Product Information

Full details

The Young Wolf 4-Way Cross Union Pipe Fitting is designed for professionals and DIY enthusiasts requiring a reliable multi-directional connection for 15mm pipework in HVAC, refrigeration, and plumbing systems. It offers excellent thermal conductivity and durability against high pressure and corrosion, making it a robust choice for complex piping layouts. Please note that these fittings require proper soldering or mechanical joining techniques for a leak-free seal, as they do not feature self-locking mechanisms.

FAQs

Can I use this fitting for gas lines?

This fitting is designed for water and hydraulic cooling systems. Always check local building codes and safety regulations before using any fitting in gas distribution.

Is the 15mm size inner or outer diameter?

The fitting features a 15mm inner diameter to accommodate 15mm outer diameter standard piping.

Does this product come with gaskets or O-rings?

No, this is a metal union fitting designed for soldered or compression-style joints, not rubber-gasket sealing.

What is the wall thickness of the fitting?

The fitting has a consistent 1mm wall thickness for structural strength.

Can I use this fitting for drinking water?

Yes, provided the installation material and joining method meet regional drinking water safety standards.

Troubleshooting

Joint appears to leak after installation.

Ensure the pipe was fully cleaned of all debris and oxidation before joining. Re-heat and re-apply solder if a gap is visible.

Fitting is too tight to slide onto the pipe.

Check the pipe end for burrs or deformation from cutting. Ensure the pipe is not 'out of round' and file the edge slightly if necessary.

Pros and Cons

Pros

  • Uniform wall thickness ensures consistent pressure distribution.
  • Compact 47 x 47mm footprint saves space in tight installations.
  • High resistance to temperature fluctuations for reliable performance.
  • Multipurpose utility across plumbing and HVAC sectors.

Cons

  • Requires professional joining equipment such as a soldering torch.
  • Not intended for non-standard pipe sizes exceeding 15mm.
  • Lack of pre-applied sealant necessitates the use of high-quality flux or jointing compound.

Setup, Compatibility & Care

  1. Preparation: Clean the ends of your 15mm pipes using abrasive cloth to remove oxidation.
  2. Compatibility: Ensure the pipes being joined are standard 15mm diameter copper or metal alloy. Do not use with flexible plastic piping unless using appropriate internal stiffeners and compatible adapters.
  3. Joining: Apply suitable flux to the pipe ends and the interior of the fitting. Use appropriate soldering techniques. Avoid overheating the fitting, which can warp the material.
  4. Maintenance: Regularly inspect joints for signs of 'weeping' or corrosion. In high-vibration environments, ensure pipes are adequately supported by brackets to prevent mechanical stress on the 4-way union.
