Faster, Cleaner Installations.
Faster, Easier System Service.
Our Hydronic Packages take the
guesswork out of compliance with
boiler manufacturers’ recommenda-
tions for near-boiler piping detail.
They are innovative in a way that
heating professionals appreciate,
combining components in convenient
packages that are easy to install, use
and maintain.
Following manufacturers’ recom-
mendations for proper near-boiler
piping is critically important. Proper
piping means safer installations for
customers. It means faster, easier
system service once the installation is
complete. And proper piping means
quick, clean installations for the
heating professionals who are doing
the work.
As boilers continue to get smaller
and the spaces in which they are
placed are reduced in size, our
hydronic packages allow for consid-
erable functionality in a very econom-
ical space.
Complete Packages to Purge, Quiet, Fill,
and Service Your Hydronic System

PIPF-T System Purge Station
During commissioning, by closing the Series PIPF-T’s ball valve and connecting a hose to the purge fitting, an installer can push all of the initial air out of the
system. PIPF-T replaces up to seven fittings with a single compact unit.
AS-MB Air Separator
The AS-MB Air Separator employs rugged, corrosion-resistant coalescing media and a Duo Vent air vent assembly to provide microbubble air separation for
a quieter heating system. The unit is fully serviceable in the field and comes in a
flanged model designed to mate with the PIPF-T System Purge Station.
RBFF Service Fitting
Setting a new standard for fast and easy service calls, the RBFF Service Fitting
is connected below the AS-MB Air Separator. The RBFF employs a unique
3-way ball valve for isolation of the water pressure regulator and expansion tank
from system pressure. The RBFF Service Fitting’s drain port allows for unloading pressure from the waterside of the expansion tank diaphragm for air charge
servicing and maintenance. Compared with traditional installations, the RBFF’s
one-piece construction eliminates up to 11 threaded joints.

B911S-M3 Fill Valve Assembly
The B911S-M3 Fill Valve Assembly, a combination high-capacity fill valve,
backflow preventer, and feed water pressure regulator, is packaged in one preassembled unit. This valve is designed for use on boiler feed lines to provide
make-up water to the boiler and prevent backflow when supply pressure fails
below system pressure.
ETX Expansion Tank
Series ETX non-potable expansion tank is for use in closed loop hydronic heating system piping to control the thermal expansion of hot water and maintain
system pressure below the relief setting of the relief valve.
