Festo
153321
Push-in fitting QSM-M7-6-I
The Festo 153321 is a mini straight industrial component featuring a 4.1 mm nominal width, a 12 mm tubing insertion depth, and an M7 external thread pneumatic connection 1 with a sealing ring on the screwed plug. Operating via the push-pull principle, this unit handles an operating pressure of -0.095 MPa to 0.6 MPa across its entire temperature range, and -0.095 MPa to 1.4 MPa under temperature-dependent conditions using compressed air per ISO 8573-1:2010 [7:-:-] with lubricated operation possible. Designed with any mounting position, an internal hexagon AF 4 mounting type, a nominal tightening torque of 2.2 Nm with a ±20% tolerance, and a product weight of 6.4 g, it functions within an ambient temperature range of -10 °C to 80 °C, a corrosion resistance class of 1, and VDMA24364-B1/B2-L LABS conformity.

Request a QuoteWhy 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.
