Weihrauch HW100/101 fill probe O rings x 2
Replacement O rings for a HW100/HW101 fill probe. This is for a pair of O rings (2).
If your probe leaks air/will not seal properly when when you are trying to fill your rifle it may be time to replace your probe O rings.
It is a good idea to use a small amount of Abbey SM50 on your probe O rings to prolong the life of your O rings.
This listing is for O rings, not the actual fill probe.
The picture is a generic picture of some O rings, not the actual O rings you are buying.
