Xylem-Bell & Gossett Tank Fitting

Xylem-Bell & Gossett Airtrol tank fittings are made for hydronic heating systems that use plain steel compression (expansion) tanks. They help set the correct initial liquid level in the tank. They also provide positive air control, so the tank can absorb system water expansion and keep pressure stable as operating conditions change.

Key Features:

• Helps establish the proper initial water level in the compression tank
• Provides positive air control for the hydronic system
• Supports proper system pressurization as water expands and contracts
• Designed for use with Bell & Gossett plain steel compression tanks
• Built by Bell & Gossett, a Xylem brand with a long history in hydronic heating and cooling products

Pick the fitting that matches your tank and system in the individual product listings. Bell & Gossett pre-charged bladder and diaphragm ASME tanks do not need an Airtrol tank fitting, so this product line is intended for compression tank installations.
