Push-in fittings NPQP, media resistant
Push-in fittings
Festo NPQP push-in fittings are designed for contact with aggressive media including oils, coolants, some solvents and wet compressed air that would attack standard plastic materials. The code -FD in the part number identifies the media-resistant version. The range covers L, T and Y forms as well as bulkhead fittings (NPQP-H).
Thread connections R1/4, R3/8 and R1/2, as well as threadless push-in connectors (suffix -E) for tube-to-tube applications, are available. Tube outside diameters 4, 6, 8, 10 and 12 mm are represented. Many types come in packs of 10 (P10).
| Type | Form | Thread | Tube OD |
|---|---|---|---|
| NPQP-LQ-R14-Q10, R38-Q10, R38-Q12 | L elbow | R1/4, R3/8 | 10, 12 mm |
| NPQP-LQ-R12-Q12 | L elbow | R1/2 | 12 mm |
| NPQP-T-R14-Q10, R38-Q10, R38-Q12 | T-piece | R1/4, R3/8 | 10, 12 mm |
| NPQP-Y-R14-Q10, R38-Q10, R38-Q12 | Y-piece | R1/4, R3/8 | 10, 12 mm |
| NPQP-H-Q4 to -Q12-E | Bulkhead fitting | Threadless (E) | 4, 6, 8, 10, 12 mm |
| NPQP-T-Q10-E, NPQP-Y-Q10-E | T / Y threadless | Threadless (E) | 10 mm |
Typical applications: Coolant circuits and lubrication oil supply in machine tools, media routing with synthetic oils in hydraulic power units, compressed air systems with oil injection (mist lubrication), solvent cleaning installations, and generally wherever standard plastics are attacked by the process medium.
