The FLIR A3xx pt series camera comes with two ¾″ NPT cable glands, each with a three-
hole gland seal insert. Cables can be between 0.23″ and 0.29″ OD. Up to six cables may
be installed. Plugs are required for the insert hole(s) not being used.

If non-standard cable diameters are used, you may need to locate or fabricate the appro-
priate insert to fit the desired cable. FLIR Systems does not provide cable gland inserts
other than what is supplied with the system.
Insert the cables through the cable glands on the enclosure before terminating and con-
necting them. (In general, the terminated connectors will not fit through the cable gland.) If
a terminated cable is required, make a single clean cut in the gland seal to install the cable
into the gland seal.
Proper installation of cable sealing glands and use of appropriate elastomer inserts is crit-
ical to long-term reliability. Cables enter the camera mount enclosure through liquid-tight
compression glands. Be sure to insert the cables through the cable glands on the enclo-
sure before terminating and connecting them (the connectors will not fit through the cable
gland). Leave the gland nuts loosened until all cable installation has been completed. In-
spect and install gland fittings in the back cover with suitable leak sealant, and tighten to
ensure water-tight fittings. PTFE tape or pipe sealant (e.g., DuPont RectorSeal T) is suit-
able for this purpose.
