New Generation of Hill Pump "MK4"
I checked out hill pump web in order to order 4 pumps for my friends and myself as well,,, i found that they have produced a new hill generation, MK4 …it looks like a great pump,,,and i think it should be great,,,because their MK3 that i have had for almost 2.5 years (i think) was worked very great and very easy to pump ,,and Mk4 must be at least smoother than Mk3 .. who knows ??? ok,,i will buy and try it ,,,,

very nice info and useful. ..Thanks a lot…
the silica gel that came with the hill pump is working very well,,,
Yes, but so far the Drierite I posted above removes about twice the moisture as the Hill packs. The Hill desiccant in these is molecular sieve, not silica gel.
It also changes color from blue to pink when fully saturated AND it can be regenerated in the oven and reused, unlike the Hill packs which Manufacturers states it can’t be reusable/regenerated.
Because of this I figure one pound is enough for anyone to get.
I will store and collect the pink saturated Drierite in another separate glass jar and when the time comes and it’s full, I’ll do the baking/regenerate all at onetime.

Hi Hemn,
This is the main pressure O-ring I use, it very similar to the OEM green one.

This is the Value O-ring and is very similar to the OEM black one if you what it to be easier to pump down try the one above. I’m not sure it will last as long as the one below but it’s very easy to change if it goes bad.

These are the only ones I usually change, but I’ll repost here again if I can get the size on the others.
Again these are for the MK3 pump, does the New Hill MK4 use the same O-rings ?

Can you send all other o-ring links of hill pump ?
Dang, ,,,, ,, what happen to this thread, ,, , I thought I accidently stumble on a gay porn site ! :rofl:
I fill my Hill MK3 late last night with the Drierite and top off my 22 cricket when I bleed it off about half as much moisture came out of the pump compared to the Hill pack.
I used the foam from a small tin of pellets to hold the granules down so I can watch the color changing into pink.
Also a week ago I changed the value O-ring from the factory A90 to a 006 V75 Viton and the pump became easier to pump on the down stroke !

LOL…..that ought to do it Donny!
Oh – I thought it was metric. Never mind. 😆
That’s almost 8 inches right there SEcoda, you’re telling me yours is larger than that? We’re going to have to call you Lex Steele from now on. Warning do not google lex steele if you’re scared of getting your eyes poked from across the room.
Can you turn up a King Kong model for me on the lathe? 😛 That is a pee wee.
Thank god he’s alive Zonk! MK is only for airguns. What he needed was this
Sweet Hemn. My buddy bought a hand pump and filled his Bobcat once and sent it back. Damn near killed him.
Nice Hemn! Same amount of pumps just less effort as the Mk3?
