Festo
8085657
Push-in fitting NPQR-DK-M5-Q4
The Festo part number 8085657 is a straight industrial component featuring a 2.1 mm nominal width, a 14 mm tubing insertion depth, and a push-pull structural design with a sealing ring on the screwed plug. Operating across a pressure range of -0.095 MPa to 1.6 MPa (-0.95 bar to 16 bar or -13.775 psi to 232 psi) for compressed air and up to 0.7 MPa at 0 to 80 °C for water, this standard-sized component accommodates an ambient temperature range of -20 °C to 150 °C at a nominal tightening torque of 1 Nm. It provides a corrosion resistance class of 4 for particularly high corrosion stress, meets VDMA24364-B2-L LABS conformity, is suitable for Li-ion battery production with reduced Cu/Zn/Ni values, achieves ISO 14644-1 Class 4 cleanroom suitability, and holds NSF C0556009 certification along with NSF/ANSI 169 food industry suitability.
