This bottle cap is prefect for protecting your air system or co2 threads, and it can hold an extra o-ring incase the one you have fails. dunno what else to say really, it does what its supposed to do protect your threads from getting damaged.
need more words: basub dahsda siso djao jsdo jsoiajo sjd oajso do
Buy it, its strong and well contructed, protects your threads, hold a spare o-ring and comes in different colors, what more could you want!
