SIMPSON MorFlex 3700 PSI Pressure Washer Hose – 25 ft, 5/16-inch ID, Cold Water

Overview

The SIMPSON MorFlex hose delivers flexible, kink resistant performance for cold water cleaning. Built with MorFlex technology, the hose stays supple under pressure, making it easier to maneuver around decks, patios, vehicles, and siding. The lightweight polyester braid reduces fatigue during longer sessions, while a polyurethane outer jacket remains non marring on delicate surfaces.

Design and materials

MorFlex emphasizes durability without bulk. The 4 inch bend protectors at each end help resist kinks at common turning points, and the jacket wipes clean quickly after use. The outer layer is abrasion resistant for long life, even in busy work zones.

Compatibility and connections

The hose uses standard M22 threaded connections and is rated for up to 3700 PSI, enabling compatibility with many home and light commercial machines. It includes a 14/15 mm threaded connector and a dual o ring design that fits both 14 mm and 15 mm fittings on compatible washers. With the included adapter, you can use it as an extension to your existing hose.
