Caleffi 6686D5S1A TwistFlow Radiant Manifold Assembly 4 Loops, 1" Brass with Temperature Gauges

The Caleffi 6686D5S1A TwistFlow is a 4-loop brass radiant manifold assembly with a 1" supply size and temperature gauges.

It distributes supply water to and collects return water from radiant floor, wall or snowmelt loops, and the gauges make it easy to check temperatures during setup and service. The assembly is 17" long, rated to 150 psi and 180°F, and can be used with water or glycol mixtures up to 50%.

Before ordering, confirm the number of loops (4) and the 1" trunk connection, and check the loop outlet size and tubing adapters required for your PEX in the technical data sheet. Actuators for zoning are sold separately.
