ARP1802A
The backup ring is defined. The various types designed for use with O-rings in MIL-G-5514 packing glands, and MS33566 and MS21344 universal fitting installations are described. Guidelines are included for selecting backup rings and backup ring materials. Backup ring installation procedures and precautions are described.

ARP1833A
The purpose of this standard is to provide the missile hydraulic and pneumatic component designer with information learned, tested and substantiated in correction of problems and failures experienced with seals that are subject to the unique requirements of missile static storage and subsequent dynamic operational conditions. Missile hydraulic and pneumatic component designers have been handicapped by the absence of concise design criteria for two difficult sealing conditions usually existing in missile applications as follows: Static pressure condition - Low pressure for long periods in a cyclic temperature environment (i.e., long term storage requirements). Dynamic pressure condition - High pressures suddenly applied in an extreme temperature environment (i.e., operational firing requirement).

ARP4727B
This SAE Aerospace Recommended Practice (ARP) presents two BASIC language computer programs to promote and standardize the computation of installed O-ring cross-section deflection hereafter referred to as "squeeze" and the computation of gland volume. The two programs were written with line numbers and without use of any system specific BASIC commands to allow usage with as many systems as possible with a minimum of editing. The programs support entry of customary U.S. or metric dimensions.

AIR6079A
The purpose of this report is to provide design, application and maintenance engineers with basic information on the use of metallic Spring Energized sealing devices when used as piston (OD) and rod (ID) seals in aircraft fluid power components such as actuators, valves, and swivel glands. The Spring Energized seal is defined and the basic types in current use are described. Guidelines for selecting the type of Spring Energized seal for a given design requirement are covered in terms of friction, leakage, service life, installation characteristics, and interchangeability. Spring Energized seals can also be made in various forms and types, including face seals (internal and external pressure sealing types), and rotary variants too. These further types will not be discussed in this document, but many of the same principles apply for them as well.
