•
No disassembly required. Instead,
the installer simply pushes the
conduit or tubing onto the ferrule,
then tightens the domed sealing nut.
This completed assembly can then
be secured in the panel by the
locknut or into an NPT threaded hole.
•
Convex ferrule ensures liquid tight seal.
•
No threading of the conduit or tubing
is required to install. This eliminates
the possibility of cutting the conduit
and creating leak paths.
•
Complete conduit/connector system
is reusable. Conduit will not wind
tight onto the connector during
assembly and can be easily removed
by pulling while turning in a
clockwise direction.
•
Multiple sizes for use with
Heyco-Flex Conduit and Tubing.
See pages 2-7 and 2-8.
•
Suitable for indoor/outdoor use; for
original equipment manufacturers or
field installers.
•
Use of a sealing washer may be
required for wet locations.
See page 2-19.
•
All nylon construction resists salt
water, weak acids, gasoline, alcohol,
oil, grease, and common solvents.
(This feature is not assessed by UL
certification and testing.)
•
If using a tapped hole, Teflon
®
tape is
needed on the threads of the connector,
for all other applications an O-ring and
Locknut are needed to attain liquid tight.
•
Black connectors up to 1˝ provided
with nylon locknut, packed separately.
O-ring sold separately, see page 2-20.
•
Black connectors larger than 1˝ and
all gray connectors provided with
assembled O-ring and metal locknuts.
•
See pages 2-17 and 2-18 for locknuts.
