Smc Pneumatics M-01AN-4 Mini Barb Elbow M5x1

Product Description

The SMC PNEUMATICS M-01AN-4 is a mini barb elbow fitting designed for small-bore pneumatic tubing connections in compact plumbing and air-line assemblies. This 90-degree elbow accepts tubing with a 2.5 mm inside diameter and 4 mm outside diameter, threaded at M5 x 1 for direct connection to M5-ported components such as solenoid valves, cylinders, and manifold bodies. Constructed from steel, it provides reliable mechanical retention at the barb and a secure threaded engagement at the port end. The fitting is sold individually, with a minimum order quantity of 5 units.

This fitting is used in light pneumatic circuits where space is limited and a directional change in tubing routing is required. Common applications include machine automation panels, pneumatic control circuits, and instrumentation assemblies that use M5-ported components with 4 mm OD soft tubing. It is typically installed by maintenance technicians, machine builders, and instrumentation technicians working with compact pneumatic systems.

Key Features

• 90-degree elbow configuration for space-constrained routing
• M5 x 1 threaded port for direct fitment to M5-ported valves and cylinders
• Accepts 2.5 mm ID / 4 mm OD pneumatic tubing
• Steel construction for mechanical durability at the barb and thread interface
• Compact mini-barb design suited for low-profile pneumatic assemblies

Compatibility

Designed as an OEM-style fitting for pneumatic systems using M5 x 1 threaded ports and 4 mm OD small-bore tubing.

Installation Notes

Installation is performed by qualified technicians working on pneumatic control systems. Depressurize and lock out the pneumatic circuit before removing or installing any fittings. Thread the M5 x 1 end into the ported component by hand first to avoid cross-threading, and apply appropriate thread sealant or PTFE tape as required by the system design. Ensure the tubing is fully seated over the barb and that the system is leak-tested before returning it to service.
