Buyer’s checklist

What separates a good pressure washer accessory from a poor choice?

The right accessory must match your machine, your connections and the cleaning task—not simply have the highest advertised rating.

01

Correct connections

Identify the connection on the washer and spray gun separately. M22 connector dimensions and quick-connect types are not interchangeable by appearance alone.

Check:Connector type, size, gender, and adapter requirements.
02

Suitable working-pressure rating

Choose a hose rated for the equipment’s required operating conditions. A PSI match does not establish physical compatibility.

Check:Manufacturer rating and machine documentation.
03

Practical length and diameter

Extra length adds reach but also hose to manage. Diameter and length affect flow losses under specific operating conditions.

Check:Reach, hose bore, machine flow, and connection sizes.
04

Construction and temperature

Material, abrasion resistance, bend behavior and water-temperature limits matter for durability and handling.

Check:Jacket material, approved temperature and use conditions.

Before ordering any accessory, verify the machine model, connection requirements, operating ratings and intended use against manufacturer documentation.
