The Thomas Dudley Tantofex Tap Washer is an essential plumbing component designed for homeowners and DIY enthusiasts looking to repair dripping 1/2 inch taps. This washer provides a reliable, long-lasting seal to stop leaks and restore smooth tap functionality. A crucial caveat for buyers is the sizing convention: while labeled as 1/2 inch, the washer is designed for a 1/2 inch BSP thread, meaning the physical diameter measures 3/4 inch (16.45mm).

The washer has an outer diameter of 16.45mm and a thickness of 5mm.
This is due to the BSP (British Standard Pipe) thread sizing convention, where the nominal thread size is typically 1/4 inch smaller than the actual diameter.
No, this washer is specifically designed for 1/2 inch BSP threaded taps and will not fit a 3/4 inch tap.
You generally only need a standard adjustable wrench or spanner to remove the tap head.
It is best to remove your existing washer and compare its diameter (16.45mm) to this product to confirm compatibility.
Ensure the tap bonnet is tightened sufficiently and check that the washer is correctly centered on the seat.
Verify that your tap is indeed a 1/2 inch BSP model. If the tap is a different size (such as 3/4 inch), this washer will not provide a seal.
To install this washer, follow these steps:
Note: Always verify your existing tap measurement. Remember that the 1/2 inch BSP specification refers to the thread standard, and the actual physical measurement of the washer is 16.45mm. Periodically check your taps for signs of wear to ensure longevity.
