531630

Quick coupling socket KD3-CK-6

The Festo 531630 is an industrial pneumatic component featuring a 4.9 mm nominal width and an operating 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, brass valve body, NBR seals, high-alloy stainless steel springs, balls, and circlips, this 32 g unit accommodates compressed air media per ISO 8573-1:2010 [7:-:-] with a normal nominal flow rate of 180 l/min to 468 l/min (195.1 l/min to 507.3 l/min standardized to ISO 8778). It includes pneumatic connection 1 for 8 mm outside diameter tubing or barbed fittings with a 6 mm inside diameter using an anodized wrought aluminum alloy union nut, and supports lubricated operation within an ambient temperature range of -10 °C to 60 °C.

Why 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.

Identification and RFQ Guidance

Confirm the exact configuration

Use the manufacturer part number and model code—not appearance alone. Connection, size, material, voltage, pressure, seal, and control options can differ within the same product family.

What to include in your RFQ

Provide quantity, delivery country and ZIP/postal code, required condition, target date, and photographs of the existing nameplate when available.
