Compression fitting AGAflex for bare end of steel pipe, blue PE sleeve, male thread G 3/8"

AGAflex compression fitting for a bare end of steel pipe provides a mechanical, leak-resistant connection point with a blue polyethylene (PE) sleeve and an external G 3/8" male thread. The fitting is intended for plumbing and heating installations where a reliable transition from a steel pipe to threaded components is required. Its design allows a direct attachment to pipes without insulation and is compatible with standard G 3/8" threaded valves and accessories.

Advantages

The blue PE sleeve protects the pipe end, reduces corrosion risk at the connection point and aids visual identification. The compression mechanism creates a secure seal on bare steel pipe without the need for welding or soldering. The G 3/8" male thread offers wide compatibility with common valves and fittings, enabling quick installation and straightforward maintenance.

Suitable for

• Plumbing installations requiring a threaded transition from a steel pipe
• Heating systems where a secure mechanical connection to bare steel pipe is needed
• Repair work and retrofits when welding or brazing is impractical
• Connections to valves, gauges or service points with G 3/8" female threads

Key specifications

• Connection type: compression fitting for bare (uninsulated) steel pipe
• Sleeve material and color: polyethylene (PE), blue
• Thread: external male G 3/8"
• Application: plumbing and heating systems
• Seal type: mechanical compression seal (no soldering required)

How to use

Prepare the bare steel pipe end by cutting it square and removing burrs to ensure a smooth surface. Slide the fitting onto the pipe and position the PE sleeve so it covers the pipe end. Tighten the compression nut to the specified torque, following manufacturer guidance or standard plumbing practice, until the mechanical seal is formed. Then attach the G 3/8" female-threaded component and verify joint tightness and absence of leaks under working pressure.

Usage recommendations

Use appropriate tools to achieve correct torque and avoid over-tightening, which can damage the sleeve or deform the pipe. Inspect the steel pipe for corrosion or damage before installation and replace pipe sections that are compromised. After installation, perform a pressure test according to local codes to confirm leak-free operation.
