Remove Moisture and Condensation
If condensation is present in any device, add a small desiccant packet to the inside of the radio. To help vent the radios, Banner also sells
a vented plug (model number BWA-HW-031) for the 1/2" NPT port of the SureCross radios.
Watertight Glands and NPT Ports
Watertight Glands and Plugs
To make glands and plugs watertight, use PTFE tape and follow these steps.
1. Wrap four to eight passes of polytetrafluoroethylene (PTFE) tape around the threads as close as possible to the hexagonal body of
the gland.
2. Manually thread the gland into the housing hole. Never apply more than 5 in-lbf of torque to the gland or its cable clamp nut.*
Seal any unused PG-7 access holes with one of the supplied black plastic plugs. To install a watertight PG-7 plug:
1. Wrap four to eight passes of PTFE tape around the plug’s threads, as close as possible to the flanged surface.
2. Carefully thread the plastic plug into the vacant hole in the housing and tighten using a slotting screwdriver. Never apply more than
10 in-lbf torque to the plastic plug.
* This is not a lot of torque and is equivalent to the torque generated without using tools. If a wrench is used, apply only very light pres-
sure. Torquing these fittings excessively damages the device.
Watertight NPT Plugs
Seal the 1/2” NPT port if it is not used. To install a watertight NPT plug:
1. Wrap 12 to 16 passes of PTFE tape evenly across the length of the threads.
2. Manually thread the plug into the housing port until reaching some resistance.
3. Using a 9/16” crescent wrench, turn the plug until all the plug’s threads are engaged by the housing port or until the resistance
doubles. Do not overtighten as this will damage the SureCross unit. These threads are tapered and will create a waterproof seal
without overtightening.
* This is not a lot of torque and is equivalent to the torque generated without using tools. If a wrench is used, apply only very light pres-
sure. Rotating these fittings excessively damages the device.
