Continental 20455567 Pressure Washer Hose

This Continental 20455567 hose is built for pressure-washing tasks that demand a 3/8 in inside diameter and a 25 ft reach. The nitrile tube and neoprene cover handle water and common cleaning chemicals in residential or light-commercial settings. Carbon-steel braid reinforcement and carbon-steel MNPT fittings provide a 4:1 safety factor for reliable connections.

Thermals noise and power draw

The hose operates from -20 °F to 250 °F and is rated for a maximum working pressure of 4,500 psi at 70 °F with a burst pressure of 18,000 psi. A 3 3/4 in bend radius allows tight routing without kinking, while the 0.6875 in outside diameter keeps the assembly compact. No external power or moving parts are involved, so noise and power draw are not applicable.

Upgrades and replacements

This hose replaces worn or lower-rated 3/8 in assemblies that cannot meet a 4,500 psi working pressure or the -20 °F to 250 °F temperature range. The jump is worth it when the existing hose shows cover cracking, fitting corrosion, or burst-pressure margins below the 4:1 safety factor. It is not suited for applications requiring a different inside diameter, longer length, or non-MNPT fitting types.

Questions about this item

How do I connect the MNPT fitting on this Continental 20455567 hose to my pressure washer pump?

Thread the carbon-steel MNPT end directly into the pump's female NPT port, using thread sealant if the manufacturer recommends it, and tighten with a wrench on the fitting hex — do not twist the hose body.

When should I replace this 3/8-inch nitrile/neoprene hose?

Replace it if the cover shows cracks, abrasion exposing the carbon-steel braid, leaks at the crimped fittings, or if the hose becomes permanently kinked beyond the 3 3/4-inch bend radius.

What is the first limit I will hit if I run this hose continuously at 4,500 psi?

The 250 °F temperature ceiling is the first hard limit; sustained operation above it degrades the nitrile tube and neoprene cover even though the 4:1 safety factor handles the pressure.
