Bought these to replace my vacuum lines on my 1995 F250. I’m very particular about what I put in my truck and these hoses meet my high standards! They are flexible and easy enough to manipulate around the engine compartment but they have a thick wall and fit perfectly on the vacuum nipples! Nice snug fit and no need for clamps! I bought 5/32 and 7/32 and hose in different colors to be able to identify my hose! Honestly the products this company sells are high quality and magnificent! Buy with confidence and replace these vacuum lines for good! On a side note, I bought sheaf to slide over these hoses but I do not really need it as these are high temperature hoses! Perfect product, fast shipping arriving in just two days from ordering, and great follow up customer service to check to be sure I was satisfied!! A++ all around!!
Great price and shipping ! Exactly what I needed call Quality is great just as good if not better then some big name brands that I’ve use in the pass !! Definitely my new got to spot for vacuum lines !!
I have used these products multiple times and have never been disappointed. Their pricing is great and the product is really high quality.
I bought this tubing to repair my favorite Box Kite. 5 3" sections of thinner 4mm ID tubing had held the struts in place while it was airborne since it was new. After years the thinner tubing wore out. Your thicker tubing seems to be just right. I'll let you know in a few more years! Ed Ogletree
This product was the quality I wanted for a very reasonable price.
Bought this to change the old tubing on my 02 Jetta TDI. It worked very well in replacing some of the larger bore vacuum tubing.
