SIMPSON 50ft 5/16in MorFlex Pressure Washer Hose — 3700 PSI, M22 Dual O-ring, Polyurethane Jacket

The Simpson 50ft MorFlex 5/16" pressure washer hose is a flexible, kink-resistant replacement or extension hose rated to 3700 PSI and usable with cold water up to 140°F.

Designed for homeowners and professionals who need a dependable, easy-to-handle hose for pressure washing tasks, this 50-foot MorFlex hose pairs a lightweight polyester braid with a durable polyurethane outer jacket. It arrives with M22 threaded fittings featuring a dual O-ring seal and includes a 14/15mm adapter so it integrates with most standard gas and electric pressure washers. The hose balances flexibility and abrasion resistance so you can reach distant areas without sacrificing durability.

How does this hose handle flexibility and kinking on the job?

MorFlex construction prioritizes pliability while resisting kinks, letting the hose move freely around corners, furniture, and equipment. The inner braid and flexible jacket reduce stiff spots that cause bends to pinch closed, keeping water flow consistent when pulled or coiled.

• MorFlex inner design for increased bend tolerance and reduced kinking.
• Lightweight polyester braid improves handling and maneuverability.
• 4-inch bend protectors at both ends reduce stress at the fittings.

Will it connect to my existing pressure washer and accessories?

The hose uses industry-standard M22 threaded fittings with a dual O-ring sealing system to provide reliable connections to most pressure washer spray guns and accessories. Simpson includes a 14/15mm threaded hose adapter so you can use it as either a direct replacement or as an extension to match existing hose sizes.

• M22 threaded fittings for broad compatibility with gas and electric units.
• Dual O-ring design improves leak resistance under high pressure.
• Includes 14/15mm adapter to match common garden hose-style fittings.

How durable is the outer jacket and will it withstand jobsite wear?

The outer jacket is made from non-marring polyurethane chosen for abrasion resistance and easy cleaning, so it handles rough surfaces without scuffing paint or decking. Combined with reinforced braid and protected fittings, the hose holds up to typical residential and light commercial use when used within specified limits.

• Polyurethane jacket resists abrasion and wipes clean quickly.
• Non-marring surface reduces scuffs on finished surfaces.
• 4-inch reinforcement at ends protects against premature wear at connection points.

What performance limits and warranty should I be aware of?
