Festo
153421
Push-in fitting, self-sealing QSMK-1/4-6
This Festo industrial component features a straight design with a standard size and a nominal width of 3 mm, utilizing a push-pull structural design with a coating on the screwed plug seal. It operates with compressed air according to ISO 8573-1:2010 [7:-:-] across an ambient temperature range of -10 °C to 80 °C, supporting lubricated operation and accommodating approved PAN, PEN, PFAN, PLN, PTFEN, and PUN tubing types with a 13.5 mm insertion depth. The unit provides an operating pressure of -0.095 MPa to 0.6 MPa (-0.95 bar to 6 bar; -13.775 psi to 87 psi) for the entire temperature range, and a temperature-dependent operating pressure from -0.095 MPa to 1.4 MPa (-0.95 bar to 14 bar; -13.775 psi to 203 psi) with a nominal tightening torque of 9 Nm at a tolerance of ±20%.

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.
