Festo
186108
Push-in fitting QS-G1/4-6-I
This Festo industrial component, part number 186108, features a straight design with a standard size, a 4.2 mm nominal width, and a 17 mm tubing insertion depth utilizing the push-pull principle. It operates with compressed air according to ISO 8573-1:2010 [7:-:-] or liquid, ice-free water across an ambient temperature range of -10 °C to 80 °C, and accommodates 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. Each pack size contains 10 units weighing 13 g each, featuring a sealing ring on the screwed plug and an internal hexagon AF 4 for mounting with a nominal tightening torque of 9 Nm at 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.
