FAQs

What is the primary function of a hexagonal bush?

A hexagonal bush is used to join two pipes or fittings of different sizes together while providing a hexagonal exterior for easy tightening.

Can I use this for gas lines?

This product is designed for general plumbing applications. Always verify local safety regulations and compatibility before using on gas lines.

Do I need special tools to install this?

No, you only need standard tools like an adjustable wrench or a pipe spanner.

Is the finish safe for drinking water systems?

Yes, the Primaflow fitting is suitable for use in standard domestic water supply systems.

Should I use pipe paste or tape?

Both PTFE tape and high-quality plumbing pipe sealant are effective for creating a seal with this fitting.

Will this rust over time?

The component features a corrosion-resistant finish designed to withstand moisture and prevent rust in typical plumbing environments.

Troubleshooting

Joint is leaking after installation

Unscrew the fitting, inspect the threads for damage, reapply a generous layer of PTFE tape, and retighten.

Difficulty gripping the fitting

Ensure the jaw of your wrench is set to the correct width for the hexagonal flats and that you are not trying to grip the rounded sections.

Fitting will not thread on

Verify that you are not cross-threading and confirm the threads on your existing pipe match the standard BSP threading of the bush.

Pros and Cons

Pros

  • Easy to tighten with standard tools
  • Corrosion-resistant for long-term reliability
  • Sturdy design prevents leaks when installed correctly
  • Suitable for a wide variety of plumbing applications

Cons

  • Requires proper thread sealing to guarantee a leak-free joint
  • Specific 2" to 1" size is not adjustable for other diameters
  • Must verify thread compatibility with existing pipework

Setup, Compatibility & Care

To install, ensure the threads on both the 2-inch and 1-inch connections are clean and free of debris. Apply an appropriate amount of PTFE tape or liquid pipe sealant to the male threads to ensure a water-tight seal. Tighten the bush using an adjustable wrench until firm, taking care not to over-torque, which can stress the pipe threads. For maintenance, periodically inspect the joint for signs of dampness or mineral buildup. The corrosion-resistant finish typically requires no special care, but wiping the exterior with a dry cloth during annual check-ups will keep the fitting in pristine condition.
