Click fittings
Fittings
Festo NPKA click fittings combine the push-in principle with an audible click mechanism that signals correct tube engagement. The range consists of three base types: straight fitting (NPKA-D-G18-Q6-P10), T-connector (NPKA-T-Q6-E-P10) and L-fitting (NPKA-L-G18-Q6-P10). All types are rated for 6 mm tube OD and are supplied in packs of 10.
Click mechanism - audible and tactile feedback confirming correct tube locking
G1/8 thread (NPKA-D, NPKA-L) - parallel BSP thread for straightforward installation
Threadless T-connector (NPKA-T-Q6-E) - tube-to-tube, three outlets
Pack of 10 (P10) - all three types available in 10-piece packs
| Type | Form | Thread | Tube OD |
|---|---|---|---|
| NPKA-D-G18-Q6-P10 | Straight fitting | G1/8 | 6 mm |
| NPKA-T-Q6-E-P10 | T-connector | Threadless (E) | 6 mm |
| NPKA-L-G18-Q6-P10 | L-fitting (90°) | G1/8 | 6 mm |
Typical applications: Assembly lines with high volumes of tube connections where an audible click confirms a correct joint without visual inspection, handling devices with frequent tube wear, and 6 mm tube OD applications at G1/8 ports.
