Key Features & Advantages of PTFE V Packing Seals
Pressure-Activated Sealing Design
V-shaped lips expand under pressure to enhance sealing performance
Excellent sealing efficiency across a wide pressure range
Suitable for fluctuating and intermittent pressure conditions
Outstanding Chemical Resistance
PTFE material provides near-universal chemical compatibility
Resistant to:
Acids and alkalis
Solvents and aggressive chemicals
Oils, fuels, and hydraulic fluids
Low Friction & Smooth Operation
Low coefficient of friction reduces stick-slip effects
Ideal for hydraulic cylinders and reciprocating motion
Minimizes wear on rods and shafts
Modular & Adjustable Structure
Sealing force can be adjusted by changing the number of V-rings
Easy installation and maintenance
Allows compensation for wear during service
Why Choose PTFE V Packing Seals?
Reliable sealing under high pressure and aggressive media
Longer service life compared to rubber packing seals
Flexible design adaptable to various operating conditions
Reduced maintenance and downtime
