Festo
153291
Push-in fitting, self-sealing QSMK-M5-4
This straight-design Festo industrial component features a 1.4 mm nominal width, a standard size, and a push-pull structural design with an integrated sealing ring on the screwed plug for mounting in any position. It accommodates a wide range of approved tubing types with a 12.7 mm insertion depth, operating on compressed air in accordance with ISO 8573-1:2010 [7:-:-] across an ambient temperature range of -10 °C to 80 °C. The unit supports an operating pressure of -0.095 MPa to 0.6 MPa over its entire temperature range and -0.095 MPa to 1.4 MPa under temperature-dependent conditions, utilizing a nominal tightening torque of 1.2 Nm with a ±20% tolerance.

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.
