sourcing map Rubber Flat Washers 12mm OD 6mm ID 4.5mm Thickness for Faucet Pipe Water Hose, Pack of 20

Exactly what I needed; perfect fit and does it’s job well!!!!!

I needed to replace a disintegrated washer on the overflow pipe from my cistern. The cistern is over 20 years old, and I didn't think the pipe was a non-standard size, however the usual DIY places didn't have the correct size. These came quickly, fitted just right and solved my problem, leaving me with plenty of spares!

Useful addition to husbands tool box

I drove to Screwfix, a plumber's merchant and B&Q looking for a rubber washer this size. None could help me! Was a bit hesitant to order online as I wanted to check the exact size against the one I had already. Fortunately they fit. Now I have 19 spares! That's the problem with the old ironmongers having closed down.

I wanted a washer seal for a pressure washer, (Car/Patio etc). it's done the job, not much you can say about an item like this.

Used to seat a shower thermostat against shower plastic wall...worked fine.

these came up when i typed in for central heating pump valves.YES they described their measurements but i dont have a micrometer so assumed wrongly they were the same..DONT BE MISTAKEN LIKE ME

Very well made washers excelent quality
