Key features

Pressure Activated Sealing: Center sealing rings flare open under pressure to create a tight seal and minimize leakage.

Wear Compensation Design: System pressure expands sealing lips to compensate for wear until the packing is completely worn out.

No Tightening Required: Performs best when run loose (finger-tight) and requires no further tightening during operation.

Oil and Chemical Resistance: NBR and HNBR materials offer excellent resistance to oil, gasoline, and corrosive chemicals.

Customizable Materials: Available in NBR, HNBR, FKM, and PTFE with cotton fabric or Fabric reinforcement options.

Low Emissions Performance: Ideal for low emissions boxes and high-pressure applications in oil and gas industries.

ISO 9001 Certified: Manufacturing process adheres to ISO 9001:2015 standards for quality assurance.
