Paint Cupla

Nitto Kohki Paint Cupla quick-release couplings are engineered specifically for paint and coating applications where solvent resistance, zero spill-back, and low connection force are critical. The one-touch sleeve-lock mechanism allows single-handed connection and disconnection under pressures up to 1.0 MPa (145 psi), while the precision-machined stainless steel and polyacetal internals deliver a fluid-tight seal with a leakage rate of <0.1 cm³/min. Colour-coded body variants and size-coded nipples prevent accidental cross-connection between incompatible media lines, a key requirement in multi-gun spray systems conforming to CE Machinery Directive 2006/42/EC.

As an authorised distributor for Nitto Kohki pneumatic components, esd.equipment supplies the full Paint Cupla range - 4 catalogue items available from stock - covering socket and plug variants in standard and mini series. All couplings comply with ISO 6150 class B interchangeability criteria and are rated for continuous service with water-based and solvent-based paints, lacquers, and adhesives.

Typical application areas: Automotive body-shop spray lines (VDA 6.3, ISO 9001), industrial powder and wet-paint coating systems (IEC 60079 zone-2 compatible configurations), furniture and wood-product lacquering lines, aerospace surface treatment (AS9100), electronics conformal coating (IPC-CC-830), and general-purpose pneumatic tool connections in paint booths and finishing facilities.
