SaFTFlo® Cap Adapters - The Key

The SaFTFlo® Cap Adapter is a critical component to the closed-loop system, as it serves as the key to ‘unlock’ the chemical from the container when needed for dispensing.

To dispense chemical, the end-user removes the ship cap and attaches the cap adapter onto the neck of the container fitted with a bottle insert.

When the cap adapter or ‘key’ is connected, an umbrella valve opens the spring-loaded valve in the insert to ‘unlock’ the chemical from the container, taking it directly into the dispenser preventing contact with any handlers.

When the cap adapter is removed from the container, the valve closes automatically to lock the chemical in the container, to help prevent leaks or spills.

The SaFTFlo® cap adapter is available in an extensive range of sizes, two flow rates, and numerous material options to accommodate a wide range of chemicals.
