Legris 3601 04 13 Push-to-connect Male Connector Fitting

Product Description

The LEGRIS 3601 04 13 is a push-to-connect male connector tube fitting designed for fast, tool-free tube connections in fluid and pneumatic systems. Constructed from nickel-plated brass, it accepts 4mm outside diameter tubing on the tube end and terminates in a 1/4 inch BSPP male thread on the opposite end. Rated to 435 psi maximum working pressure, this fitting handles both liquid and gas service across a temperature range of -4 degrees F to 302 degrees F. The FKM o-ring provides reliable sealing compatibility with a broad range of media. Licensed HVAC, plumbing, and industrial piping technicians install this fitting in compressed air, pneumatic control, and fluid transfer lines.

This fitting suits residential and light commercial pneumatic and fluid handling applications where a quick push-to-connect interface is required. The tube-to-male configuration allows direct connection between a 4mm OD tube and a BSPP-threaded port, such as a valve, manifold, or instrument body. It is compliant with multiple international standards including RoHS, ATEX, PED, REACH, ISO 14743, and FDA 21CFR, making it appropriate for use in regulated environments handling liquid and gas media.

Key Features

• Push-to-connect design allows fast, tool-free tube insertion without ferrules or compression rings
• Nickel-plated brass construction resists corrosion in liquid and gas service
• 435 psi maximum working pressure rating
• 4mm OD tube connection with 1/4 inch BSPP male thread
• FKM o-ring sealing for broad media compatibility
• Compliant with RoHS, ATEX, PED, REACH, ISO 14743, UL94 V-0, and FDA 21CFR

Compatibility

Designed for use with 4mm outside diameter tubing in liquid and gas service applications. Suitable for pneumatic control systems, compressed air lines, and fluid transfer circuits using BSPP-threaded ports.

Installation Notes

Installation is performed by licensed plumbing, HVAC, or industrial piping technicians. Depressurize and isolate the line fully before removing or installing any fitting. Ensure the BSPP male thread is wrapped with appropriate thread sealant tape or compound compatible with the service media before threading into the port. Verify that the tube outside diameter is exactly 4mm and cut is clean and square before pushing into the collet to achieve a proper seal.
