Silicone Rubber Blue Coolant Hose, 2.14 Inch OD, 1.75 Inch ID, 36 Inch Long

For pressure washer applications, 400 PSI burst pressure gives you a reasonable safety margin in most standard setups. Keep in mind that burst pressure is the failure point, not the working pressure, so your actual operating pressure should stay well below that ceiling. The hose is listed specifically for pressure washer use, so it's built with that duty in mind. The 4-ply polyester-reinforced silicone construction adds to its ability to hold shape and resist wear under repeated pressurization cycles.

You are looking at a 1.75 inch inside diameter, 2.14 inch outside diameter, and a 36 inch overall length.

This hose is rated to handle a burst pressure of up to 400 PSI, so it should hold up well in demanding applications.
