Festo
578402
Push-in T-fitting NPQH-T-G12-Q10-P10
The Festo 578402 is a standard T-shaped industrial component featuring an 8 mm nominal width, an 18.3 mm tubing insertion depth, and a sealing ring on the screwed plug for mounting in any position. Utilizing a push-pull structural design, it operates across a pressure range of -0.95 bar to 20 bar for compressed air and up to 0.6 MPa for water at 0 to 50 °C within an ambient temperature range of 0 °C to 150 °C. This pack size of 10 exhibits a Class 3 corrosion resistance, VDMA24364-B1/B2-L LABS conformity, ISO 14644-1 Class 4 cleanroom suitability, and NSF/ANSI 169 certification for the food industry under a 9 Nm nominal tightening torque with a ±20% tolerance.

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.
