Elastomer Compatibility Considerations Relative to Elastomeric Sealant Selection

2019-12-16
WIP
AIR786C
This document contains data relative to the chemical nature of aerospace fluids and relates each to its empirical effect upon elastomeric components. Since the compatibilities of elastomers are determined by the compounding as well as the nature of the base polymer, the elastomers considered are limited to finished compounds for which material or performance specifications can be referenced.

CURRENT
MA3445A
These products have been used in contact with air and a wide variety of fuels, lubricants, specific hydraulic fluids, and a variety of gas turbine engine lubricants, including higher thermo-oxidative stability (HTS) lubricants, including those conforming to MIL-PRF-23699 Class HTS, MIL-PRF-7808 Grade 4, and AS5780 Class HPC; however, usage is not limited to such applications. This material type has a typical service temperature range of -20 to +400 °F (-28 to +204 °C). These products are not suitable for use in phosphate ester based hydraulic fluids. Each application should be considered individually.

WIP
ARP1231C
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.

Storage of Elastomer Seals and Seal Assemblies Which Include an Elastomer Element Prior to Hardware Assembly

CURRENT
ARP5316E
This SAE Aerospace Recommended Practice (ARP) addresses the general requirements for data recording procedures, packaging, and storing of elastomeric seals and seal assemblies which include an elastomeric element prior to the seal being assembled into hardware components. It applies specifically to those elastomeric seals and seal assemblies packaged shortly after manufacture. The storage period prior to installation of the elastomeric seals and seal assemblies into hardware components is commonly referred to as shelf life. The information contained in this ARP is intended to be utilized by those organizations who do not have specific requirements or recommendations already in place for the control of elastomeric seals and seal assemblies. This ARP can be specified in control, storage, and procurement documents.

AS5316
This SAE Aerospace Standard (AS) specifies the general requirements for data recording procedures, packaging, and storing of elastomeric seals and seal assemblies which include an elastomeric element prior to the seal being assembled into hardware components. NOTE: The requirement for packaging is an integral part of the controlled storage procedure and provides a means of positive product identity from the time of manufacture to the time of assembly into a component.
