    Customers like the performance of the auto part. They mention that it works well and mounts nicely. Customers also appreciate the ports that allow them to route horn, air springs, tank, and gauge.

    "Works perfect and very high quality. Paired it with an onboard compressor in my JKU. Highly recommended!" Read more

    "...I plumbed them with 3/8" air hose and they work fine...." Read more

    "This manifold has worked really well for me. I used to connect my two Viair 444C compressors, pressure switch, and main hose output...." Read more

    "...This guy worked great and I love the mounting bracket. You can change the position that it attaches to the block. So cool." Read more

    9 customers mention9 positive0 negative

    Customers like the appearance of the auto part. For example they mention it has a great design, a clean finish, and does away with the maze of tubing under the hood. Some say the bag was torn and missing a bolt.

    "This manifold is super well made, and it's unique -- it comes with a bracket, and cross-drilled holes that allow you to mount it almost any way you..." Read more

    "Great design, poor execution.I've had to resort to obscene amounts of teflon tape to get 3 of the holes to seal (one still seeps a bit)...." Read more

    "...The nuts do stick out on the rear but the machine work and finish is very nice...." Read more

    "LOOKS AND WORKS GREAT, ONLY DISAPPOINTMENT WAS BAG WAS TORN AND MISSING ONE BOLT, AND NUT THAT HOLD ON THE MOUNTING PLATE." Read more

    Customers are mixed about the quality of the auto part. Some mention it's very high quality, well built, and tough construction. However, others say that it was not threaded correctly, has poor quality on the thread tolerances, and the threads are way too small or tight.

    "...Pleasantly surprised at the noticeable heft, and build quality of this part. Threading on mine is deep, clean, and tight across all 6 ports...." Read more

    "Like other complaints this part was not threaded correctly. Could barely start a 1/4 npt fitting even after chasing and bottoming out a tap in it...." Read more

    Customers are mixed about the leakage of the auto part. Some mention that it's worth it and needed, while others say that it leaks badly, all ports leak, and one still seeps a bit. They've tried replacing fittings, pipe dope, etc.

    "...(one still seeps a bit). Tried replacing fitting, pipe dope, etc...." Read more

    "...shut off, quick connect fitting and outlet to the tank and holds air without leaks." Read more

    "...So far, so good. Put the air to it and it leaked terribly...." Read more

    "...No leaks and I've had it hold pressure for months." Read more

    10 customers mention5 positive5 negative

    Customers are mixed about the value of the auto part. Some mention it's a great bang for the buck, while others say that the holes are tapped too small and it'd be useless.

    "Good manifold for a good price...." Read more

    "...Totally useless." Read more

    "...great and love buying USA whenever possible, especially when its reasonably priced...." Read more

    "...This was a total waste of money...." Read more

    9 customers mention6 positive3 negative

    Customers are mixed about the mounting of the auto part. Some mention it works great, has multiple mounting options, and is affordable. The detachable mounting bracket is spot-on perfect, and can attach to the wall also. However, some customers say that they received a missing bracket screw and two nuts.

    "...Detachable Mounting bracket is spot-on perfect for my purposes in attaching this D-block firmly to the compressor cabinet...." Read more

    "...Plastic bag was open and missing 2 nuts...." Read more

    "This manifold is super well made, and it's unique -- it comes with a bracket, and cross-drilled holes that allow you to mount it almost any way you..." Read more

    "This is a very versatile manifold with many different mounting configurations...." Read more

    8 customers mention3 positive5 negative

    Customers are mixed about the ports of the auto part. Some mention that the front facing 14" outlet ports are spaced more than enough so you could run 4 beefy quick-fitting turbos, while others say that 5 of the six ports were tapped too deep and no way to seal the threads. Some customers also say that the 1/4" NPT ports are WAY out of spec and there is no back-port.

    "...only to find out that all the 1/4 NPT ports are WAY out of spec (tapped WAY too small) I tried over a dozen 1/4 NPT fittings from a verity of..." Read more

    "...The front facing 1\4" outlet ports are spaced more than enough so you could run 4 beefy quick-connect couplers in line with ease and without..." Read more

    "...this the perfect fit for my OBA system, not, 5 of the six ports were tapped too deep, no way to seal the threads, the last port, well, was drilled..." Read more

    "...installed it yet (will tomorrow) but it seems solid enough, all ports threaded properly, don't see anything that could be a potential problem...." Read more

    7 customers mention4 positive3 negative

    Customers are mixed about the size of the manifold. Some mention that it's well machined, compact, and just what they needed, while others say that the tap that makes the threads does not go, and that it could barely start a 1/4 npt fitting.

    "...Makes everything seem neat and compact instead of a mess of coupling and various adapters. Makes things much simpler...." Read more

    "...Due to the relatively small size of the manifold, the tap that makes the threads does not go deep enough to allow for normal male threads to go much..." Read more

    "...Overall, very happy with it. Very compact. Using it as a vacuum manifold to distribute vacuum on my vacuum table." Read more

    "...Could barely start a 1/4 npt fitting even after chasing and bottoming out a tap in it...." Read more

    works or doesn't work?
    I bought this to make my own ARB DIFF Breather (F&R Diffs + A/T and Transfer Case) = 4 ports or linesDue to the relatively small size of the manifold, the tap that makes the threads does not go deep enough to allow for normal male threads to go much more than 1/8 to 1/4 a turn.IF you tap them until the tap bottoms out, you may get 2 full turns before it gets tight.(I did)IF I cut 1/4 to 3/8 of an inch off of my good tap (not gonna happen), that would allow the tap to go a bit deeper (before bottoming out) and make the hole bigger so that more threads are engaged and the fitting is more inside the manifold.Depending on the male fitting, you may or may not have an issue.The "muffler" (wire mesh breather) fit by hand and fully seated.(Notice it has shorter threads)All other "normal" full size male fittings did not seat and only went in 2 turns after chasing the hole.Plastic bag was open and missing 2 nuts.Amazon Prime gonna send me another complete unit = just so I can get the nuts that were missing in the original shipment.
