UPGR8Universal 4mm/6mm/8mm/12mm Inner Diameter High Performance Silicone Vacuum Hose Kit (Blue)

Excellent upgrade and repair for my 1988 Toyota Pickup. The hoses are a large diameter, larger than what you'll remove as stock from an engine, but room shouldn't be a problem unless you feel millimeters will matter if routed through an intake manifold or something similar such as a very narrow channel. I thought I could get away from using clamps of some kind and have found that some vacuum ports were tight with just dried dish-soap only, but others were not and needed some kind of clamp after all, especially the larger diameter hoses (which I found my vehicle using clamps for those particular connections regardless, and I successfully reused that hardware as you should if you can.) That's not the biggest deal, and shouldn't be. These hoses easily answer a question to what can be a very generic problem when it comes to older vehicles driven mostly by vacuum, and are well worth it. The color is a bright blue, which wasn't a concern to me as much as the price, which I thought very fair for all the sized you get.

Great hoses. Sturdy and they look great. All the sizes and lengths I needed for my 1989 chevy k1500 (350 v8/ 5.7 L)

Easy to use and very durable, looks great too

Not the best pic to show hose, but you can see the blue lines. Used them strictly as vacuum hose. Working great so far, installed almost 4 months ago. They’re a little difficult to slip on, but once they’re on they won’t be slipping off. Easy to cut. Over all I liked the hose, had a lot left over.

Plenty of lines to fit different size vacuum lines

Wow! Superior quality silicon hoses. The tubing variety and lengths where as expected. If you are doing silicon vacuum lines, then these are materials to use. Great value for the money. Thank you. NOTE: for vacuum lines only. Not for use as gasoline or coolant hoses.UPDATE: just an update for those doing vacuum lines. The 12mm tubing has a smaller relative wall thickness than the other hoses (actually its the same). Still good, but the largest tubing in the set (the 12 mm ID) will collapse on larger vacuum situations. I used the larger 12mm ID tubing on my main engine manifold vacuum port and brake booster (both straight short lengths of about 6-8 inches each) and found that the one hose collapses during vacuum increases of 18- 20 in/hg which is not good. Then it pops back to normal when the vacuum is removed which would make for a troubleshooting nightmare. I changed these two hoses back to reinforced rubber hoses (like heater hose). This tubing kit is STILL GREAT, but I would suggest avoiding use of the 12mm tube on your main vacuum. All the other tubes (4mm, 6mm, 8mm) work perfectly with no collapse under vacuum whatsoever. Hope this helps

the big hoses collapse but the small hoses work fine

I will get straight to the point.These hoses are purely AMAZING. The durabilty and construction of this material is a solid 11/10. On top of that, they have a HIGH heat resistance; similar to that of stock motorcyle and car engine tubes and hoses. I've installed alll four different sizes on my vehicle as you can see in the photos I've attached. On top of all this...they are LONG. You will have to be either a HORRIBLE cutter or complete idiot to waste all of this that comes with your purhase. The photos are two months old, as I have replaces ALL the stock hoses in my cars engine bay with these and I STILL have a rediculous amount left over! Crazy!There are no cons about these hose whatsoever. They are a sleek, matte red, EASY to clean any dirt/gunk off with a simple swipe of water and a towel, and they hold up to the tightest tubing connections, with good flow of whatever liquid ( or air..) is flowing through them.I would 115% recommend anyone to purchase these as I would purchase again.

The product is as advertised and has preformed well. And it arrived on time.

The length of hose is in cm not feet....

Hoses wont stay on contactorsNot happy
