MaxlineM3800 Master Kit, 1/2-Inch x 100-Feet

Installed it in my new shop. Went up easy and no leaks on the first pressure up!!

I utilized this product to build a multi drop header throughout my shop. I was hesitant at first as a welder (I’m notorious for overbuilding everything) and wanted to utilize steal black pipe. At the time the cost comparison between going that route and this route was huge and I decided to take the personal “psychological” risk of of using this product instead. Installation was relatively simple. It does take a little finessing to get the line itself straightened out as you hang it. Wouldn’t call it a two person job but a second set of hands would definitely help. Also a little easier to complete the task when the line itself is warm. If you live in a colder environment like it do, keep the heat up and the shop doors closed. The fittings this kit come are easy to install as well. The bevel tool is simple and self explanatory and I chose to use a little bit of Blue Monster Thread tape on each joint. I ordered additional T’s and 90’s from amazon as well to complete my drops so I have air wherever needed in the shop. Have had product in use now for approximately 3 months without issue fed by a dual stage compressor that I keep roughly 150 psi on (have individual separators and Reg’s at each outlet). There are no leaks and the lines hold pressure if outlet valve left on. My advice is to sketch out your actual plan for install and cross reference what this kit comes from with what you actually need. It does come with a generous amount of fittings, but depending on how complex of a system you wish to build, you may need more fittings. Overall, I am extremely pleased with the product, which exceeded my expectations. It is also much lighter than a conventional black pipe approach, meaning your need to fasten it is drastically reduced and you don’t need to worry about moisture effecting the longevity of the product given it’s composition. I would definitely use this product again and recommend it to others looking to do something similar in their shop/garage.

Acabo de terminar hace pocos días el sistema de aire de mi taller en la casa, hasta ahora todo muy bien, un poco caro su precio, pero si lo vale; muy práctico su uso queda muy completo en mi taller y sobre todo muy facil su instalacion me quite de muchos problemas, en comparación con la instalación de un sistema de tubos negros o de cobre este es mucho mas sencillo y flexible de colocar, muy contento

Neat product, perfect to bring air in every corner of your garage, a bit frustrating to get the curve off, but other then that wow.

I just finished our 3rd installation of Maxline in our business and at my home shop and now I'm planning an expansion in the shop. I keep coming back to the Maxline product because it works, it's economical, it's easy to install & maintain and it looks great. All of our blue lines are installed on the outside of the sheetrock where they're easily accessible and we use the optional black plastic clips spaced anywhere from 2' to 4' apart. Our CFM requirements aren't very high so we've stuck with the 1/2" pipe size which contributes to the economy of our systems. At the business, some of the air machines are over 100' from the compressor and I wasn't sure if they were going to get enough air so I had planned to put in a header tank in the distant machine room to act as a ready reserve, but it was never needed. At the home shop, the most distant tire hose reel is 80' from the source and some of the spray equipment might need higher flow, so for the expansion phase I plan to complete the loop back to the source. In this way, air can travel both directions around the pipe to wherever there's a need. The attached pic shows this manifold, which comes with the Master Kit, and you can see the available 2nd outlet on the front that's plugged off for now.Tip: Use thick Teflon tape like Maxline sells (assuming they still do) and plumber's paste on all of your NPT connections. I like to fold the tape in half (easier if you use 3/4") and then make 2 wraps nice & tight right at the start of the threads. Then apply the paste, just a bit, around the tip of the threads and back about 1/4". I use the blue paper towel shop cloths and cut them into fourths, then fold those down to a small size and use them to clean off the paste around the joint--you can refold these little pieces a few times before tossing it and grabbing another one.If I had one suggestion for Maxline it would be this: Please redesign your fittings to be less restrictive. Yes, I understand the Bernoulli principle and the Venturi effects involved, but there's still some static pressure caused whenever you have a restriction in a flow tube. I realize that the fittings must go inside of the Maxline tubing and I just wish that these bits could be a little thinner through there. In some cases this will prompt people to jump up to the 3/4" or even 1/2" option but so far we're getting good service from our 1/2" system, at least until our CFM requirements increase.You may find some frustration with straightening the coiled tubing. I've worked it on the floor with a helper after cutting it to the proper length and I've also used Maxline's beautifully made aluminum roller system straightener. The device helps but not as much as hoped and frankly I think the design of the wheels could be improved. You can build your own using a plan that's available on Maxline's website but I've not tried it although I would probably do so if I hadn't bought this one on the assumption that it would work better than it does. Eventually though, you work on the tubing enough that you're ready to settle for slight straightness errors and then you install it and it turns out to be better than expected. If you work with a helper, you can make minor adjustments after the tubing is snapped into the clips and then you stand back and realize that it looks pretty good.
