The Simpson MorFlex 40224 is a 1/4-inch by 25-foot replacement and extension hose built for cold water pressure washers rated up to 3,300 PSI. Contractors, auto detailers, and homeowners reach for it when a cracked or worn factory hose is holding back a machine that still runs strong - the M22 threaded ends let it drop straight onto most gas and electric units without adapters.
Where it is used
The MorFlex jacket stays flexible in cool weather and resists the kinks that shorten hose life, which makes it a practical pick for:
- Replacing a leaking or burst OEM hose on a cold water pressure washer up to 3,300 PSI
- Adding 25 feet of reach with the included adapter so you can work farther from the machine
- Auto and fleet detailing where a non-marring jacket protects paint and trim
- Deck, siding, and driveway cleaning that calls for a kink-resistant hose you can drag across abrasive surfaces

Frequently asked questions
Will the 40224 fit my pressure washer?
It uses industry-standard M22 threaded connections with a dual o-ring seal, so it fits most gas and electric cold water pressure washers rated up to 3,300 PSI. Check that your machine and gun use M22 fittings before ordering.
Can I use this as an extension hose?
Yes. It works as a direct replacement for the original hose, or with the included adapter you can join it to your existing hose to add 25 feet of reach.
Is this hose rated for hot water?
No. The 40224 is a cold water hose rated for water temperatures up to 140 degrees F. Do not use it on hot water or steam machines.
What makes MorFlex different from a standard hose?
The MorFlex polyurethane jacket is engineered to stay flexible and kink resistant while resisting abrasion, and it is non-marring so it will not scuff finished surfaces as you drag it.
