Legris 3129 04 13 Extended Male Elbow Ptc Fitting 4mm

Product Description

The LEGRIS 3129 04 13 is a push-to-connect extended male elbow tube fitting designed for pneumatic and fluid plumbing systems where a 90-degree directional change is needed at a male-threaded port. Built with a nylon body and nickel-plated brass components, this fitting accepts a 4mm outside diameter tube and connects to a 1/4 inch BSPP male thread. It is rated to 290 psi and is well-suited for compressed air, light pneumatic control circuits, and instrumentation lines. Plumbers, pipefitters, and pneumatic system technicians are the typical installers in both industrial and commercial settings.

This fitting is used in pneumatic control panels, fluid distribution manifolds, and instrumentation tubing runs where a compact, tool-free tube connection at a male-threaded port is required. The extended elbow geometry provides clearance in tight panel layouts or where a standard elbow would conflict with adjacent components. It is appropriate for use in light industrial, commercial HVAC controls, and process instrumentation applications where 4mm OD tubing terminates at a BSPP-threaded port.

Key Features

• Push-to-connect design allows tool-free tube insertion and quick disconnection
• Extended elbow geometry provides clearance in tight or congested installations
• Nylon body with nickel-plated brass internals for corrosion resistance and durability
• Rated to 290 psi for use in compressed air and light fluid systems
• Accepts 4mm outside diameter tubing with a 1/4 inch BSPP male thread connection

Compatibility

Designed for use with 4mm OD tubing systems terminating at 1/4 inch BSPP male-threaded ports. Suitable for compressed air, pneumatic control, and instrumentation plumbing circuits using metric tubing.

Installation Notes

Installation is performed by plumbers, pipefitters, or pneumatic system technicians. Before servicing or replacing any fitting, depressurize and isolate the line completely. Ensure the tube end is cut cleanly and squarely with no burrs before insertion into the push-to-connect collet. Verify thread compatibility before engagement, as BSPP is a parallel thread and may require a sealing compound or bonded seal washer to achieve a leak-free joint at the port face.
