Air dryers for hand pump

[yeagger]

So what would you guys recommend for making the air dryer before it goes to my pump and in into my gun. I live in Washington State so it's always raining up here. And I'm beginning to worry now that I get it more expensive guns and that going to shorten the life of my tubes because of us. I have a Benjamin pump so I will have to make a custom whatever.

Just add a filter to the line. Like this one

Have a look at :
http://www.airriflepump.com/acatalog/Air_Rifle_Pump_Universal_Dry-Pac_Kit.html#SID=11
and
http://www.airriflepump.com/acatalog/MK4-Dry-Pack-Kit.html#SID=11
These are for Hill pumps, but it might be possible to adapt. Look around on their site you will find diagrams.
The one mentioned by Erik is an on line filter not an air dryer (unless I am missing something)

The last time I was out shooting it was raining and this that a lot. I'm just trying to keep my guns safe for the long run.

Do if any one cares shat I did: m.harborfreight.com/inline-desiccant-dryerfilter-68215.html and went to my local hardware store for 1/8 npt male to 1/4 female npt and back again.

I have the air drier on my Hill pump and the beads, supplied by Hill, never seem to change color (they remain white). Not sure if the air in my house is that dry or if the beads just aren't removing any water. I have had to recharge (dry) the beads on my shoebox which are different purple (dry) to pink (wet) and maybe more hygroscopic.

Drop one in water and see what happens.

I used air compressor in line dryers I got from napa. They came in a two pack and with a brass adapter worked great for me when I was pumping!

You can call Sun Optics, the manufacturer of the Benjamin pump and request an air filter for the hand pump. If I recall it was $25.00, it works pretty well and you can open it up to dissipate the moisture trapped inside when it is saturated.

My Discovery was having excessive moisture issue in the airtube that caused it to rust right around the o-ring seals that required an airtube replacement and so far the moisture seems to be working well.
