Festo
153443
Push-in connector, self-sealing QSK-12
The Festo 153443 is a standard straight-design industrial component utilizing a push-pull structural design with a 6.2 mm nominal width and a 23.5 mm tubing insertion depth for 12 mm outside diameter pneumatic tubing on both connections. It operates with compressed air according to ISO 8573-1:2010 [7:-:-] across an ambient temperature range of -10 °C to 80 °C, supporting lubricated operation and featuring a corrosion resistance class of 1 alongside VDMA24364-B1/B2-L LABS conformity. Operating pressure spans -0.095 MPa to 0.6 MPa for the entire temperature range and -0.095 MPa to 1.4 MPa dependently, with a total product weight of 40.5 g and an optional mounting position in any orientation.

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.
