elastomeric material provided that suitable tooling is available.

ARP1233B
The purpose of this document is to provide the aerospace industry with standardized dimensional criteria for dynamic radial elastomeric O-ring seal glands. It is intended for use in conjunction with ARP 1231, "Gland Design, Elastomeric O-Ring Seals, General Considerations". This document establishes standard gland design criteria and dimensions for dynamic radial O-ring seal applications and provides recommendations for modifying these glands in special applications. There are no provisions in this document for anti- extrusion devices.

CURRENT
AS4088E
This SAE Aerospace Standard (AS) defines gland details for scrapers for rod diameters from 1/4 to 15-1/2 inch (6.35 to 393.70 mm) inclusive, corresponding to AS568 O-ring Dash No. sizes -108/-111, -206/-222, -325/-349, and -425/-460. The gland details herein allow the use of more stable, efficient and reliable scraper devices than MS33675 glands. NOTE: Scraper configurations are not specified in this document.

AS4088D
This SAE Aerospace Standard (AS) defines gland details for rod diameters from 1/4 to 15-1/2 in. inclusive corresponding to AS568 O-Ring Dash No. sizes -108/-111, -206/-222, -325/-349 and -425/-460. The gland details herein provide more space than MS33675 and sufficient to fit more efficient and reliable excludion devices. Exclusion device configurations are not specified in this document.
