Festo 130831 QSMLV-M5-4-I – Push-In L-Fitting, Mini Series, M5 Male Thread to 4 mm Tubing
The Festo 130831 (type QSMLV-M5-4-I) is a push-in L-fitting from Festo’s QS mini series. It connects 4 mm OD pneumatic tubing at 90° to an M5 threaded port, which makes it one of the most common fittings for miniature valves, small cylinders, grippers and vacuum components where space is tight.
The fitting has an M5 external thread with internal hexagon and seals on the screw-in stud with a sealing ring. The housing is PBT, the tube clamping is stainless steel and the tube seal is NBR. The tube side uses the push-pull principle with a blue release ring. The fitting handles vacuum down to −0.95 bar and pressures up to 6 bar across the full temperature range, or up to 14 bar depending on temperature.
