Key Features & Benefits
- Genuine Nitto Kohki Hi-Cupla — the industry-standard one-touch air coupling used across Australian workshops, so it interchanges with the Nitto-pattern fittings you already own.
- One-hand connect and disconnect — the plug clicks straight into the socket and releases with a single sleeve pull, no spanner or thread tape needed.
- 3/8″ hose tail (suits 10mm air hose) — barbed tail clamps securely onto 3/8″ air hose for a reliable, vibration-proof hose connection.
- Heat-treated steel construction — critical wear parts are hardened for long service life on busy compressed-air systems.
- 1.5 MPa working pressure — rated to 215 psi, well above typical 100–120 psi shop air, with a generous safety margin.
When to Use This Fitting
Reach for the Nitto 30PH when you need the male half of an air connection — it push-fits onto the end of 10mm (3/8″) air hose with a clamp and plugs into a matching Hi-Cupla socket. Plugs are the parts that travel: fit one to each air tool, blow gun or hose whip so any of them drops into a shared 30-series socket. Pair it with the matching halves in the table below — every Nitto 30-series plug and socket inter-connects regardless of whether the back end is a thread or a hose tail.
Pro Tip: Nitto-pattern is one of several incompatible quick-coupler standards (Nitto, ARO, CEJN and Euro all look similar but will not seat together). Standardising your whole shop on the Nitto Hi-Cupla pattern shown here means any plug mates with any socket across the 20, 30 and 40 sizes.
