Festo
531627
Quick coupling socket KD3-1/8-I
The Festo part number 531627 is an industrial component featuring a nominal width of 5 mm and an internal thread G1/8 pneumatic connection 1, operating across a pressure range of -0.095 MPa to 1.2 MPa (-0.95 bar to 12 bar / -13.775 psi to 174 psi). Constructed with a nickel-plated brass housing and threaded coupling, NBR seals, and high-alloy stainless steel spring, ball, and circlip materials, this 32 g unit achieves a normal nominal flow rate from 185 l/min to 603 l/min and an ISO 8778 standardized flow rate of 200.5 l/min to 653.7 l/min with compressed air per ISO 8573-1:2010 [7:-:-]. It operates within an ambient temperature range of -10 °C to 60 °C, supports lubricated operation, and requires a nominal tightening torque of 5 Nm with a ±15% tolerance while meeting CRC 1 corrosion resistance, VDMA24364-B1/B2-L LABS conformity, and RoHS material compliance.

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.
