Festo
186203
Push-in T-fitting QSTF-G1/4-8
This standard Festo industrial component, part number 186203, features an L-shape design with a nominal width of 6 mm, a tubing insertion depth of 18.1 mm, an internal thread lengthwise connection, and a sealing ring type of seal on the screwed plug. Utilizing a push-pull structural design, it operates at pressures ranging from -0.095 MPa to 0.6 MPa across the entire temperature range and up to 1.4 MPa under temperature-dependent conditions, accommodating compressed air and liquid water within an ambient temperature span of -10 °C to 80 °C. The unit weighs 44 g, maintains a nominal tightening torque of 9 Nm with a ±20% tolerance, and achieves ISO 14644-1 Class 4 cleanroom suitability alongside a CRC 1 corrosion resistance class.

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.
