SKU: BD521808 Category:


Even in temperature up to 400° F, these silicone O-rings will bounce back after compression. They have a round profile and are suitable for a wide range of static and dynamic sealing applications. All are sized to the SAE standard AS568.  This O-ring slips around the extractor spring to increase extractor tension for more reliable extraction. Eliminates the spring’s bounce to prevent malfunctions caused by the extractor slipping off the cartridge rim. Helps ensure positive, consistent extraction during rapid-fire sequences.
