  1. Direct Performance Solutions (verified owner)

    We were tired of fighting push lock fittings that would leak. Decided to buy this tool and it’s $250 well spent.

  2. Scott Yaskus

    This is a well built tool that works. A timesaver.

  3. Russell @ Nerd Rods

    This tool is AMAZING!!!! We use the push locks on everything here at Nerd Rods from out custom fuel systems, to power steering return lines (not the pressure power steering line obviously) and oil cooling systems on the transmission and engines. Heck we probably use 12-30 ends on each chassis leaving our shop and at 14-20 chassis a year that A LOT of end.

    I did the first car with the push lock ends and hand bruises on the insides of my palms after two days of fighting with them to get them all seated. Got this tool and did a whole car in a matter of hours. It paid for itself on the first car in time alone. Here we are 20-30 chassis projects later and well over 300 ends, probably closer to 400 and we’ve finally worn out the little plastic jaws (just call, they have replacements if you use it that much) killer tool everyone should own, hands down!

    Wow, just WOW!
    In a world full of disappointments, this bad-arsed tool does satisfy. Built like a tank, will last my lifetime, and makes a painful and difficult chore a breeze.
    Pays for itself in one morning of quick and easy hose assembly. Grips so nicely that it will seat hose already covered in woven fiberglass firesleeve. Too koul.

    Bought this tool a year ago and use it quite often. What a time saver.
    Thumbs up. My boss bought this for the company at PRI and what a joy to use.

    Amazing tools! It’s a shame though that they’re cased in cheap blow molded cases that have those horrible wear and break hinges and locks. A few more pennies for slide together hinges and 2 piece locks. Beats the heck out of holding it together with duct tape later down the line!

      Hello Mike,

      Sorry about your case hinge breaking. We have had a few cases fail out of
      3000. It is still our responsibility to take care of our customers.
      I have a s/s hinge repair kit I will send to you to get your case back in shape.
      If you will send me your address, I will get it off to you in the mail.

    One of the best tools I have purchased in awhile. Great tool

  8. Michael Ballard

    Much more durable and solidly constructed than I expected. We had over 150 1/2″ Swagelok Push Lock fittings to install, and this tool handled them without a problem. I can turn the bolt by hand to fully install a 1/2″ Push Lock fitting with this, but it’s much quicker with a wrench or a drill. I’ve since used it for about a dozen 3/8″ air lines as well. I never noticed any damage to any of the hoses from this, either.

    Fantastic tool, even in our industrial setting I expect this to last many years.

    Wow, this tool is amazing.

    I install and crimp hundreds of barbed hose fittings during the course of a year. I have been using a Dixon 270AT which required my holding the hose and re-positioning it a few times while the barbed fitting was being pushed into the hose to insure it would go in straight. The Dixon 270AT holding cam would also chew up the exterior of the hose. The Dixon 270AT = A lot of effort

    I just bought the Koul Tool EZ ON Hose Press 409B and it arrived a few days ago. I just tried it for the first time yesterday morning (2019-05-03). Sayin g it is amazing is an understatement as to how well this tool works. It held onto the hose firmly without marring or chewing it up and then pushed the hose onto the barbed fitting very easily.

    This tool performs exactly as the inventor intended…..FLAWLESSLY. Very well thought out design, small footprint, well built, and best of all, it’s price is very reasonable.
    The Koul Tool 409B = Very little if any effort

    The question now is what to do with the Dixon dinosaur?
