Manufactured from black-colored EPDM elastomer and rated at an 80-durometer hardness, these O-rings meet the ISO BS 3601 imperial standard 111 size (equivalent to SAE AS568-111), providing reliable sealing performance. Genuine Apeks BS-111 size O-rings are provided in a paper envelope, intended specifically for use with Nitrox Ready and Oxygen first stages from Apeks.
