Compressed Air Piping System, 1/2 inch x 200 Feet,HDPE-Aluminum Compressed Air Line Kit for Garage Air Compressor Accessories Kit Leak Proof Easy to install Garage Air Line Kit

There’s a lot of good stuff in this kit.I’m using this kit to replace the leak prone 3/8 inch air hose that goes from the corner of my shop to an air hose reel. The 3/4 inch hose in this kit will flow better than the old 3/8 hose, and the fittings will allow me to have multiple outlet points in the shop.I’ll be installing the distribution piping high up on the wall just under the trusses. This kit includes 200 feet of 3/4 inch pipe which is enough to go around the three sides of my 30x40 foot shop with enough left over to make drop lines from the ceiling to each of the T-Fittings in the kit. The lower priced kits I looked at on Amazon only included 100 feet of pipe, which isn't enough to do the job.Each of the drops will terminate on one of the five included terminal ports where I will install pressure regulators, air dryers, oil separators and gauges. One of the drops will be for my existing hose reel, and another at my work bench. Yet another drop will pass through the wall of my shop to an outdoor connector for servicing Ag-Equipment, trailers and my RV. This kit includes nearly every thing I need to distribute compresses air where I need it.I already have the air hose connectors and two of the pressure regulator systems that I need. The good thing about this kit is that I can shut off the valves on the termination blocks I'm not ready to use until I get the rest of the dryers and regulators installed. I will also use the valves to off the stations I am not actively using to help minimize leaks in the air hose connectors and tool connectors.I did purchase a 3/4 inch ball valve that fits this type of air pipe to add to my design. One end of this pipe system will connect to a line that goes to my sprinkler system. The additional valve will be in the off position except when I am blowing out the sprinklers. At some point I’ll likely replace that valve with a solenoid operated valve and program a custom sprinkler controller to automatically blow out the sprinklers on a specific date.The only thing included in this kit that I didn’t care for are the mounting clips. They just don't seem as durable as the other parts in the kit, and I suspect they will become brittle over time and break. I’m going to use regular metal pipe clamps to mount the air pipe to the walls. I know those will last a good long time.All in all this is a good kit that contains enough pipe, fittings and connectors to outfit almost any garage or small shop.

The holes in the aluminum blocks were not machined to the proper National Pipe Thread (NPT). Without NPT it would, in my experience and opinion, seal properly. I returned this for that reason.

I thought this would be a great system for my shop! Until the on off valves that go on the bottom of the air block will not open or close with out a bunch of force to make it move. Then I had one block out of five that completely stripped out on the top for the airline. Now I have to spend more money to buy a replacement block for something that wasn't manufactured properly.

This kit works. Kinda. After hours of fiddling with my system (130ft loop system with 2 drops and a ceiling port) I have it almost with no leaks. The piping itself is completely fine but all of the fittings are cheap and the blocks are tapped with the precision of a monkey. I got everything put together then had to take all the blocks off and retap all of the 1/2 ports because they leaked like crazy due to the horrible tolerances.Not to mention I couldn’t get spare parts if I wanted to because this is a 5/8 OD kit which seems impossible to get parts for.If I’d do it again I would spend the extra money for a maxline kit that just works.

This air piping system is great for the "do it all yourself" type guy. My husband was constantly dragging his air hose around in the garage for mechanic work, and then out to the patio for air tools on wood projects, then having to reel it all back in for storage. Having this system has allowed the hose to be attached to the garage ceiling with drops in different locations so that connections for whatever he is working on are quick & easy without doubling the amount of time used in preparation. You just cut the hose and use the connections provided to make your desired drop locations. He installed the entire system in about 2 hours. That alone makes it worth the purchase.On top of the convenience, the connections are good quality. We live in Vegas where humidity and corrosion are not necessarily an issue that we face, but the quality of the fittings seem to be such that it will not be an issue in more humid locations, either. So far, zero leaks.I deducted one star because the listing is a bit misleading. The size of the hose is outer diameter, not inner, so a 3/4" line is actually a 5/8" interior size....which is what you typically measure a hose by. They advertised as 3/4" ID. Despite the error in the listing, it works well and is a great kit. Just be aware of that.

i got this for my shop. It was fairly quick to install, and it was way easier to run vs steel pipe. i did have one leak, but it was just a loose fitting. i tightened it up and no leaks now

Check this product’s size. It comes in the mail and I’m excited to get started installing. So much so that I don’t even check the size. Now it’s too late. At the time of purchase it was advertised as 3/4” tubing. I see now they’ve changed it to say 1/2” (in most places in the description) and it is neither. If you look thru the pics, one pic shows metric measurements of 16mm ID and 20mm OD. I believe these to be correct. Be aware of this bc when you need something else that isn’t included in this package (a shutoff ball valve in my case) you’ll have a very hard time finding it in 5/8” ID. I’d look at a different kit than this one.
