SIMPSON MorFlex Pressure Washer Hose — 50 ft 5/16" 3700 PSI, M22 Dual O‑Ring, Abrasion‑Resistant

The SIMPSON 50ft, 5/16" MorFlex hose is a flexible, kink‑resistant replacement or extension hose rated to 3700 PSI for cold water pressure washing up to 140°F.

This MorFlex hose combines a lightweight polyester braid with a polyurethane outer jacket and threaded dual O‑ring fittings to deliver easy handling, broad compatibility, and abrasion resistance. It ships with a 14/15mm threaded adapter and fits most standard gas and electric pressure washers that use M22 style connections. Built to be non‑marring and deployable as either an original replacement or an extension, the hose includes 4‑inch bend protectors to reduce stress at each end.

How does this hose perform during everyday pressure washing?

The MorFlex construction prioritizes flexibility and kink resistance so you can move freely around vehicles, decks, and siding without frequent untwisting. Its lightweight braid makes dragging and coiling easier than heavier rubber hoses, while the polyurethane jacket resists scuffs and abrasion when pulled over rough surfaces.

• Flexible 5/16" inner profile for maneuverability
• Polyurethane outer jacket resists abrasion and wipes clean
• 4" bend protectors at each end reduce wear and extend service life
