Legris 3114 16 21 Push-to-connect Female Connector Fitting

Product Description

The LEGRIS 3114 16 21 is a straight push-to-connect female connector tube fitting designed for pneumatic and fluid-handling systems requiring a reliable tube-to-female BSPP thread connection. Constructed from nickel-plated brass with a nitrile O-ring seal, this fitting handles a maximum working pressure of 290 psi and a vacuum rating of 29 in-Hg. The 16mm tube outside diameter inlet accepts standard metric tubing with a simple push-in connection, while the 1/2 inch BSPP female thread port mates to standard British Standard Parallel Pipe fittings. Licensed trades and industrial maintenance technicians install this fitting where quick, repeatable connections are required in pneumatic circuits.

This fitting is suited for use in pneumatic systems, packaging machinery, robotics, and textile industrial equipment. The combination of metric tube compatibility and BSPP female thread makes it a practical interface between metric tubing runs and BSPP-ported valves, cylinders, or manifolds. With an overall length of approximately 49mm and a compact 16mm tube diameter, it fits in tight panel or manifold installations. It meets multiple international compliance standards including ISO 14743, PED 97/23/EC, RoHS, and REACH, making it appropriate for regulated industrial and OEM applications.

Key Features

• Push-to-connect inlet accepts 16mm outside diameter metric tubing without tools
• 1/2 inch BSPP female thread port for direct connection to BSPP-ported components
• Nickel-plated brass body resists corrosion in pneumatic and light fluid service
• Nitrile O-ring seal rated for vacuum service up to 29 in-Hg and pressure up to 290 psi
• Compliant with ISO 14743, RoHS, REACH, and PED 97/23/EC standards
• Compact straight profile suitable for packaging, robotics, and textile industrial applications

Compatibility

Designed for use in pneumatic, packaging, robotics, and textile industrial systems that require a 16mm metric tube push-to-connect inlet with a 1/2 inch BSPP female thread outlet. Compatible with standard 16mm outside diameter metric tubing runs.

Installation Notes

Installation is performed by licensed pipefitters, pneumatic system technicians, or qualified industrial maintenance personnel. Depressurize and lock out the pneumatic or fluid circuit completely before removing or installing any fitting. Ensure the tubing end is cut cleanly and squarely and is free of burrs before inserting into the push-to-connect collet. Verify that BSPP thread engagement is appropriate and that mating port threads are clean and undamaged before torquing the connection.
