Push-in fittings
Push-in fittings NPQP, media resistant
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).
