Inlet Hose comes in either 6.5,12, or 20 ft sizes.
There seems to be a common theme when it comes to the parts and pieces that make up the car washing products that I use. They tend be obscure, they aren't cheap, and they all possess an insane amount of quality.
This should be a very simple thing. You need a hose to feed your pressure washer/deionizer. But I don't want leaks or to have crappy fittings connected to my quality Prier Hose Bib.
This short inlet hose is the best there is. This is the 5/8" Diameter version. You'll only need to buy this once, and it will last a very, very long time.
The purchasing options for this product:
Buy just the hose by itself in 6.5', 12', or 20'
