Nitto Hi-Cupla Air Coupling Plug — 1/4″ Male Thread (20PM)
Part No: 20PM | Barcode: 16923 | Series: Hi-Cupla
The Nitto 20PM is a genuine Nitto Kohki Hi-Cupla air coupling plug that threads into a 1/4″ female port on an air tool, blow gun or manifold and plugs into a matching Hi-Cupla socket. The plug is the male half that clicks into any matching Hi-Cupla socket for safe, one-hand connect and disconnect. Built from heat-treated steel for long workshop life.

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.
- 1/4″ BSPT male thread — threads directly to 1/4″ air outlets, tools and manifolds for a permanent leak-free joint (use thread tape on the parallel face).
- 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 20PM when you need the male half of an air connection — it threads into a 1/4″ female port on an air tool, blow gun or manifold 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 20-series socket. Pair it with the matching halves in the table below — every Nitto 20-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.
