Summary Description
Nitto Hi‑Cupla male insert couplers in ½″, ¾″, and 1″ sizes provide robust pneumatic connections via quick‑connect plugs with male BSPT threading. The standard versions (40PM, 600PM, 800PM) offer high flow and reliability, while the PVR versions (PVR‑400PM, PVR‑600PM, PVR‑800PM) incorporate enhanced safety features—purge valves and locking sleeves—to safely release pressure and prevent hose whip.
Let me know if you’d like detailed dimensions, part numbers for specific configurations (e.g., stainless steel), or where to source them locally in South Africa!
