How it connects
Prepared cable is inserted over an inner tubular post (mandrel) between dielectric and braid/jacket. An axial compression tool slides an outer collar forward, compressing the jacket into a 360-degree radial, watertight seal.
Male and female halves
Female cable socket/entry port that accepts and permanently captures a prepared male bare RG-6 coaxial cable end.
Usually connects to
- Prepared RG11 plenum coaxial cable compatible with the connector’s conductor, dielectric and jacket dimensions
- prepared (stripped) RG-6, RG-6 quad shield, RG-59 or RG-11 coaxial cable
Common sizes
- Cable-specific fits: RG-59 about 6.1 mm OD; RG-6 about 6.86–7.1 mm (0.270 in); RG-6 Quad Shield about 7.57 mm (0.298 in); RG-11 about 10 mm.
- Universal RG-6 versions accept dual and quad shield.
- RG11 plenum 92-212 example: 18–14 AWG solid conductor, 0.270–0.280 in dielectric and 0.340–0.356 in jacket. These are cable-fit ranges, not universal bore sizes.

Variations
- Cable-specific RG-6 dual-shield or universal dual/quad-shield entry
- RG-59 and RG-11 F compression entries
- RG11 plenum-specific entry, distinct from ordinary RG11
- Weatherproof O-ring version
- BNC or RCA compression version
- Other cable sizes require matching compression bodies
How to recognise it
Circular rear port of an uninstalled coax fitting featuring an internal tubular brass mandrel and an outer plastic or metal compression sleeve/ring awaiting axial compression.
Often confused with
| Confused with | How to tell them apart |
|---|---|
| Hex crimp RG-6 cable entry | Hex crimp uses an external metal ferrule deformed into a hexagonal shape with crimp pliers, whereas compression uses an axial sliding sleeve producing a uniform round 360-degree seal. |
| Twist-on / screw-on RG-6 cable entry | Twist-on fittings thread directly over the outer jacket by hand without tools or sliding sleeves. |
| F-type connector mating interface | The F-type mating interface is the 3/8-32 UNEF threaded front nut; the compression cable entry is the rear receptacle where raw coax cable terminates. A female F jack mates with an F male plug. This interface receives stripped cable inside a rear compression sleeve. |
| Plumbing compression fitting | This terminates concentric coax conductors using an axial compression tool; it does not use a pipe compression nut and olive. |
| Ordinary RG11 compression cable entry | Verify all cable dimensions and the plenum-specific part number; an RG11 label alone does not establish fit. |

Good to know
Describes the cable-side termination interface of a connector rather than the front mating interface (such as male F-type, BNC, or RCA).
