PEX
FITTINGS
The August 9, 1999 edition of the Monday Morning Messenger I reported the
following...........
While looking at this brand
new home I encountered a new fitting that I had yet to encounter
previously.
 I
first noticed them in the interior basement water main shut off.
The pipe was clear and the joint fitting looked to be a plastic
sleeve that was slid over the top of the connection. The connectors
were a combination of plastic and brass. All of the connections
looked to be made without any glue joints.
The interesting thing was that there was not a typical PEX
manifold and at each turn there were fittings. Up until now all
of the PEX that I have been encountering were in manifold systems
without any in wall splices. Instead, there were large bends and
loops in the lines. I had been told that this also helped with
the expansions and contraction in the lines. This installation
left no major slack areas for expansion and contraction.
 The
PEX used in this home was marked with the following..... WIRSBO
AQUAPEX 3/4 IN SDR9/ sa B137.5 POTABLE/ NSFP-4/ ASTMF876/F877/
ICBO ES ER5142 HAUSER/ SBCCI PST & ESI 9661 / 160PSI 73.4f/
100 PSI 180f/ 80 PSI 200f WIRSBO-PEX-a TUBING UNI6990209 07356
.... This is quite a bit of information and it is printed over
and over on the lines. The tubing was not the normal red and blue.
Instead, it was all milky white in color.
I was going to throw up the question to all of you as to what
types of fittings these were and then I blindly stumbled onto
the manufacturer's website. The following is their description
of the product at www.wirsbo.com.
Wirsbo AQUAPEX® --
The Future of Plumbing
Current problems with corrosive water,
leaky fittings and disintegrating pipe have left the plumbing
industry looking for a reliable solution. AQUAPEX® is the
answer. AQUAPEX® uses AQUAPEX® tubing (Engel), which is
cross-linked polyethylene (PEX) tubing for hot and cold potable
water service and distribution. Wirsbo PEX tubing has been used
in plumbing systems around the world for over 25 years, longer
than any other flexible plumbing system available.
AQUAPEX® is a logical choice for
modern plumbing systems because it offers many advantages over
rigid metal and other plastic tubing.
- Its light, flexible nature makes it
installation-friendly reducing labor costs.
- Its non toxic formula makes it completely
clean, healthy and safe. Concerns about lead, copper and other
toxins leaching into drinking water are eliminated.
- Its smooth, cross-linked structure
makes it resistant to corrosion. AQUAPEX® tubing will not
corrode, pit or scale.
- A 25 year track record means it is
proven effective in plumbing.
- Its unique ProPEX® fitting system
is the most reliable system on the market. AQUAPEX® systems
even come with a 25 year warranty when they are installed by
a Wirsbo trained installer.
The AQUAPEX® system boasts the best
fitting system in the industry -- ProPEX®. ProPEX® fittings
use the shape-memory of AQUAPEX® tubing. Using the hand-held
ProPEX® expander tool, the tubing and a PEX ring are expanded
and the fitting is inserted. The tubing then compresses around
the fitting as it tries to return to its original shape.
The connection
is permanent, leak-proof and proven reliable. Wirsbo also offers
an electrically powered automatic ProPEX® expander tool for
even faster, easier connections.
A Home Run: The flexibility of AQUAPEX®
tubing allows alternative installation methods that minimize the
pressure drops that result when two fixtures operate simultaneously.
Using the Home Run method, centrally located manifolds distribute
water to each fixture with dedicated hot and cold water lines.
The Home Run method requires fewer fittings, helping to eliminate
leaks and keeping overall material cost competitive.
Wirsbo's AQUAPEX tubing has the incredible
property of thermal memory. If the tubing becomes kinked, heating
it up with a heat gun will make it transparent and return it to
its original shape and strength. The tubing returns to its natural
opaque color when cooled.

Code Approvals: AQUAPEX tubing is manufactured
and listed to ASTM F876, F877, and F1960 for use in hot and cold
potable water distribution systems. It is approved by BOCA, CABO,
ICBO 5142, SBCCI, IPC for potable hot and cold water distribution,
and by IPC and SBCCI for water service. It has IAPMO Acceptance.
AQUAPEX® is approved in many states, cities and counties around
the United States and Canada. Check with your local code official
for further code information.
AQUAPEX® tubing undergoes the most
exhaustive testing of any material on the market. Wirsbo PEX undergoes
an extensive battery of tests internally, and through an independent
third party testing agency. Wirsbo PEX tubing currently holds
the unofficial world record for long-term testing at elevated
temperatures and pressures -- 23 years at 203 ° F at 152 psi,
and still going. The record will be official when the testing
is complete.
AQUAPEX® tubing is rated at 180°
F at 100 psi, 200° F at 80 psi and 73.4° F at 160 psi.
