MrPEX® 1 1/2” BRASS MANIFOLD FOR 5/8” AND 3/4” PEX AND PEX-AL-PEX TUBING, 2-12 LOOPS
MrPEX 1 ½" Brass Manifold is made from high quality alloy extruded and chrome plated aer ma-
chining, and is oered in 2 through 12 loop conguraons. The manifold comes mounted on brack-
ets and it is equipped with high ow ball valves provided with thermometers, manual air vents and
ll/drain valves. The SUPPLY (upper) manifold is ed with balancing owmeters with readable
range of 0 to 2 GPM that allow ow adjustment of each individual loop. The ow meters have a brass
body and the sight glass is made from temperature and impact resistant plasc material, all compo-
nents are an-freeze resistant up to a 50% mix. The RETURN (lower) manifold, has manual on/o
valves that controls the ow for each individual circuit. The manual knob can be removed to accom-
modate the MrPEX actuators (part# 5120700 & 5120701). Supply and return mains can be connected from either le or right
sides. The manifold comes ready for a le-hand connecon. Connecon from the right can be done by removing the manifold body
from the brackets and ipping them over.
