Product Information

Full details

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).

Extended Product Information

FAQs

What are the exact dimensions of this washer?

The washer has an outer diameter of 16.45mm and a thickness of 5mm.

Why is it labeled 1/2 inch if it measures 3/4 inch?

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.

Can I use this for a 3/4 inch tap?

No, this washer is specifically designed for 1/2 inch BSP threaded taps and will not fit a 3/4 inch tap.

Do I need special tools to install this?

You generally only need a standard adjustable wrench or spanner to remove the tap head.

How do I know if this is the right replacement for my tap?

It is best to remove your existing washer and compare its diameter (16.45mm) to this product to confirm compatibility.

Troubleshooting

Tap continues to drip after installation

Ensure the tap bonnet is tightened sufficiently and check that the washer is correctly centered on the seat.

Washer seems too small for the housing

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.

Pros and Cons

Pros

  • Cost-effective solution for fixing leaking taps
  • Easy to install for DIY home repairs
  • High-quality construction for a long-lasting seal
  • Compatible with a wide range of standard 1/2 inch tap models

Cons

  • Confusing sizing due to BSP measurement standards
  • Requires disassembly of the tap to verify sizing
  • Not suitable for non-standard or proprietary tap mechanisms

Setup, Compatibility & Care

To install this washer, follow these steps:

  1. Isolate the water supply to the tap.
  2. Open the tap to drain any remaining water.
  3. Unscrew the tap head or bonnet using an adjustable wrench.
  4. Remove the old washer from the jumper valve or spindle.
  5. Insert the new Thomas Dudley Tantofex washer, ensuring it is seated perfectly flat.
  6. Reassemble the tap components and tighten the bonnet firmly, but avoid over-tightening which can damage the new seal.

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.
