Frequently asked questions
With which plumbing standards is this offering compatible?
The offering is compatible with ASTM B88 Type K, L or M copper
pipe and ASME B16.51 copper press ttings.
What is the operating temperature range for these adapters?
For hot and cold potable water, chilled water and hydronic
heating and cooling applications, the range is 0°F (-17.8°C) to
200°F (93.3°C). Note that the Plastics Pipe Institute (PPI) issues
the following operating temperature and pressure ratings for
PEX piping systems: 200°F (93.3°C) at 80psi, 180°F (82.2°C)
at 100psi and 73.4°F (23°C) at 160psi.
Are the adapters acceptable for use in direct-burial
applications?
Yes, however they must be wrapped with 6 mil poly material for
direct burial in soil or concrete.
How can I tell if the press process is complete?
The ½" to 2" press adapter connections display jaw marks
on the brass indicating a proper connection. The 2½" to 3"
press adapter connections feature a tag that breaks to indicate
a proper connection (note you must remove this tag after
completing the connection).
Where do I access installation instructions for the
Uponor adapters?
For press tting adapters, refer to the copper press tting
supplier’s installation instructions to verify a completed press
connection. For press adapters, refer to uponorpro.com/press.
Which press tools and jaws are approved for use with
the Uponor offering?
Refer to the charts on this page for the approved tools.
In what types of systems can I use these adapters?
The adapters are suitable for use in hot and cold potable water,
chilled water and hydronic heating and cooling applications.
Why don’t the 2½" and 3" press adapters have a
stainless-steel ring like other press adapters on the market?
The 2½" and 3" press adapters incorporate a patented design
that securely fastens the pipe and tting together, eliminating
the need for a ring.
