Hey DIYers and repair folks, these PTFE washers are seriously handy to have around the workshop. Made from polytetrafluoroethylene (that's Teflon for us normal people), these little white rings are basically indestructible when it comes to chemical resistance. They can handle pretty much any corrosive substance you throw at them, plus they've got that famous non-stick surface that prevents stuff from bonding to them. The dimensions are 45mm outer diameter with a 35mm inner hole and 2mm thickness - perfect for all sorts of plumbing, automotive, or industrial applications. What's cool about PTFE is it maintains its properties across a huge temperature range, so whether you're dealing with freezing cold or pretty high heat, these washers won't let you down. They're great for distributing load under fasteners, working as spacers, or creating solid seals in piping systems. The pack comes with 10 pieces, which is enough for multiple projects or to have spares on hand. I've used them in everything from fixing leaky pipes to customizing equipment where chemical resistance matters. The white color makes them easy to identify in your parts collection too. Shipping does take a bit since they come from China, but the quality is solid for the price. If you need reliable, chemical-resistant washers that won't degrade over time, this PTFE set is definitely worth adding to your toolkit.
