Festo
133191
Push-in fitting QS-1/8-4-I-100
The Festo 133191 is a straight industrial component featuring a push-pull structural design with a nominal width of 2.6 mm and a 14.9 mm tubing insertion depth. It includes an external thread R1/8 pneumatic connection 1 and accommodates a 4 mm outside diameter pneumatic tubing connection 2, utilizing a coated screwed plug seal and an internal hex AF2.5 mounting type. This part operates across an ambient temperature range of -10 °C to 80 °C with compressed air or liquid water, supporting an operating pressure of -0.095 MPa to 0.6 MPa for the entire temperature range and up to 1.4 MPa in temperature-dependent conditions. Available in a pack size of 100 with a product weight of 6.6 g each, it achieves ISO 14644-1 Class 4 cleanroom suitability and a low corrosion stress CRC of 1.

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.
