Selecting the correct size hose connector to is critical .

Selecting the correct diameter hose to meet your length requirements is critical to maximize spraying pressure. The larger the hose diameter, the greater the pressure at the gun. As you go down in hose diameter size or increase the hose length, there will be less pressure at the gun, possibly affecting spray patterns.

When coupling hoses together, connect the larger diameter hose to the sprayer and smaller diameter

hose to the gun inlet for maximum pressure when spraying. Use a whip hose to allow for flexibility
