Product Description

REGIONS SUPPLY BUYING GUIDE

Product details & buying advice

When replacing a filling connection, compare the container side, hose coupling and check-valve arrangement as one assembly.

Product type	Filler and back-check valves
Part / SKU	6579

What to check before ordering

Verify the medium, container thread and ACME size for the exact filler-valve model.
Identify any shutoff or overfill-prevention function from the model specification rather than its appearance.
Use trained filling and service personnel following the manufacturer’s procedure.

Service reminder: A double-check filling valve does not, on its own, confirm the presence of an overfill-prevention device.

Have gas-system installation and service completed by qualified personnel. Use the current instructions for the exact model and the requirements that apply at the installation location.
