Urethane O-Rings
This week I’m working on a 2005 Proto Matrix by Dye. These are pretty chunky paintball markers like many from this era but they are nicely made and simple to maintain.
Now what I find with markers of this age is the deterioration of any urethane o-rings used. They get sticky or even turn to jelly depending on their age and exposure to lubricants. These ones were just soft and sticky. In extreme cases I’ve had urethane o-rings ooze out like plasticine when a marker is aired up or fired.
So if you have a paintball marker that’s over 15 years old containing urethane o-rings. It might be a good idea to check them if you plan to use it again.
