Find the most up-to-date version of SAE AMS at Engineering Aerospace Material Specification also called AMS can exhibit exceptional resistance to heat, aging, weather, ozone, oxygen, and sunlight, as well as. For o-ring applications requiring resistance to heat and a broad range of chemicals, Anchor Rubber carries Viton O-Rings including AMS Viton, FDA Viton.

Sorbent Pads, Rolls, Drum Top. This fee does not cover shipping costs. Filament 72276 Strapping Tapes.
Adhesives and Tapes — Others. This is backed up with long-term stress relaxation data at high temperatures. Orders must be placed prior to 3PM Eastern Time. Landing Gear and Hydraulic Fluids.
Hand Care — Others. When carrier USPS is selected, we cannot guarantee this option. This ensures sealing integrity and contributes to long seal life, helping maximize aircraft flight hours. Duct, Foil and Masking Tapes. Since then, it has undergone a word-for-word conversion to AMS-R and presently is being updated to include Reference Oil aging 726 longer term compression set test requirements.
A brief summary of the principal advantages offered by the new APA polymers is: More importantly, the ability for fluoroelastomer O-rings to seal at low temperature, as determined by this method, is predominately dependent upon polymer composition.
This advantage is particularly evident in the static O-ring seal testing.
As the sealing material approaches its glass transition temperature Tghardness increases and ama ultimately loses its ability to remain flexible. It is particularly important to differentiate between materials in aerospace engine applications requiring high temperature performance combined with low temperature capabilities, something older generation FKM materials cannot achieve.

EAR – All Seals
The ability for O-rings to seal at low temperature correlates closely with glass transition and temperature retraction. Clips, Clamps and Plugs. For more information on these O-0rings, please consult the AS cross reference chart. At low temperatures the modulus of an elastomeric sealing element increases as the temperature decreases.
However, engine manufacturers are demanding reliable sealing at even lower temperatures as well as at high operating temperatures and with the ability to provide long service life in the now universally-used HTS oils.
Bumps your order to the front of the line to be picked, packed, and shipped out. Sealing and Splicing Tapes. Published on May 31, 6: Perhaps nowhere was the reality of this intractable physical phenomenon more painfully evident than the tragedy that befell NASA’s Mission L in the Challenger disaster.
Special Pins and Bolts. Fluid Resistant and Low Compression Set.
Fluoroelastomers target aerospace sealing uses: Part 2 of 2
The processing benefits of APA technology were highlighted and several of the advantages of these new products have been illustrated with supporting data. Crown Head Solid rivet. Discussion of low temperature property testing and sealing Low temperature flexibility is strongly influenced by the level of VF2 in the polymer, even for those polymers in which PMVE is used to lower the glass transition temperature. Preservative and Lubricating Fluids Xms Sealants.
The very specific combinations of main monomers which provide the excellent balance of fluid resistance and low temperature flexibility exhibited by compositions like FKM-GLT was determined in the mids.
