Soft packing seals are flexible sealing elements that close the gap between shaft and housing to provide leakage prevention and mechanical isolation. They are widely used in pipeline systems, pumps, valves, rotor shaft connections, and industrial mechanisms to prevent water, oil, fuel, and fluid leakage.
Flowland soft packing seals are available in PTFE, SAF Graphite, Aramid, and Zebra material types — offering long-lasting performance with excellent chemical compatibility and flexible surface adaptation.

Frequently Asked Questions
A soft packing seal is a flexible sealing element that fills the gap between a rotating or reciprocating shaft and its housing. It prevents fluid or gas leakage while allowing shaft movement, and is widely used in pumps, valves, and industrial rotating equipment.
Flowland soft packing seals are available in PTFE, SAF Graphite, Aramid, and Zebra composite materials. Each material is selected based on the application's fluid type, temperature, pressure, and chemical compatibility requirements.
They are used in industrial pump shafts, valve stems, rotor connections, pipeline process circuits, marine engine rooms, mechanical systems, and pressurised system connections — wherever a flexible, reliable shaft seal is required.
Flowland soft packing seals are rated for operating temperatures between -40°C and +120°C depending on the material selected. PTFE-based variants offer the widest chemical compatibility, while graphite variants provide enhanced performance at higher temperatures.
Flowland soft packing seals are available in split, single-piece, and double-piece configurations. Split types allow installation without removing the shaft, making them ideal for maintenance applications where downtime must be minimised.
