Heatlink 75210 Stainless Manifold 10 Loop 1-1/4 Inch

Product Description

The HEATLINK 75210 is a high-flow stainless steel radiant heating manifold configured for 10 loops with a 1-1/4 inch main line connection. It serves as the central distribution point in a hydronic radiant floor heating system, dividing supply water across multiple zones and collecting return flow from each loop. Stainless steel construction resists corrosion and handles the continuous wet conditions common in closed-loop hydronic systems. This manifold is installed by licensed plumbers and hydronic heating contractors working on residential and light commercial radiant systems.

The 75210 is suited for slab-on-grade, below-subfloor, and staple-up radiant installations where 10 individual tubing loops must be served from a single supply and return manifold station. Its high-flow design reduces pressure drop across the manifold body, making it a practical choice for larger zone counts where balanced flow distribution is critical. Manufactured in the USA, it is appropriate for new construction and retrofit hydronic projects requiring a reliable, corrosion-resistant manifold assembly.

Key Features

• 10-loop configuration supports up to 10 independent radiant heating zones from a single manifold station
• 1-1/4 inch main line size accommodates higher flow rates with reduced pressure loss
• Stainless steel construction provides long-term corrosion resistance in closed hydronic systems
• High-flow manifold body design supports balanced distribution across all active loops
• Made in the USA

Compatibility

Designed as an OEM-style replacement or new-installation manifold for residential and light commercial closed-loop hydronic radiant floor heating systems requiring a 10-loop, 1-1/4 inch stainless steel manifold assembly.

Installation Notes

Installation should be performed by a licensed plumber or qualified hydronic heating contractor. Shut off the system boiler or heat source and depressurize the hydronic loop before removing or connecting manifold components. Follow local plumbing codes and IFGC guidelines for hydronic system installation, including proper support, expansion allowances, and pressure testing after assembly. Do not overtighten port fittings on stainless manifold bodies, as thread damage can cause leaks under system pressure.
