Product Overview

Application
The Pressure Test Kit allows users
to pressure test Uponor manifolds
and tubing.
Part Number
E6122000
Installation
1. Assemble the R32 x
3
⁄4" adapter,
3
⁄4" nipple and gauge assembly.
2. Thread this assembly into the
R32 manifold union nut.
3. Thread the R32 plug into the
other R32 manifold union nut.
Note: Manifolds come with a
gasket that seals the R32 union nut.
Use Teflon tape or pipe dope on the
3
⁄4" NPT threads.
Gauge Rating
100 psi
Pressure Testing
Pressure test the system with air
or water before covering the tubing.
Air testing is the preferred method.
Test each manifold separately or,
depending upon the construction
schedule, test the entire system at
one time. Refer to the following
recommended procedure for
pressure testing.
1. Be sure all connections are
properly sealed using the
supplied gask
ets.
2. On the end cap with vent, remove
the air vent and drain cock and
r
eplac
e with pr
operly sized plugs.
3. Install the Pressure Test Kit onto
the system.
4.
Pr
essurize the syst
em with air
to 60 psi. The system should
maintain the 60 psi for a
minimum of 24 hours.
5. Depending on installation
circumstances, the PEX tubing
may expand under pr
essur
e and
r
equir
e a one-time addition of air
to offset the tubing expansion.
Maintain pr
essure on the system
during the slab pour or when
installing finished flooring. This
simplifies leak detection if the
tubing is damaged during the pour
or installation. The pressure testing
procedure is a recommendation
from Uponor. Check local building
codes for compliance or additional
test requirements.
Note: Brass manifolds contain
valves that are not designed to
hold high pressure. Pressure testing
against these valves may result in
some leak
age and may c
ompr
omise
the test. Use appropriate end caps
or plugs t
o fur
ther seal the
syst
em as nec
