1/2" PEX adapters are included by default. For other size adapters (free upgrade - 3/8" PEX, 5/8" PEX or 1/2" PEX-AL-PEX) make a note at checkout.

11-branch, Premium Radiant Heat Manifold Set with 1/2" PEX adapters (Supply and Return pair).
Pre-assembled, pressure tested and comes with everything shown in the picture, including 1/2" PEX manifold adapters.

SSM111 set is typical for radiant floor heating applications in areas with a total of 2250 - 2500 sq. ft of space, when used together with 1/2" PEX tubing (installed 9 - 12" on centers).

Complete list of components:
(1) Supply side radiant heat manifold with (11) flow meters and (11) PEX tubing outlets - lower manifold w/ red shut-off valve.
Flow meters allow to monitor the flow of water in GPM (Gallons Per Minute) through every manifold's branch.

(1) Return side radiant heat manifold with (11) manual balancing valves and (11) PEX tubing outlets - upper manifold w/ blue shut-off valve.
Manual balancing valves allow to balance the radiant heating system and are used to regulate the flow of water through manifold's branches.

(2) 1" NPT isolation shut-off ball valves with 1/4-turn color coded handles and built-in replaceable thermometers (both F/C readings displayed).
Allow to service the system and monitor supply (incoming) and return (outgoing) water temperatures.

(1) Automatic air vent to eliminate air from the system.
Air vent are used to eliminate the air from the radiant heating system, prevent air traps and enhance overall performance.

(2) Drain/fill valves with 3/4" garden/drain hose connection and a cap.
Used to purge/fill the radiant heating system.

(2) Manifold mounting brackets with bolts.
Superior bracket design offsets the radiant heat manifolds from the wall and allows for easy access and fast installation.

(22) Compression-style adapters for 1/2" PEX tubing.

Other suggested components:
To pressure test the radiant heat manifolds, use a Pressure Testing Kit (SKU# TESTKIT).
