If a 5-conductor headset plug will not fully seat in a mono push-to-talk jack, you often need a depth spacer—not a different radio connector.

The seating problem

PlugTypical useNotes
TP-101 (U-174/U)Mono PTT jacks (Constant Able, most U-94s)4-conductor · shorter
TP-105 (U-384/U)Many dual-channel / stereo-class plugs5-conductor · longer

Forced into a mono jack without a spacer, a TP-105 often does not seat—intermittent audio or no connection. Common on dual-comm style plugs, including many Atlantic Signal–modified dual-channel Peltors.

Different product: Atlantic Signal MH-180 bone-conduction headsets are a mic-path issue (dynamic → correct amp path), not an O-ring seating fix.

What the O-rings do

They act as a standoff so the plug reaches proper depth in a mono TP-101 jack.

In a mono PTT jack, audio is treated as mono-binaural. That is plug-depth correction only—not a second PTT and not full dual-net architecture. For true two-net setups see Dual Comms.

Next steps

  1. Confirm a TP-105 / 5-conductor style plug (or AS-mod dual-channel Peltor).
  2. Order the O-Ring Pack.
  3. Match the radio PTT in the PTT Selector (choose Atlantic Signal mod when that applies).
