Quick connect coupling Paint Cupla PE-3S-G, aluminium - Nitto Kohki 349823095

Paint Cupla is built for paint and coating lines. The socket is made of aluminium and seals with PFA, while the plug is made of stainless steel.

• PFA seal in the socket, chemically resistant to paints, solvents and cleaning agents
• Stainless steel plug body takes flushing and cleaning of the line in its stride
• Aluminium socket body keeps the coupling light to handle
• Models with G thread and with NPS thread within the range
• Connect and disconnect by hand, which shortens a colour change

Operating principle

• Unique swing connection system enables easy connection and disconnection of paint spray gun and paint hose even by gloved hands.
• Full-open gate valve mechanism prevents paint precipitate buildup.
• Adoption of special resin seal that has resistance against solvents made it possible to feature superior durability, long stable capability, and easy cleaning of paint spray gun after the job.
• Connection and disconnection can be made even if paint sticks to the socket sleeve.
• Small and lightweight design (80 g per set) reduces the weight to be held by hand of operators.
• Built-in sleeve lock mechanism prevents accidental disconnection of CUPLA, ensuring safe operation.
• Wide variety of end configurations (standard thread: G 3/8) are available in response to various paint spray guns.

Series comparison

Choose PAINT CUPLA where a solvent based paint line has to be connected and separated at the spray gun, since the fluoro-resin (PFA) seal and the full-open gate valve mechanism are specified for that fluid. Its working pressure is 1.0 MPa {10 kgf/cm2}, so a line that has to hold the 1.5 MPa {15 kgf/cm2} of peer series such as HI CUPLA BL, NUT CUPLA, LOCK CUPLA 200 or ROTARY LINE CUPLA calls for one of those instead. The shut-off is one-way, so where both halves have to close on disconnection COMPACT ZEROSPILL CUPLA with its two-way shut-off is the closer match.
