ASTM F1960 Grip
™
American Society for Testing and Materials (ASTM)
Standard Specication for Cold-Expansion Fittings
With PEX Reinforcing Rings for Use with Cross-linked
Polyethylene (PEX) Tubing.
F1960 Installation
3. Using tube expander, expand sleeve
fully. Repeat expansions, rotating
expander 1/8-turn between
expansions. Note: To limit the amount
of time for tube compression onto
tting in cold environments, expand the
tube/sleeve slowly and only enough to
fully insert the tting. Keeping sleeves
warm will speed retraction and inhibit
unequal expansion.
5. The installation is complete with a
visibly secure connection. Remove
defective connections.
Test completed joint.
1. Cut tube at 90-degrees. Do not
crush OD of tubing with cutters.
Hint: Slightly rotate cutter during
blade engagement.
2. Install PEX sleeve onto OD
of tubing.
4. Insert tting into expanded tube
and sleeve. Assure proper expansion
so that tting is touching tube and
sleeve. Hold tting in place until tube/
sleeve memory constrict annularly
around the tting.
F1960 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.
F1960 compression rings are PEX.
Compression is made by placing a compression ring
onto tube, expanding PEX tube and ring, inserting a
full-ow tting, and holding in place until tube / ring
memory secures the connection.
Handling requirements are included within the
Fitting / Ring Limitation Section.
Fittings are reusable if barb is undamaged.
