IMPORTANT NOTE
Pressure Restrictions
Rectangular flange mount cylinders
(style RF) are not recommended for use
at the full operating pressure ratings
shown in separate Engineering Brochure.
Some methods of employing a cylinder
with a rectangular mount can produce a
condition where flexure of the flange can
result in fatigue failure of the mounting
bolts or flange retainer fasteners. If
pressures in excess of those shown in the
chart below are anticipated, a more rigid
mount such as an RFX or RHF should be
selected. Whenever there is doubt, select
an RHF mount.
