Operating principle
- Simple design air line coupling on manifold.
- Enables several air lines to be taken simultaneously from one supply line.
- Just push in the plug into socket for simple and secure connection.
- Multiple outlets are available from single air supply source.
- Choose from the 2-outlet type (Model 200T), the 5-outlet straight type (Model 200L) and the 5-outlet star type (Model 200S) to suit your application.
- The products come with dustproof caps.

Choose LINE CUPLA 200 when two or five air lines have to be taken from one supply line at the same point, at a working pressure of up to 1.5 MPa {15 kgf/cm2}. MICRO CUPLA, SMALL CUPLA, COMPACT CUPLA, CUBE CUPLA and SUPER CUPLA are rated 1.0 MPa {10 kgf/cm2} and are therefore limited to lower pressure lines. Its couplings are one-way shut-off; where both sides of the line must close on disconnection, COMPACT CUPLA and CUBE CUPLA offer two-way shut-off, while LEVER LOCK CUPLA is straight through with no shut-off valve.
