Legris 3169 04 19 Extended Male Elbow Fitting M5x0.8

Product Description

The LEGRIS 3169 04 19 is a push-to-connect extended male elbow tube fitting designed for pneumatic and fluid control plumbing applications. It features a body constructed from glass-reinforced nylon with nickel-plated brass internal components and a nitrile O-ring seal. The fitting accepts a 4mm outside diameter tube and threads into an M5 x 0.8 male port. It is rated for a maximum working pressure of 290 psi and handles temperatures from -4 degrees F up to 290 degrees F, making it suitable for a wide range of industrial and mechanical system installations. Pneumatic technicians and mechanical contractors are the primary installers of this fitting type.

This fitting is used in pneumatic control systems, automation equipment, and fluid line assemblies where a 90-degree directional change is needed between a tube run and a threaded port. The extended elbow body provides additional clearance in tight panel or manifold installations. With a tube outside diameter of 4mm and an M5 x 0.8 thread, it is commonly found in instrumentation panels, solenoid valve manifolds, and light-duty pneumatic circuits in both commercial and industrial settings.

Key Features

• Push-to-connect design allows tool-free tube insertion and secure retention without ferrules or compression sleeves
• Glass-reinforced nylon body paired with nickel-plated brass internals for corrosion resistance and mechanical strength
• Nitrile O-ring seal provides reliable performance across a broad temperature and pressure range
• Rated to 290 psi maximum working pressure for demanding pneumatic service
• 28 in-Hg vacuum rating supports vacuum line applications in addition to pressure service
• Extended elbow geometry improves tube routing clearance in confined enclosures and panel layouts

Compatibility

Designed as an OEM-style push-to-connect fitting for pneumatic and fluid control systems using 4mm outside diameter tubing with M5 x 0.8 threaded ports.

Installation Notes

Installation is performed by mechanical technicians or pneumatic system technicians. Depressurize and isolate the system completely before removing or installing any fittings. Ensure the mating port threads are clean and undamaged before threading in the male end; follow the equipment manufacturer torque guidelines for M5 threaded ports. Insert tubing straight and fully into the push-to-connect collet until it seats, and confirm retention by pulling back firmly on the tube before repressurizing the circuit.
