PTFE Gland Packing | Chemical-Resistant Pump & Valve Packing

Kaybin supplies PTFE gland packing for pumps, valves and rotating equipment used in chemical, process, water treatment and industrial applications across South Africa and Africa. PTFE packing is selected where chemical resistance, low friction and clean sealing performance are more important than high-temperature steam capability or abrasive-duty strength.

Material & Duty

This material family includes virgin, lubricated and graphite-filled PTFE grades for corrosive media, general chemical service and low-friction pump and valve applications. PTFE is commonly specified where graphite or aramid are not the primary fit and where media compatibility is critical to sealing performance.

Typical Applications

• Chemical process pumps
• Corrosive valve service
• Water treatment systems
• General industrial pump and valve applications
• Low-friction rotating equipment sealing

Performance Considerations

Performance depends on operating temperature, pressure, shaft speed, media conditions and stuffing box clearance. PTFE offers broad chemical resistance and low friction, but correct selection must account for cold flow and extrusion risk under sustained compression or higher differential pressure.

Common Service Issues Addressed

• Leakage in corrosive media
• Friction-related wear in pump and valve duty
• Compression loss from cold flow
• Extrusion under pressure
• Reduced packing life from incorrect media selection

Supply

Available in various metric sizes and supplied by the box or per kilogram.

Selection Requirements

Correct specification is based on:

• Shaft diameter
• Stuffing box dimensions
• Operating pressure
• Operating temperature
• Shaft speed
• Media compatibility
• Clearance conditions
