Full details
The Plumbright Brass Hexagon Bush (1/4 x 1/8 inch) is an essential plumbing component designed for DIY enthusiasts and professionals seeking a secure, long-lasting reduction in pipe diameter. It excels at creating reliable, leak-free connections in tight spaces thanks to its robust brass construction and compact design, though users should ensure they have the correct thread sealant on hand to prevent potential seepage under high-pressure conditions.

FAQs
What does the 1/4 x 1/8 inch specification mean?
This means the external thread on the bush is 1/4 inch, and the internal threaded port is 1/8 inch.
Is this fitting suitable for high-pressure systems?
Yes, brass bushings are rated for high-pressure plumbing applications, provided the joint is correctly sealed.
Do I need to use thread sealant?
It is highly recommended to use PTFE tape or a compatible thread compound to ensure a watertight or airtight seal.
Can this be used with plastic pipes?
It is intended for use with metal plumbing systems. Using it directly on soft plastic threads may cause damage to the plastic.
Is this bush corrosion-resistant?
Yes, the brass construction is naturally resistant to rust and corrosion in standard plumbing environments.
Troubleshooting
The fitting is leaking at the thread.
Ensure sufficient PTFE tape was applied and that the fitting is tightened adequately, but not forced beyond its natural stop point.
Difficulty in threading the bush into the port.
Verify that the thread types (NPT vs BSP) are compatible. If the threads are misaligned, back the fitting out completely and restart to prevent cross-threading.
Pros and Cons

Setup, Compatibility & Care
To install, ensure the threads on both the 1/4 inch female port and the 1/8 inch male pipe are clean and free of debris. Apply high-quality PTFE thread-sealing tape to the male threads, ensuring you wrap in the direction of the thread. Screw the bush into the 1/4 inch port using an appropriate wrench, then thread your 1/8 inch component into the bush. Avoid over-tightening, as brass is a soft metal and threads can deform. For long-term care, periodically check the connection for signs of moisture or air leaks. Brass is resistant to most common plumbing environments but should be protected from harsh acidic cleaners.
