153423

Push-in fitting, self-sealing QSK-1/4-8

This Festo industrial component, part number 153423, features a straight design with a standard size, a 4.3 mm nominal width, and an 18.5 mm tubing insertion depth utilizing the push-pull principle. It operates with compressed air as per ISO 8573-1:2010 [7:-:-], supporting lubricated operation across an ambient temperature range of -10 °C to 80 °C and an operating pressure from -0.95 bar to 6 bar across the entire temperature range. The screwed plug utilizes a coating seal with a nominal tightening torque of 9 Nm at a ±20% tolerance, providing a corrosion resistance class of 1 and VDMA24364-B1/B2-L LABS conformity.

Why no listed price?

Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.

Identification and RFQ Guidance

Confirm the exact configuration

Use the manufacturer part number and model code—not appearance alone. Connection, size, material, voltage, pressure, seal, and control options can differ within the same product family.

What to include in your RFQ

Provide quantity, delivery country and ZIP/postal code, required condition, target date, and photographs of the existing nameplate when available.
