³⁄₈
" AQUAPEX ProPEX Connections
The
³⁄₈
" PEX ring is smaller and thicker than the PEX rings used for
other tubing sizes. The
³⁄₈
" PEX ring must expand once on each side
to properly fit over the tubing. Expansion of the PEX ring is only
necessary for
³⁄₈
" AQUAPEX.
1. Square cut the
³⁄₈
" AQUAPEX tubing perpendicular to the length
of the tubing.
2. Expand each side of
³⁄₈
" PEX ring with the ProPEX Expander
Tool once.
3. Slide the expanded
³⁄₈
" ring over the end of the tubing. Extend
the end of the ring over the end of the tubing no more than
¹⁄₁₆
" (1mm).
Once the
³⁄₈
" PEX ring is properly expanded and on the tubing, refer
to Steps 3 - 5 on
pages 8 and 9
(Making ProPEX Connections) for
further instruction.
Important Tips for a Proper
³⁄₈
" ProPEX Connection
• When the temperature is above 40°F, ProPEX connections to
³⁄₈
"
AQUAPEX tubing require four to five expansions. When the
temperature is below 40°F, only four expansions are necessary.
• The thicker PEX ring used for
³⁄₈
" ProPEX connections shrinks over
the fitting faster than other size PEX rings.
