Notes: When ordering parts made with a military, AMS or NAS specifi cation material, see the section on ordering.
(1) Extra charges may apply for testing and documentation.
(2) These temperatures are limits for particular tests required by the specifi cations, but they do not necessarily represent operating temperature limits.
(3) Inactive for new design, refer to MIL-P-25732. See discussion on “Temperature” in the Basic O-Ring Elastomers Section (II)..
