DIY Fill Probe Protection

[Bobmart]

When I got my PCP airgun that utilizes a fill probe, I thought about a way of protecting the probe and o-rings while keeping the probe attached to my air tank hose. I came up with the idea of enclosing the probe inside a plastic box. I had an empty 18650 battery plastic box that looked perfect for the job.

I placed the probe against the box's bottom half, drew a line on either side of the probe and cut out a notch with my pocket knife. I "guesstimated" the depth of the notch and it turned out fine. I repeated the process on the box's upper half.

I adjusted the width of the box notches so the assembly would fit snugly inside the notches at the junction where the probe attached to the male foster fitting adapter.

Now I can leave my fill probe attached to my air tank hose without fear of damaging the probe and its o-rings.

I'm sure any similarly-sized "clamshell" plastic box will work with this idea. Give it a try and protect your fill probes while keeping them handy. Bob

Excellent idea! I have long believed that airgun people are very inventive.

Great solution! This will replace the sandwich bag I have been using.

That's good.
Can I make an extra suggestion?
Yes, OK Mark, go ahead.
Well, I put an extra, slighly bigger O-ring over the filler probe and snug it down as far as the nut.
That means that the brass nut is cushioned from the edge of the filler port on the cylinder.
I hope this prevents marking and also do it on my HW100.
Note that the tip of the FX probes are not tapered, so take care when inserting them.

Bobmart,
Like they say "any idiot can build the second one". Saw your GREAT idea and here is what I came up with. I had this little containers and put them to use. 





Thanks for sharing your idea with us.

Clear plastic tubing works great_ add a little silicon grease and it stays secure and slick. "Wax on- Wax off"

It was a pleasure sharing my DIY idea with my fellow airgun enthusiasts. I've enjoyed reading your posts and seeing what you've created. More posts to come.

I use a rubber nipple on most of my fittings.
