Festo
153279
Push-in L-fitting QSLF-1/4-10-B
The Festo 153279 is an L-shaped industrial component featuring an 8 mm nominal width, a 20.2 mm tubing insertion depth, and an external hexagon SW17 mounting type with a nominal tightening torque of 9 Nm at a ±20% tolerance. Utilizing a push-pull structural design, this standard-sized part operates with compressed air according to ISO 8573-1:2010 [7:-:-] or ice-free liquid water, supporting lubricated operation and featuring an operating pressure range of -0.095 MPa to 1.4 MPa depending on temperature. It weighs 27 g, holds a CRC 1 low corrosion stress rating, meets VDMA24364-B1/B2-L LABS conformity, and achieves ISO 14644-1 Class 4 cleanroom suitability for ambient temperatures between -10 °C and 80 °C. This pack of 10 components can be mounted in any position. Submit the exact part number, quantity, and application requirements to request a quote.

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.
