Install Instructions

American Society for Testing and Materials (ASTM)
Standard Specication for Cold-Expansion Fittings
With Metal Reinforcing Rings for Use with Cross-linked
Polyethylene (PEX) Tubing.
4. Insert tting into the expanded
tube until the tting’s last barb is
1/16" from the end of the tube.
Mount the compression head forks of
the F2080 tool onto the tting yoke
(space between the two radial anges
on tting) and over the tube behind
the sleeve.
5. Compress the F2080 tool. The
sleeve will begin to move toward the
tting. Continue compressing until
the sleeve meets the surface of the
outside tting ange.
6. Inspect the secured joint. Assure
there are no visible gaps between
the sleeve and the tting ange.
Remove defective connections. Test
completed joint.
2. Slide F2080 sleeve at least 2"
onto the PEX tube. It must be in the
correct orientation. The sleeve end
with the machined groove on the
outer diameter should load onto tube
rst. The sleeve end with the tapered
lip on the inner diameter should face
toward the tting.
1. Cut tube at 90-degrees. Do not
crush OD of tubing with cutters.
Hint: Slightly rotate cutter during
blade engagement.
3. Insert expander head of the F2080
tool into the PEX tube. Use a series
of expansions and releases to slowly
expand tubing. Rotate the expander
head 45 degrees between expansions.
PEX-B tube expansions MUST be
made slowly.
F2080 Installation
F2080 ttings can be made from various certied,
listed and approved materials. See ASTM standard for
acceptable brass alloys. Assure your tting is made
from a listed material.
F2080 expansion sleeves are metal.
Compression is made by placing an expansion sleeve
onto tube, expanding PEX tube, inserting a full-ow
tting, and pulling the sleeve up over the tting and tube
to secure the connection.
