Legris 3129 04 10 Extended Male Elbow 4mm 1/8 Bspt

Product Description

The LEGRIS 3129 04 10 is a push-to-connect extended male elbow tube fitting designed for pneumatic and fluid control plumbing applications. It connects 4mm outside diameter tubing to a 1/8 inch male BSPT threaded port in a 90-degree elbow configuration. The extended male thread design provides additional reach in tight installations. The fitting body is constructed from nylon and nickel-plated brass, offering corrosion resistance and reliable sealing under working pressures up to 290 psi. This type of fitting is typically installed by pneumatic system technicians, instrumentation mechanics, and industrial plumbers working on compressed air lines, fluid control manifolds, and automation equipment.

This fitting is suited for light industrial and commercial pneumatic systems where 4mm OD tubing terminates at a male BSPT threaded port. Common install scenarios include connecting tubing runs to solenoid valve bodies, manifold blocks, cylinders, and instrument ports. The push-to-connect design allows for tool-free tube insertion and provides a secure, leak-resistant connection rated for repeated connect and disconnect cycles. It is well-suited for dry air, inert gas, and compatible fluid service within its rated pressure range.

Key Features

• Push-to-connect design allows tool-free tube insertion for fast assembly and field service
• Extended male elbow configuration provides reach in confined or offset port locations
• Rated to 290 psi working pressure for reliable performance on compressed air and fluid lines
• Nylon and nickel-plated brass construction resists corrosion in industrial environments
• Compatible with 4mm outside diameter tubing for precise, leak-resistant termination
• 1/8 inch BSPT male thread for direct installation into standard metric-threaded ports

Compatibility

Designed as an OEM-style push-to-connect fitting for pneumatic and fluid systems using 4mm OD tubing and 1/8 inch BSPT male threaded ports. No specific compatible model numbers are identified in the available product data.

Installation Notes

Installation is typically performed by instrumentation technicians or industrial plumbers. De-pressurize and lock out the pneumatic or fluid circuit completely before removing or installing any fittings. Ensure the receiving port thread is clean and undamaged before threading in the male BSPT connection; apply thread sealant appropriate for the service fluid and in accordance with applicable plumbing codes. Insert tubing fully into the push-to-connect collet until it seats, and verify retention by pulling back lightly on the tube before re-pressurizing the system.
