Scope
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.
Rationale
This specification was created to define gland dimensions for rod scrapers originally using 1 backup width basic groove dimensions to MIL-G-5514F, later AS4716. The 1 backup width provides good part stability along with improved performance compared to the previous MS33678 standard. The significant differences between this standard and AS4716 are the clearance on the atmosphere side of the gland and the size range -104 thru -111 and -206 thru -209 have been extrapolated to provide larger cross section parts than AS4716 allowed.

Issuing Committee
A6C2 is responsible for the development of standards, processes, and practices related to Seals, Scrapers and Bearings used in actuation systems for Commercial and Military air vehicles. The panel provides a forum for government engineers, prime contractors, OEMs and suppliers to exchange technical information, regulatory updates, recent technology developments, issues related to system development and in service operation and lessons learned.

* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
