Festo
2154
Quick coupling plug KS4-1/4-A
The Festo 2154 is an industrial component featuring a nominal width of 7.85 mm and an external thread G1/4 pneumatic connection 1, constructed from nickel-plated brass with a PA66-GF30 and TPE-U threaded seal. It operates within a pressure range of -0.095 MPa to 1.2 MPa (-0.95 bar to 12 bar / -13.775 psi to 174 psi) across an ambient temperature of -10 °C to 60 °C, supporting compressed air media per ISO 8573-1:2010 [7:-:-] with optional lubricated operation. This RoHS-compliant part weighs 21 g, exhibits a corrosion resistance class of 1, and delivers a normal nominal flow rate of 756 l/min to 1323 l/min alongside a nominal tightening torque of 9.5 Nm with a ±15% tolerance.

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.
