Advantages:– Very good fitting stability avoiding pop-out of the seal– Modern lip design provides low radial forces– Superior radial stiffness, especially for very large diameters– Cost effective for expensive elastomer materials– Suitable for use in combination with axial seal
3. TEMPERATURE: Similar to the pressure level, you need to know what temperature your machinery can operate at. You need to choose a seal that can withstand the heat or cold. PTFE have the widest rang of temperature, making them a safe option when you are uncertain of the range.
