Aerospace Size Standard for O-Rings

2020-09-29
CURRENT
AS568F
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.

O-Ring Groove Design for Packing Preformed, Elastomeric O-Ring Seals, Static, Axial Compression, Metric

2020-08-11
WIP
MAP3439A
This recommended practice provides the design criteria for static elastomeric O-Ring seals used specifically for engine and engine control systems. It provides axial compression (face type) groove dimensions for aerospace metric O-Rings sizes specified in MA2010. The conditions considered to formulate the design criteria are also described, e.g., seal squeeze and groove volume to accommodate O-Ring volume swell.

Aerospace Rod Scraper Gland Design Standard

2020-07-22
WIP
AS4088F
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.
