Re-piping is possible.
Repeated re-piping of up
to 6 to 10 times is possi-
ble due to use of elastic
sealant on seating.
Sealant tape is necessary
because sealant becomes
separated with repeated in-
stallation.
Prevention of sealant residue/protrusion
The current sealant type leaves residue and protrudes out
from the threading when installing, making it necessary to
clear away the residue using an air blower or similar.
However, no residue is created when using a face seal.
Number of rotations
after hand-tightening
