I would assume that there is a safety factor in the rating. A 4000psi hose should safely hold 4000psi.

Why does the product say it has a one month warranty but when I scroll down on the page and click on terms and conditions, it says there is no warranty. Is there a warranty or not?

How can I reduce the corrosion on the quick disconnects? Whenever we have to changeout a busted gun, the quick disconnects are corroded and invariably leak. Any suggestions?
1 answer-
NorthstarExpert12· a year ago
The fittings of this hose are zinc plated steel. If the plating gets scratched or nicked, the steel becomes vulnerable to corrosion. Regularly clean the parts to remove any dirt, debris or corrosive substances to extend the life of the fittings and the zinc plating.

Does the NorthStar Pressure Washer Hose 4000 PSI 25 ft Model #989401979 attach to a outdoor water faucet? New at this!! Thank you!
1 answer-
NorthstarExpert7· 2 years ago
This is a pressure washer hose that would connect between the pressure washer pump outlet and the sprayer gun. A garden hose would connect from your water faucet to the pump's inlet.

What the temperature range of this hose - particularly on the lower-end? I assume that bc it is rubber, that it will remain more flexible than poly hoses when in cooler temps. And is this a true 3/8" hose?

This hose has an operating temperature range of -40 degrees F to 250 degrees F. The inside diameter of the hose is 3/8", the outside diameter of the hose is 14.7mm - 16 mm.
