Festo Instant Male Elbow QSML-4-M5

Official Festo type reference: QSML-M5-4 (Festo QSM mini-series push-in L-fitting; Part No. 153333)

The Festo Instant Male Elbow QSML-4-M5 is a compact 90-degree pneumatic L-fitting that connects 4 mm outside-diameter tubing to an M5 male threaded port. Its right-angle geometry is useful where tubing needs to turn immediately at the component connection, helping reduce routing space in compact pneumatic assemblies. The current Festo type designation is QSML-M5-4; this listing uses the commonly presented 4-M5 naming.
