Simpson Morflex 3700 PSI Pressure Washer Hose, 50 ft - Flexible

In this review the Simpson MorFlex 3700 PSI pressure washer hose is examined as a practical replacement or extension hose for homeowners and light commercial users who need a flexible, durable line for regular cleaning tasks. The single biggest reason to buy is its combination of flexibility and temperature tolerance up to 140F, which makes it useful for washing patios, vehicles, siding and other common outdoor surfaces while remaining easy to handle and connect to most pressure washers.

Key Features

• Cold water compatible: Rated for use with water temperatures up to 140F, the hose handles most residential and light commercial cleaning chores without softening or failing.
• High pressure rating: Built to work with pressure washers up to 3700 PSI, so it will pair with a wide range of gas and electric units for effective cleaning power.
• Standard M22 connections: Comes with industry standard threaded M22 fittings and a 14/15mm adapter, making attachment to spray guns and machines straightforward.
• MorFlex construction: The lightweight polyester braid core delivers noticeable kink resistance and easy handling compared with heavier braided hoses.
• Durable outer jacket: Polyurethane outer layer resists abrasion and won't mar surfaces, while 4 in bend protectors at each end reduce stress where fittings meet hose.

Who It's For

The MorFlex hose is best for homeowners, small business operators, and anyone who needs an affordable replacement or extension hose that is easy to coil, connect, and store. Its 50 ft length and 5/16 in inner diameter suit common tasks such as car washing, deck and patio cleaning, and siding maintenance with medium to high-pressure washers.

Users who need industrial-grade longevity under continuous heavy professional use or who require unusually high temperature tolerance should consider higher-spec commercial hoses, as customer feedback includes mixed reports on long-term durability under very heavy wear.

Pros & Cons

Pros

• Good flexibility and kink resistance makes handling and storage easier than bulkier hoses.
• Works with most pressure washers because of standard M22 threaded fittings and included 14/15mm adapter.
• Non-marring polyurethane jacket and bend protectors help protect both the hose and surfaces during use.

Cons

• Durability is mixed in customer reports, with some users experiencing failure sooner than expected under heavy use.
