This conversion set delivers a secure, watertight connection for water supply networks without requiring specialized installation tools, though users must carefully verify thread dimensions to avoid common sizing pitfalls related to BSP measurements.

The fittings are approved to BS1972/76 standards for durability and safety in water distribution.
Measure the outer diameter of the male thread. If it measures 1 inch, choose the 3/4 inch BSP version; if it measures 3/4 inch, choose the 1/2 inch version.
Ensure the pipe end is clean and cut perfectly square; re-check the thread sizing as the fitting might be loose due to incorrect nominal size selection.
Verify that you are using the correct thread size. Remember that a 3/4 inch BSP thread measures 1 inch; if your measurement is 3/4 inch, you need the 1/2 inch adapter.
To ensure a successful setup, always measure your existing threaded connections precisely. Note that BSP thread dimensions measure approximately 1/4 inch larger than their nominal size. Consequently, this 3/4 inch BSP thread will measure roughly 1 inch in actual diameter. If your current pipe thread measures exactly 3/4 inch, you likely need the 1/2 inch version of this product.
Installation steps:
For care, periodically inspect joints for moisture, though properly installed Plasson fittings are designed to remain maintenance-free for the lifespan of the pipe connection.
