Festo
153373
Push-in Y-connector QSMY-4-3
The Festo 153373 is a mini Y-shaped industrial component featuring a push-pull structural design with 1 supply line and 2 outlets for 4 mm and 3 mm outside diameter pneumatic tubing respectively. This unit operates on compressed air conforming to ISO 8573-1:2010 [7:-:-] with a nominal width of 1.6 mm, an 11.6 mm tubing insertion depth, and supports lubricated operation across any mounting position. It withstands an operating pressure of -0.095 MPa to 0.6 MPa over a temperature range of -10 °C to 80 °C, and a temperature-dependent operating pressure up to 1.4 MPa. Each pack contains 10 units with a product weight of 3.6 g each, a corrosion resistance class of 1, and VDMA24364-B1/B2-L LABS conformity.

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.
