Festo
9425
Bulkhead quick connector QCK-1/8-PK-4-B
The Festo part number 9425 is an industrial bulkhead component featuring a 3.4 mm nominal width, a G1/8 internal thread pneumatic connection 1, and a connection for 6 mm outside diameter pneumatic tubing or 4 mm inside diameter barbed fitting with a nut for pneumatic connection 2. This part operates across a pressure range of -0.095 MPa to 1 MPa (-0.95 bar to 10 bar or -13.775 psi to 145 psi) with compressed air as per ISO 8573-1:2010 [7:-:-] and allows lubricated operation within an ambient temperature range of -10 °C to 60 °C. Constructed with an anodized wrought aluminum alloy connector and union nut, a galvanized steel nut, and a sealing ring on the screwed plug, the component achieves corrosion resistance class 1 and VDMA24364-B1/B2-L LABS conformity.
