Selection Guide
1. Highly Corrosive Conditions: Choose pure PTFE standard type.
2. High Load Conditions: Recommend glass fiber reinforced type (PTFE + 20% fiberglass).
3. Precise Separation: Smaller sizes (DN16/DN25) are superior.
4. Energy-saving Retrofit: Recommended to replace existing ceramic/metal packing.
