Festo
531658
Quick coupling plug KS2-M5-A
The Festo part number 531658 is an industrial component featuring an M5 external thread pneumatic connection 1 and a nominal width of 2.4 mm, constructed from nickel-plated brass with an NBR and high-alloy stainless steel 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) and an ambient temperature range of -10 °C to 60 °C, supporting compressed air media per ISO 8573-1:2010 [7:-:-] with optional lubricated operation. Weighing 5 g with a CRC rating of 1 and VDMA24364-B1/B2-L LABS conformity, this RoHS compliant part requires a nominal tightening torque of 0.85 Nm with a ±15% tolerance to achieve normalized flow rates between 85 l/min and 136 l/min (ISO 8778 standardized flow of 92.1 l/min to 147.4 l/min).

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.
