ROK GC Part - Silicone Shield
Replacement Silicone Filter Shield for your GC.
This part is one of four parts included in the ROK GC Conversion Kit.
Important Information regarding Silicone Seal Sizes
ROK recently made a minor change to the water chamber, to help create a better seal.
The water cylinder on the right of the photograph below has a lip on the bottom, this is the original GC Water cylinder - the unrigged silicone shield was supplied with it.
The water cylinder on the left of the photograph below is flat, this is the newer GC Water cylinder - the ridged silicone shield is supplied with it.
Please note that this is a very subtle change and the two silicone shields are pretty much interchangeable.
Please check your cylinder and order Thick for the newer cylinder (left) or Thin (non ridged silicone shield (right)
