The Thomas Dudley Nylon Back Nut is designed for both professional plumbers and DIY enthusiasts who need a reliable, durable component for securing plumbing fixtures. It provides a secure, leak-resistant fit for 3/4-inch BSP connections, offering excellent strength in a lightweight form factor. Users should note that while it is labeled as 3/4-inch, the physical diameter of a BSP thread measures 1 inch, so accurate measurement before purchase is essential to ensure compatibility.

You need a 31mm spanner.
No. In accordance with BSP standards, a 3/4-inch thread measures 1 inch in diameter.
Yes, the nylon material is resistant to corrosion, making it suitable for damp or outdoor plumbing areas.
Yes, as long as the pipe has a standard 3/4-inch BSP male thread.
The outside diameter of the nut is 42.5mm.
The nut is provided as a standalone component; always ensure you use an appropriate washer to create a watertight seal.
Ensure the washer is seated correctly between the nut and the basin/cistern surface before re-tightening.
Check threads for debris or paint; clean the male thread thoroughly before attempting to screw on the nut again.
To install, ensure the threads on your fixture are clean and free of debris. Always verify that your pipe thread is standard 3/4-inch BSP, which will measure 1 inch in outside diameter. Thread the nut by hand first to prevent cross-threading, then use a 31mm spanner to finish the job. Avoid using heavy-duty pipe wrenches that may grip and damage the nylon surface. To maintain the component, periodically check for signs of loosening due to thermal expansion or contraction and ensure no chemical cleaners are applied that might degrade the nylon material.
