Festo
153021
Push-in fitting QS-1/2-12-I
The Festo 153021 is a standard straight industrial component featuring an 8.4 mm nominal width, a 23.3 mm tubing insertion depth, and an R1/2 external thread for pneumatic connection 1 alongside a 12 mm outside diameter pneumatic tubing connection 2. It utilizes a push-pull structural design with a coated screwed plug seal, internal hexagon AF 8 mounting, and operates across an ambient temperature range of -10 °C to 80 °C with compressed air or liquid water. This unit weighs 45 g, has a CRC rating of 1, and supports operating pressures from -0.095 MPa to 0.6 MPa for water or up to 1.4 MPa depending on temperature.

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.
