Easy to install to your existing shower head. It has made such a difference in giving our dogs a bath. So much easier.
I like that everything came in one package and included the pin wheel bearings as well as the thick washers which can be hard to find. I did notice after ordering though that it can be cheaper to buy the items individually.
Honest ad worked for my needs
Exact fit
As described
I use these as replacement o-rings on the top posts of my ball lock liquid and gas posts. The silicone makes it much easier to put on and take off the ball lock connectors, when the kegs are cold. Also seals great! A no brainer!
Good kit, haven’t used all the seals yet but the ones I have fit perfectly.
Don't be afraid to re seal on of these yourself, nothing to it. Worked great with no problems.
Perfect fit and saving money by doing it myself. The pool company charged me $150+ every time my pump's seals wore out and started leaking. The breakdown was $44 for the Go Kit and $100-$115 in labor. I watched a Youtube video on how to replace the Go Kit on my pump and now I am taking my wife to dinner with the savings!!
I use it to give our 100# dog a bath. I like that there is a push lever for on/off. Also I can keep it hung up and use it to rinse the tub after my bath.
worked on my supper pump
good it
worked fine !
Perfect parts kit. Helped me repair my pool pump and save a LOT of money. A+
Aight!!
Fit perfectly!
It was everything I needed for pump replacement
easy to use
Bit expensive, but they are what you need for keg posts.
Saved by bacon already - lost an o ring on the gauge hose and this kit had one to fit.
Great little rebuild kit. I do wish it came with new springs.
perfect repair parts for my minn kota motor
everything fit perfectly
Perfect! Everything fit perfectly. It's like I have new pump. Excellent ship time!
Well made product and helps to keep the smell of liquids in. I use it as a wast container to clean My Spray Guns.. will buy again!
I'm a BMW Technician and I always recommend this kit. It is a well thought out group of parts that will make your Vanos rebuild a breeze! The quality meets my standards, and the price beats them!
Comes in handy - never know what random o-ring you are going to need. Probably have a near life time supply of them with this kit.
All in one kit. Nice good price
Works great.
Replaced O rings in my BM and no more air leaks - worked just fine.
I finally got around to installing this over the weekend. The kit contains everything you could possibly need to get your VANOS running like new again. I didn't have the "rattle" that others did, but did have some vibration when idling that has significantly improved since install! A couple tips about install: Replace your valve cover gasket at the same time. You've already done the hard work and it's cheap. You MUST have a solid vice and impact wrench to open the VANOS and install the anti-rattle rings. I used a friend's garage specifically because of this. Get a bunch of dishes/cups to organize your bolts because you'll have a ton of them by the time you get here. A drill to install/remove bolts will save you a lot of time and effort. Torque the valve cover gasket bolts properly or you'll regret it. This took me ~6 hrs total as I ran into some difficult to remove bolts and one very stubborn solenoid connection.
Arrived quickly even though not on prime- didn’t have to install gamma ring - so that was a plus - they should just make sure they are installed - so people don’t have to do extra step- good quality bucket - will by again.
Good quality. No more leaks in my Mercruiser out drive.
awesome product, wont use anything else
excellent! everything right on
Perfect kit for your save a dive bag.
great pressure and handy handle the hose is very long and flexible this all chrome secondary showerhead is really a great product it was very easy to install and looks very good with my shower head attached. there is a "lever that allows you to redirect the water from a total stop to the original shower head and to the dog shower. totally in love with this product
Very easy to install. There is a lot of power for the sprayer. I have to turn the water pressure down a bit as it seems strong for my one dog with short hair. My huskie/lab's coat needs the higher pressure. Very pleased with the product.
Great kit. Every seal needed
the product matches the description. I have not used it yet
I made this into a chicken feeder, works great!
RECOMENDADO
Exactly as described, fitted perfectly and solved the leak
Excellent buy Thanks
product as described
The items purchased were an exact fit and my needs were satisfied. Very good product and my maintenance problem has been resolved.
Allright book. I'm an engineer in the biz, and bought this as a reference. Pretty much, it's a good overview. Just when it starts getting rolling... they move on to another subject. Unfortunate. Nevertheless, it's allright, and you can just search on google to pick up where they leave off (some of the time). Note, they clause everything, with do your own testing. While this is true, it gets old reading that five to ten times a chapter. The elastomer section was basic, but allright. The sealing types was basic, but allright. I was hoping for more, the penultimate specialized book. I guess I have to keep looking. It's allright.
Not sure what you can say about a direct fit o-ring but fit and worked perfectly! Good price as well!
We have a copy of this book at work. It is a good book for quick references. However, if you are dealing with special applications (i.e. toxic gases or lubricants, etc) you have go to the individual seal supplier for additional technical specifications. My recommendation would to use: 1) the seal manufacturer 2) engineering forums, such as eng-tips.com 3) ask a specialised engineering company, such as WES Engineering: [...]
