NA 802SR

New generation packing of homogenous graphited PTFE yarns reinforced with aramid fibre in each yarn with special hollow silicon rubber core pre-lubricated in interlock braid

  • Excellent chemical resistance, heat dissipating, sliding velocity, low co-efficient of friction properties of PTFE graphite and the abrasion, pressure/ extrusion resistance and mechanical strength of aramid
  • High quality silicon rubber hollow core provides superb memory and resilience, enabling the packing to withstand shaft deflections/vibrations with ease
  • NA 802SR is a soft supple packing, non-abrasive in nature and gentle on the shaft

Ideal for aggressive chemical fluids operating at high pressures and shaft speeds
