An attempt has been made to consider all features of seal ring design including configuration, materials, hardness, dimensions, surface finishes, surface treatment, leak testing, and general quality. In addition to this, allowable cylinder breathing and general quality requirements of mating hardware are discussed. Also, at the end of this report, there is a brief paragraph on other types of seal rings.

This SAE Aerospace Information Report (AIR) provides basic information on the use of slipper seal sealing devices when used as piston (OD) and rod (ID) seals in aerospace fluid power components such as actuators, valves, and swivel joints, including: The definition of a slipper seal and the description of the basic types in use. Guidelines for selecting the type of slipper seal for a given design requirement are provided in terms of friction, leakage, service life, installation characteristics, and interchangeability.
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.

This SAE Aerospace Information Report (AIR) contains a description of the design approach, the calculations, some comparisons to alternate SAE Aerospace Recommended Practice (ARP) documents, and the background information used to generate the standard face seal gland dimensions specified in AS6235. NOTE: This AIR should be read in conjunction with AS6235. In some instances, the information contained within AS6235 is repeated for clarity.
The purpose of this specification sheet is to set up a standardized part numbering system for O-rings procured to MIL-P-83461 for use in straight thread tube boss fittings.
This document establishes general gland design criteria for static and dynamic O-ring seal applications used in fluid systems and at fluid pressures common to the aerospace industry. Detailed discussion of design criteria and tables of recommended gland dimensions are contained in the documents listed in Table 1. S.I. unit conversions for U.S. customary units have been provided for reference purposes.

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.
This document recommends standard gland design criteria and dimensions for dynamic radial O-ring seal applications specifically for engine and engine control systems operating at pressures up to a maximum of 1500 psi (10342.14 kPa) and provides recommendations for modifying these glands in special applications. There are no provisions in this document for anti-extrusion devices. NOTE: The criteria set forth here are similar to but not identical with those in MIL-G-5514 and AS4716. This document is not intended to replace MIL-G-5514 or AS4716 for hydraulic applications.
