What to know about this hose

The SIMPSON MorFlex 40224 is listed as a 25-foot hose with a 1/4 in inside diameter and a maximum pressure rating of 3,300 PSI. The points below explain the buying decisions these published specifications raise; they are not a claim of fitment with any particular pressure washer.

Plan your working reach

At 25 ft, this is the shorter-reach option in our current catalog. Consider how far you need to move from the washer, and whether a longer hose would reduce the need to reposition the machine. A shorter hose does not guarantee better cleaning performance.

Check hose diameter

This model uses a 1/4 in inside diameter. Do not assume it is interchangeable with a 5/16 in or 3/8 in hose solely because the end fittings look similar. Confirm your washer manufacturer’s hose requirements.

Verify both end connections

The listing identifies an M22-threaded connection family. M22 threads can have different internal insert dimensions and seals; verify the precise connector configuration at both ends and whether your washer needs an adapter. An M22 label alone is not a fit guarantee.

Respect water and temperature limits

This listing identifies cold-water use and gives a maximum temperature of 140°F (manufacturer MorFlex specification). Do not use it for hot-water operation without explicit manufacturer approval.

Compare a meaningful alternative

Compare the 40225 if you need a 25 ft option with a 5/16 in diameter and a different listed pressure rating; check connection dimensions independently.

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.
