EPTFE valve stem packing is a pure, self-forming sealing material with high tensile strength. It deforms under compression to fill surface imperfections, offering excellent sealing and wear resistance.

1. Features

Chemical Resistance: Inert to most chemicals (pH 0–14), no fillers or binders.
Temperature Range: Stable from -158°C to +260°C.
Self-Lubricating: Reduces friction, prevents stem wear.
High Pressure Tolerance: Withstands up to 20 MPa (2900 psi).
Clean and Non-Contaminating: Suitable for sensitive applications like food and pharmaceuticals.

2. Advantages

Easy Installation: Continuous-length form, no cutting or special tools needed.
Reduced Inventory: Single packing fits multiple applications.
Durability: No age deterioration, long service life.
Minimal Maintenance: Reduces costly repairs and replacements.
