Product Information
Full details
The Plumbright Brass Hexagon Bush (BHB134) is an essential component for professional plumbers and DIY enthusiasts who need to bridge the gap between plumbing lines of different sizes. It provides a secure, leak-resistant transition between 1-inch and 3/4-inch pipes, ensuring long-term structural integrity in fluid transport systems. While this brass fitting is exceptionally durable and corrosion-resistant, users should ensure they apply appropriate thread-sealing tape or paste to prevent joint leaks under high pressure.

FAQs
Can I use this for gas lines?
This brass bush is designed for standard water plumbing; consult local building codes before using it for gas line applications.
Does this fitting need a washer?
This is a threaded fitting and typically relies on thread sealant (tape or paste) for the seal, not a washer.
What is the maximum pressure rating?
While brass is strong, the specific pressure rating depends on the pipe and the seal applied; always follow the guidelines for the piping system you are installing.
Is it safe for drinking water?
Yes, standard plumbing brass is generally suitable for potable water applications, though you should verify your local safety standards.
Can it be used outdoors?
Yes, brass is highly resistant to weather-related corrosion, making it suitable for outdoor pipe connections.
Troubleshooting
Joint is leaking after installation
Unscrew the fitting, clean off old sealant, apply fresh PTFE tape or pipe paste, and reinstall firmly.
Difficulty gripping the fitting during installation
Ensure you are using a properly sized wrench on the hex flats rather than gripping the round sections of the bush.
Threads feel tight or jammed
Check for cross-threading. If the threads are damaged, do not force them, as this will ruin the mating pipe.
Pros and Cons
Pros
- High-grade brass material resists rust and degradation
- Hexagon shape makes installation simple in tight spaces
- Provides a reliable, leak-proof reduction between pipe sizes
- Compatible with most standard pipe fittings
Cons
- Requires thread sealant for a guaranteed water-tight seal
- Limited to 1 to 3/4 inch size transitions
- Not suitable for high-acid environments where brass may react
Setup, Compatibility & Care
To install the bush, clean both male and female threads of any debris or old sealant. Apply a generous amount of PTFE tape or professional-grade pipe thread sealant to the threads before screwing the bush into place. Tighten until snug, using the hex profile to ensure the connection is firm. Avoid overtightening, as brass is a soft metal and threads can strip under extreme force. For care, keep the fitting dry and periodically check for signs of moisture or green oxidation, which may indicate a slow leak that needs re-sealing.
