Qick and easy place to get much needed replacement seals. Priced right---shipped quick too! I would (and already have) order from Dennis Kirk again. (I shouldn't have gone browsing---now I am about ready to buy a new helmet!) Thank you Dennis Kirk!
I always use this conventional design seal because the all-rubber Leakproof brand leak. These don't leak. Always polish out nicks and pits with 1000 grit sandpaper and tape over sharp edges before installing.
