Legris 3699 56 10 Male Elbow Ptc Fitting 1/4 Od Bspp

Product Description

The LEGRIS 3699 56 10 is a push-to-connect male elbow tube fitting designed for quick, tool-free tube connections in fluid and gas distribution systems. Constructed from nickel-plated brass with an FKM O-ring, it accepts 1/4-inch OD tubing on both tube ports and connects to a 1/8-inch BSPP male thread. The fitting is rated to 435 psi maximum working pressure and handles temperatures from -4 degrees F to 302 degrees F, making it suitable for a wide range of compressed air, pneumatic, and liquid-handling applications. Plumbing and industrial service technicians install this fitting where a 90-degree direction change is needed in a tube run.

This fitting is used in residential and commercial pneumatic control systems, fluid power circuits, and instrumentation lines that carry liquid or gas media. The push-to-connect design allows fast field assembly without compression tools or thread tape on the tube side, reducing installation time on equipment panels, valve manifolds, and inline pneumatic controls. The BSPP male thread end connects to standard BSPP-ported valves, gauges, or manifold blocks.

Installation Notes

Installation is performed by plumbers, pipefitters, or pneumatic system technicians. Depressurize and isolate the system completely before removing or installing any tube fittings. Ensure tubing is cut square and deburred before inserting into the push-to-connect port to achieve a proper seal. The BSPP threaded end requires a compatible BSPP female port and an appropriate thread sealant or sealing washer per the system requirements and applicable codes.
