Default PEX and water pressure ratings


"Eigenvector" wrote in message
Aquapex meets ASTM F876 and F877, and is certified to NSF standards 14
and 61. It is rated by the PPI : 200°F at 80 psi, 180°F at 100 psi,
and 73.4°F at 160 psi.

Oooohh, that's cutting it pretty damn close.

Sounds like in a PEX environment keeping water pressure at 60psi or lower
would give a much better factor of safety.


What is cutting close? It can take 100 psi and 180 degrees. Your hot water
should be only about 125 or so.
Note: Wirsbo 1/2" AQUAPEX tubing is listed to UL1821 and ULC/ORD C199 P and
carries an additional rating of 120 degrees F at 130 psi.

Do you have pressure near 130?
