Stern gland packing works as a flexible, braided seal that wraps around rotating shafts to control water flow for cooling and lubrication, while preventing unwanted leaks during steady operation. Our PTFE stern gland packing stands out with its pure PTFE fibers twisted into a soft, durable rope that adapts smoothly to shaft movement, offering low-friction performance and resistance to harsh conditions without the need for constant adjustments. Available in coils from 10mm to 30mm cross-sections and 10m lengths at a lightweight 1.5 g/cm³, this PTFE stern gland packing compresses evenly under moderate gland pressure, maintaining a consistent drip rate and temperature stability from -10°C to 80°C. Easy to cut and install with basic tools, it ensures reliable, long-term sealing with minimal maintenance, making it a practical choice for setups that demand clean, quiet, and lasting performance.
