Seal kits are around 35bux at Pyramyd. Videos on YT show how to do it.

The header here is a sponsor of ours and 1/2 that price

You just have to order a Hill MKIII kit and it's easy to rebuild. Hardest part is breaking it loose the first time. After that you do NOT need to make it that tight. It will NOT leak if you tighten it as hard as you can by hand. If you use a wrench don't tighten it as tight as it was. You could mash the rings. I've rebuilt many pumps and Hills have never even needed it. I just wanted to see if there was any rust and rebuild and learn. All seals were fine. I use 100% plumbers silicone grease. Sparingly but enough to cover rings completely. The static or friction bearing orings need a little more. Lube not just the rings but the surfaces they glide on. They're instructions to be found on Youtube but if you're not confident I'll gladly rebuild it for free. You just pay shipping to Pennsylvania & back. Everyone was selling the rebuild kits for $35.00; but now one of our sponsors, "The O-ring Store" has a header on The classifieds. It leads to his eBay page and you can pay with any credit card. Just click where it says pay pal but you don't need pay pal. It'll give you the option of using any card. You can't beat $14.95 as the original price of $35.00 is insane. I swear by Hill pumps; but my next one may be a G6. Much cheaper, and comes with 5 full rebuild kits. There's also a new one called "The Brute" or Brutus, something. It's supposed to be built like a Hill with tight tolerances and very well made for the price. We're going to see a lot of new pumps & compressors coming out. You can't go wrong with any model Hill. I find pumping to 2K easy peasy. 3K a little harder. The G6 and some other pumps go as high as 4-4500psi and are good for high pressure big bores. I'd hate to have to pump that high every 2-4 shots and I don't know how long a pump that goes that high will last between rebuilds. 3K is good enough for me at the highest.

Email me if needed jamesdingle18@yahoo.com 15 pages of 100% positive BOI and will gladly rebuild your punp for free. Just buy the kit, a $4.00 container of 100% Silicone grease, & pay the shipping. I'll have it as good as new. You should learn yourself though in case you ever have to rebuild in emergency and need to know how. I keep 3 rebuild kits on hand. I theoritically have enough for a lifetime. The extra G6 or another Hill I want is just in case of a catastrophic failure, bended rod, run over or something.

James, have you considered...

April 20 2017, 10:42 PM 

... maybe putting together a YouTube video of your own, showing all the steps with your tips thrown in, on a complete disassembly & rebuild of the Hill mk3? I'd love to view & save that one!

Sir, I've wished i could, as I've learned much from KW, JWR,

April 21 2017, 11:54 AM 

Crickets old videos and such. First problem is I have no camera. 2nd slight problem, is I'd have to have Wife edit and down load as we did NOT have computers in the 70's & 80's. My Kindergarten 5 year old is being exposed to words I never heard until 4-6th grade and all kinds of Computer knowledge. So point is I'm not very adept at the making although I am a very patient descriptive teacher.
Now, I personally haven't checked You tube to see if it's already been done; but I would think it has. There's not many improvements you HAVE to do to any Hill. You CAN upgrade the o-rings. There's many others on here more qualified than I to give that info. Consider that all Hill Kits were $35.00 for years. Now, they are sold for $14.95 and they are the SAME quality o-rings. IF one were to use the absolute best o-rings for an entire rebuild, i.e. best friction/heat bearing static rings, and best hardest sealing non static/friction bearing rings for pure air seal, I would think all top notch possibly custom slightly over sized ones would cost the $35.00 that the original over priced kit cost. In reality, I've owned 4 Hill pumps and NEVER had to rebuild ONE, EVER! I did take it down, inspect for rust, o-ring wear, relube with 100% silicone grease, and IF anything needed a super fine polishing did that also. I've never had one fail. Now, Benjamin's, sorry to say but I was rebuilding 1 of the 8 I've owned at least once every 2 months. Tolerances just are horrible and inferior o-rings.
Other improvements to Hills. I have aftermarket parts from a Russian eBay seller (Vadim Sorokin) and HE is the only person I found to have extra brass pistons with dual seals. A o-ring and a teflon guide. You get 1 extra set of those also. The ring and teflon guide, only 1 new brass piston. It also comes, to my surprise, with a Teflon plunger that the cone spring seats. I STILL have not found a exact cone spring replacement and I NEED a few badly (just in case,) Long story short, I was disassembling my Hill which did not even need it and the rod fell out, landed on brass piston head and bent stem slightly. I straightened it and continued rebuild. No problems at all now but I have the extra piston in case that stem ever fails due to bending and bending back in place.
There's MANY things I'd love to put on Youtube. Shots no one would believe unless filmed, documentaries on certain subjects, info I have to share. Mainly I use the computer to learn. To me, it's a free College course. Quick example. Civil War Doctors had 2 years of Schooling. I've had no Cadavers to dissect but my knowledge from computer and modern age medicine theoretically puts me ahead of a Civil War Doctor. At least I'd know how not to infect you worse while amputating and I'd also have a better chance at getting you to live through it all with little to no infection. Thanks to our Friend The Maggots." Weird, but true. Change dressings often and they only eat the dead flesh preventing Gangrene. So, yeah, I guess Hill pumps are easy.
Back to pumps. seems some very good ones are made in Philippines mainly by hand and brass.
This G6 https://www.amazon.com/Air-Venturi-Hand-Pump-4500/dp/B00TGC9ZPO/ref=sr_1_fkmr1_3?ie=UTF8&qid=1492787821&sr=8-3-fkmr1&keywords=4500+psi+hand+pump+Brute is one I really want. From Pyramyd you get it with 5 full rebuild kits, foster fill adapter, and priced under a hill. I've heard NO complaints from owners here on Yellow.

