Quick couplings
Hoses
Nitto Kohki supplies polyurethane compressed-air hoses in the NKU and NKC series, matched to HI Cupla quick couplings. The nine-item range covers various outer diameters and lengths: NKU-605B, NKU-610B, NKU-620B (6 mm OD), NKU-810B, NKU-820B (8 mm), and the NKC series in 5 and 6 mm (NKC-503B, NKC-505B, NKC-603B, NKC-605B). All hoses are polyurethane with NBR coupling inserts.
Polyurethane (PU) hoses offer good abrasion resistance, flexibility at low temperatures and low self-weight. The part number coding indicates outer diameter (5, 6 or 8 mm) and length in metres, for example NKU-610B denotes 6 mm diameter, 10 m length.
