clip on valve seals

hello people; I'm new. Any tricks in getting them off or do you just replace them? Are all the valve seals on KZ's clip on?

Hi Ibby

They should just pull out. They may be hardened from age. You need to replace them, so don't worry about destroying them. Just grab on the plastic and pull /tear away. Just make sure your not grabbing on the metal guide they are attached to.

Cheers

they just push on buy more than likely hardened from age best to replace with viton seals let me know if i can be of any help locating the proper seals.
