 Product Description




These (K-cup coffee filter) style retainers hold 100% biodegradable EZ-cup disposable paper filter elements and make solvent recovery cleaner and more economical than buying expensive Wix 24003 or Napa 4003 replacement filters for your solvent recovery system. They are CNC machined form T6061 aluminum and held to the closest tolerances so that five pieces can be stacked inside a wix tube and be captured tightly by our end caps with no rattle. (End Caps and outside tube are not included in this kit)

This Kit is for 5 pieces of part # (24003KCFE1) filter element retainer with no spacers.

A kit with 2 spacers and 3 retainers is also available Click Here for more info.

Parts may also be purchased individually so you can stack them how ever you want. Click Here for more info.

  8. The Cat's Ass

    Mine seem to rattle a bit. Need a small spacier to take up the gap. I have found they work better if you fill them with Kitty Litter. We run lots of mil surplus ammo that is semi corrosive, so lots of cleaning, all the time. Great product and will probably buy another set for my 3 gun team if I can stop the rattle.

  9. Beautifully Crafted....Awesome Design!!!

    Posted by -Cam on Apr 20th 2017

    If you are truely looking for a no nonsense way to properly clean your fire arm and recycle/dispose of your solvent look NO further!!

    Fits nice and snug with no rattle, and functions WAY better than I anticipated.

    BUY IT!!!