This little guy looks interesting if you have the time. I can pump faster by hand I think, and i don't know about quality or longevity. Point is, there's a market and new items will be coming. I'd personally like to see Tom Kaye make a Shoebox model with every possible NEEDED upgrade, or offer them as customers request, and beat the competitions price. I'd buy a hardened rod, self lubricating no rebuild pump. I don't need belt drive, I don't need a small computer fan on it when I', running a floor fan that pushes 20x's the air flow over the unit that the little computer fan ever could. I mean, why pay for what you don't need. I understand money is made by selling rebuild kits and upgrades but hey, a happy customer can easily talk 5 Friends into a product. eau, I'd LOVE a Bauer. I don't need diver quality air. I need a compressor that will last a lifetime with little maintenance. Hill pumps are daily affordable and seem to be built for life. There is NO doubt, I did, and anyone, would shoot more often when they own a tank or compressor. I shot way more often when I had tanks. If I had a decent compressor and a brand new Great White from Joe Brancato I'd be set for life and shoot way more than I do. I'd also be seriously considering Air Guns tuned for serious power in .257 & bigger. I stay away from them and search for a .22 or .25 that can retain at least 18FTLBS @ 200 yards because I'm not pumping a .257 or bigger every 2 shots. And unfortunately until they build a 1000cc or bigger 4500psi fill double carbon fiber tank big bore that can produce at least 10 regulated shots with a spread of 20fps or less, then tethering is still the way to go for big bores.
You really want a video from me? I'm much more of a writer than a talker and I learn best from reading; but I understand some learn best from seeing videos. If I had a Camera, I'd do it for you. I think my phone only has 2 minutes of recording on it. It's about a 15 minute job to clean, relube, do right. Either way. People here have been kind to me and I'd gladly fix any pump for anyone for free.
Disclaimer: To the fellow that said I butchered that gun I sold him. I told you I used JB weld to hold that scope mount rock solid. Not to look pretty. It worked as I intended, no creeping whatsoever and I told you about it. You complained, I could of at least did a neater job. You kept the rifle because it was as accurate as I said. Pretty doesn't matter to me, for me. If I ever rebuild a pump, refinish a stock, reseal a PCP, etc, I would guarantee perfection on my part or I'd pay for damages or buy it out right. This obviously doesn't include damage from shipping which is why you always open the box BEFORE the courrier drives away and have insurance. Yeah, I owe Yellowforum and some if not all of its' good hearted giving members. So if I can ever give back, I will gladly. One day I'd like to own new Grizzly metal machining equipment and build my own projects. A pump is one of those things. That's a new topic I'll start, but think of the unknown talent here & everywhere. That fellow that just built "Big John" and the smaller tank valve. He is a MASTER machinist that I'd never heard of before, but obviously capable of building anything. Dave G. made and sold guns at a third of what he could have asked & gotten for them. Lots of giving people here.

Note, I have full diagrams of Hill disassembly and rebuild. If anyone can't find them online I'd gladly send copies via email or snail mail.

Good old Pennsylvania. I appreciate the offer because

as I'm thinking about this, it comes to me. To make a GOOD video, you need more than a tripod or any old friend to hold and film. You really need a real Camera Man to get it done right. Also, good luck in getting it done right in one take.
