What to know about the SIMPSON 40226

The 40226 offers 50 feet of reach while retaining the MorFlex 5/16-inch inside diameter and 3,700 PSI pressure rating. The longer hose is the main distinction from the 40225, not a higher pressure rating.

Choose reach before assuming an upgrade

A 50-foot hose can help keep the pressure washer in one position when cleaning a larger area. Measure your route around vehicles, steps or corners; additional hose length also means more material to coil and store after use.

Pressure and diameter do not increase

The 40226 shares the 40225's published 5/16-inch inside diameter and 3,700 PSI maximum rating. Do not choose it expecting a higher-pressure hose merely because it is longer.

Check the online listing's alternate number

SIMPSON identifies the online model as 41109 and the in-store model as 40226. Verify that a retailer's listing corresponds to the 50-foot variant; do not confuse it with 25-foot model 40225 or 40-foot model 80392.

Fitment still needs a dimensional check

M22 threaded connections are specified, but the washer's connection insert and sealing arrangement must match. Confirm the exact fitting at both ends before purchasing an extension or replacement.

Stay within cold-water limits

The manufacturer's MorFlex specification lists a maximum of 140°F. A longer hose does not make this a hot-water accessory.

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.
