Simpson Morflex 3700 PSI Pressure Washer Hose, 25 ft - Flexible

In this review of the MorFlex 3700 PSI pressure washer hose the bottom line is simple: this is a practical, budget-friendly replacement or extension for most residential pressure washers that need a flexible, kink-resistant line. It is aimed at homeowners and light contractors who want an easy-to-handle hose that connects with standard fittings and tolerates cold water up to warm temps. The biggest reason to buy is the combination of flexibility and compatibility: the MorFlex construction makes it noticeably easier to manage than many stock hoses while fitting virtually any unit with M22 threaded connections.

Key Features

• Cold water compatible: Built for water temperatures up to 140F, making it suitable for most residential cleaning jobs without heat-sensitive limits.
• Standard connections: Includes M22 threaded hose connections and a 14/15mm adapter so it connects easily to common gas and electric pressure washers.
• High pressure rating: Rated for use with pressure washers up to 3700 PSI, covering the needs of typical home and many light commercial units.
• MorFlex construction: Lightweight polyester braid and a polyurethane outer jacket provide strong flexibility and resistance to kinking for easier handling.
• Durability details: 4-in bend protectors at each end plus an abrasion-resistant outer jacket that wipes clean for longer service life.
• Versatile use: Works with spray guns, foam guns and other accessories so it can serve as a replacement hose or an extension to an existing setup.

Who It's For

This hose is a good match for homeowners, car enthusiasts, and small contractors who need a reliable replacement hose or a simple extension for cleaning patios, decks, siding, vehicles and similar surfaces. Its M22 threaded connections and included adapter make it broadly compatible with many common pressure washer models.

Those who should look elsewhere include heavy commercial users who require extremely high-duty industrial hoses or anyone who needs hot water use above 140F, since this hose is rated for cold to warm service only. Also, users seeking an ultra-long warranty or professional-grade abrasion resistance may prefer a heavier-duty option.
