Confirm the part fits before you buy. Applications and interchange numbers are researched and audited per part.
We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
The coupler accepts standard industrial interchange plugs (Foster 3–6, Parker 20-series, Hansen 1000/400/500) for rapid connection and disconnection of air lines. The flange mount provides a secure, vibration‑resistant attachment point on compressors, air tanks, or manifolds, making it useful in heavy‑duty truck and trailer air systems where air lines must be frequently removed for service or configuration changes.
