Compatibility Chart
Approved Tubing for use with
Ultra-Fin is typically designed and installed with 1/2" tubing (5/8" O.D.). Larger diameter
PEX tubing may be used up to 3/4" (7/8" O.D.) with larger sized Turnkeys speciîżed.
CAUTION!
Do Not use tubing with an EVOH barrier on the exterior of the tubing. However tubing
manufactured with a polyethylene layer or non-friction coating extruded over the EVOH
oxygen barrier is approved.
Using a tubing brand from our Approved Tubing List will ensure a silent interface
between the PEX tubing when attached or crossing wood joist.

Other brands of PEX tubing may be acceptable, please check with an Ultra-Fin
representative.
Installing other types of tubing may create a slight ticking noise as the tubing expands
during operation. This noise is created by the outer layer of the EVOH barrier when it is
in direct contact with wood.
