Industrial-Grade Ramie Fiber Gland Packing Seal‌

Ramie gland packing is a ‌braided sealing material‌ made from ‌ramie fibers‌ (derived from the Boehmeria nivea plant), used to prevent fluid leakage in ‌rotating or reciprocating shafts‌ (e.g., valves, pumps, and mixers). It acts as a ‌flexible, compressible barrier‌ between the shaft and gland housing, absorbing vibrations and maintaining a seal under low-to-moderate pressure.

Ramie gland packing is a braided sealing material made from ramie plant fibers (Boehmeria nivea), used to prevent leaks in rotating or reciprocating shafts (e.g., valves, pumps). It excels in ‌low-pressure, low-speed applications‌ (up to ‌10 bar‌, ‌120°C‌) due to its natural ‌flexibility, low friction, and biodegradability‌. Ideal for water, steam, and weak chemicals, it’s an ‌eco-friendly alternative‌ to asbestos or synthetic packings.

‌Key features‌:

‌Thermal Resistance‌: Stable from -40°C to 120°C.
‌Chemical Compatibility‌: Resists water, oils, and mild acids/alkalis.
‌Cost-Effective‌: Affordable for agricultural, municipal, or vintage machinery.
‌Limitations‌: Not suitable for high-pressure/high-speed systems or harsh chemicals. Variants like ‌graphite-impregnated‌ or ‌PTFE-coated ramie‌ enhance performance. Requires periodic tightening for optimal sealing
