Pressure and Vacuum Rating
Garlock PTFE expansion joints and couplings have
pressure ratings high enough to handle most applica-
tions. As the pipe size gets larger, Garlock increases
the bellows thickness and the strength of the reinforc-
ing rings to compensate for the change in internal
forces. This permits the same high pressure rating for
all sizes.
These PTFE concentric spool-type fexible cou-
plings are designed to reduce noise and compensate
for expansion, contraction and minor piping misalign-
ment in chemical processing, air conditioning and
heating systems.
