SMC 10-KQ2VT04-01NS | Clean Room Metric One-Touch Fitting KQ2VT Series Triple Universal Male Elbow 4mm Tube x 1/8" NPT Sealant

The SMC 10-KQ2VT04-01NS is a clean room specification metric-size one-touch fitting from the KQ2VT series, configured as a triple universal male elbow. Part number decoded: KQ2VT = one-touch triple universal male elbow, 04 = 4mm tube OD (metric), 01 = 1/8" NPT male thread, N = factory-applied thread sealant, S = specific series confirmation. The triple universal elbow provides three-axis rotation capability, allowing the tube outlet to be positioned in virtually any direction after the fitting is threaded into the port.

What makes a "triple universal" elbow different from a standard elbow? A standard elbow provides a fixed 90-degree turn in one plane. The KQ2VT triple universal adds three independently rotating joints, enabling the tube exit direction to be adjusted in any orientation — critical in clean room equipment where tube routing must navigate complex internal geometries without kinking or interference. This eliminates the need to stock multiple elbow orientations and reduces installation time by allowing on-site directional adjustment.

The 4mm tube with 1/8" NPT is a compact configuration for small actuators, miniature valves, and pressure switches. Factory sealant (N) eliminates PTFE tape particles. For a standard fixed elbow at this size, the KQ2L04-01NS costs less but provides no rotational adjustment. For inch-size triple universal elbows, the KQ2VT series covers 1/8" through 1/2" tube sizes.
