The 25-foot, 5/16-inch MorFlex offers a different reach from the other MorFlex lengths. Choose length based on your work area; verify your machine’s pressure, the exact M22 fitting insert dimensions and any adapter required. Do not assume every M22 hose fits every M22 washer.

What to know about the SIMPSON 40225

This 25-foot MorFlex is a 5/16-inch cold-water hose rated to 3,700 PSI. It is a short-reach choice in the MorFlex 5/16-inch range, not a universal replacement for every pressure washer.

When the 25-foot option makes sense

Consider this length when the pressure washer can stay close to the cleaning area. If you regularly need to move the machine to reach farther sections, compare the 50-foot 40226 before buying. Longer reach may be more convenient but adds hose to handle and store.

Do not confuse 40225 with 40224

Both are 25-foot MorFlex hoses, but 40225 has a 5/16-inch inside diameter and a 3,700 PSI rating; the 40224 is listed as 1/4-inch and 3,300 PSI. These are distinct products, not interchangeable variants by default.

Online and in-store model numbers differ

SIMPSON identifies 40225 as the in-store model and 41108 as its online model. Check the model and dimensions on the actual seller listing before ordering.

Connector fit is the critical check

SIMPSON specifies M22 threaded connections, but M22 insert dimensions and seals vary. Match both hose ends against the washer and spray-gun specifications; do not rely on the M22 thread name alone.

Cold-water operation only

The manufacturer's MorFlex specification limits water temperature to 140°F. Do not use this hose with hot-water equipment unless the manufacturer explicitly approves that application.

What to check before buying

Compatibility is not confirmed for your machine. Match the pressure rating, operating temperature, hose fitting type, fitting insert/seal dimensions, and the manufacturer’s washer-specific guidance. Do not infer fitment from thread name alone.
