•
Smooth internal surfaces for easier
wire installation around corner angles.
•
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.
•
Lower installed cost.
•
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.
•
Resist salt water, weak acids, gasoline,
alcohol, oil, grease, and common
solvents. (This feature is not assessed by
UL certification and testing.)
•
Use of a sealing washer may be required
for wet locations. See pages 2-19.
•
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 locknut.
•
See pages 2-17 and 2-18 for locknuts.
