Description
A small O-ring can make a big difference in your vacuum system. If your pump or chamber is not holding pressure, this little part is often the key. This Pfeiffer O-ring is designed to solve that problem.
We made this O-ring from Viton®. This is a special material known for its superpowers. It can handle high heat without losing its shape. It also stands up to aggressive oils and chemicals that ruin ordinary seals.
This means you get a seal that won’t let you down. It stays flexible and strong, even in tough conditions. This reliability helps your vacuum equipment work better for longer.
The size is 44 mm inside diameter with a 3 mm thickness. This is the exact size made for your Pfeiffer vacuum system. A perfect fit means no air leaks. No leaks mean strong, consistent vacuum pressure.
Using a feiffer part is always a good idea. It ensures everything works together smoothly. You protect your important equipment from wear and tear.
Replacing an old O-ring with this one is a simple task. But it has a huge impact. You will restore suction power and make your system more efficient.
