Series 668S1 TwistFlow pre-assembled distribution manifold for radiant panel systems with built-in sight flow gauge/balancing valve

Note: This manifold requires 12 Loop Fitting Assemblies (please see below).

Distribution manifolds for radiant panel systems are used to optimally distribute the heating fluid in floor heating system circuits and ultimately improve the control of heat emission from the panels. The manifolds ensure that the flow to each circuit is regulated precisely and also control the shut-off, venting and automatic removal of air from the system.
  • 1" NPT inlet ball valves
  • Maximum working pressure: 150 psi (10.3 bar)
  • Maximum temperature: 180°F (82°C)
  • Maximum peak temperature: 200°F (93°C)
  • Loop Cv: 1.23 (combined supply & return ports)
  • Outlet center distance: 2 inches

This manifold requires (12) Loop Fitting Assemblies:

PEX Loop Fitting Assemblies Options
PEX-AL-PEX Loop Fitting Assemblies Options
Optional Installation Accessories:

Loop End Cap
Actuators
If you want to use your manifold to heat multiple zones, you can purchase return side actuators that work along side thermostats. The actuators act as zone valves to allow you to use one manifold to control the temperature in different rooms independently.

fittings leak

I bought this manifold and 1" NPT by 1" pex fittings. I started to fill the system and the fittings leak where screwed into the manifold. Not sure if it's the fittings or the manifold however it's a disappointment and a lot of time and money spent. Yes the fittings are tight and have pipe dope on them.
