Specifications & product details

REGIONS SUPPLY BUYING GUIDE

Product details & buying advice

Check both sides of an adapter or transfer fitting before ordering, especially when joining different connection systems.

Product type	ACME, POL and transfer fittings
Part / SKU	3171

What to check before ordering

Identify ACME, POL or NPT, the size and male/female form at each end, and the required sealing arrangement.
Confirm the service medium and material, including the specified replacement seal if one is needed.
Have qualified gas-service personnel check the completed connection.

Service reminder: Verify what a cap or plug is designed to do. A protective dust cover should not be assumed to provide a pressure-retaining shutoff.

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.
