Decent desiccant kit - Sun Optics Airgun Scope Mount Desiccant Kit For High Pressure Hand Pump

I bought this for my new Benjamin PCP hand pump since I live in the south and humidity is high. Installation was very easy and quick, although they do not tell you to use any sort of Teflon tape on the sealant on the threads. But upon removal of the filter that this replaces I noticed that there was no tape or sealant on this fitting either. I guess it's not needed. My only disappointment with the kit is that where the inlet filter was fastened to the top of the clear plastic bulb, it has cracked from being over tightened by the factory. It has not affected the performance of the filter at this time. I would recommend this to anyone wanting to be sure they don't get moisture in there new PCP cylinder.
