Legris 3603 04 11 Push-to-connect Tube Fitting Npt

Product Description

The LEGRIS 3603 04 11 is a push-to-connect tube fitting designed for inline connections between tubing runs and male NPT ports. The fitting accepts 5/32 inch OD tubing on both tube ends and features a 1/8 inch male NPT thread at center, creating a tube-to-MNPT-to-tube configuration in a single compact body. Constructed from nickel-plated brass, it is rated for a maximum working pressure of 435 psi and handles both liquid and gas service. FKM o-rings provide a reliable seal across a wide temperature range. Plumbers, pipefitters, and pneumatic system technicians install this fitting in instrumentation, compressed air, and fluid control applications.

This fitting is suited for residential and light commercial applications wherever 5/32 inch OD tubing must transition to or from a 1/8 inch NPT male threaded port. It supports both liquid and gas media, making it appropriate for compressed air lines, pneumatic control circuits, hydraulic instrumentation tubing, and similar low-to-medium pressure plumbing assemblies. The push-to-connect design allows fast, tool-free tube insertion while maintaining a pressure-rated seal without the need for compression ferrules or separate fittings at the tube ends.

Key Features

• Push-to-connect tube ends accept 5/32 inch OD tubing without tools or ferrules
• 1/8 inch male NPT center thread connects directly to standard NPT female ports
• Nickel-plated brass construction resists corrosion in wet and humid environments
• Rated to 435 psi maximum working pressure for reliable service in pressurized systems
• FKM o-rings compatible with a broad range of liquids and gases
• Operating temperature range of -4 degrees F to 302 degrees F

Compatibility

Designed for use with liquid and gas service lines utilizing 5/32 inch OD tubing and 1/8 inch NPT threaded ports. Suitable as an OEM-style replacement or new-installation fitting in pneumatic control and fluid instrumentation assemblies.

Installation Notes

Installation is performed by plumbers, pipefitters, or pneumatic system technicians familiar with pressurized tubing systems. Depressurize and drain the line completely before removing or installing any fitting. Apply thread sealant or PTFE tape to the male NPT threads in accordance with applicable plumbing codes before making up the threaded connection. Verify that tubing OD is within the manufacturer-specified tolerance before seating into the push-to-connect ends to ensure a proper seal.
