Crosman 600 reseal kit
Looking to find the right sizes for a Crosman 600 reseal kit. Would like to buy my own o-rings. So far I know that the valve body and piercing cap seal to inside of tube, both are 113 urethane 90. Hammer seal to valve is 014 urethane 90 o-ring. Also there is a breech gasket square o-ring, but do not know what size, what material, and if 70 or 90?. And I see at least two more other sizes also in a kit.
