Includes our updated color-changing Dry-Pac ball system.

The blotting balls will gradually change from orange to green as they absorb moisture.

When the color of the balls is green it is necessary to change them with a new bag.

Replacement valid for all Hill PCP air pumps with Dry-Pac system installed.

One envelope of Dry-Pac balls is enough to completely refill the Dry-Pac cartridge.

Dry-Pac balls are vacuum packed and can be stored indefinitely as long as the vacuum remains intact.

Do not use pumps to fill your PCP air guns that do not have a condensate removal system. Water contains lime (CaO), and when it enters the tanks of PCP air guns, it causes multiple damages such as air leaks, metal corrosion, jamming, etc.
