Some people prefer silicone because they say that it withstands more abuse, and some people say buna does. From our experience, Buna is by far the way to go with paintball. It is good in a wide array of temperatures, can last a long time, seals great, and is nice and inexpensive.And what is the 70 and 90 durometer thing you keep mentioning?The 70 and 90 durometer is simply a measurement or the hardness of the material. Different hardnesses are better used in different situations. All of our kits follow the marker manufacturers recommended durometer for each o-ring. Your kit will have some o-rings in 70 and some in 90 or other durometer, but they will be the same hardness as the ones currently in your marker already, respective to each o-ring.Get the full Tippmann 5 parts kit HERECheck out the manufactures website HERE
