Festo
153191
Push-in T-fitting QSTF-1/2-12-B
The Festo 153191 is a standard-sized, L-shaped industrial component featuring an additional connection with an internal thread lengthwise, a 10 mm nominal width, and a 23.4 mm tubing insertion depth utilizing a push-pull structural design. It operates with compressed air or liquid water across a temperature range of -10 °C to 80 °C, supporting variable operating pressures up to 1.4 MPa depending on temperature and a maximum pressure of 0.6 MPa for water at up to 50 °C. Constructed with a coated screwed plug seal, 2 outlets, 1 supply line, and a product weight of 100 g, this unit meets ISO 14644-1 Class 4 cleanroom standards and features CRC 1 low corrosion stress.

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.
