Note: It is MOST IMPORTANT to ensure that Couplers used on Agchemicals are rinsed with clean water IMMEDIATELY after use. This will help avoid crystallization or dried solids from effecting the functionality of the Coupler and help prevent seal deterioration and increase longevity.

Couplers used in Agchem service should always be flushed using a Micromatic Rinsing Coupler shown on a following page.
