Pilotgraph 4001 Packing
- Long sealing life for high temperature high pressure applications
- Inclusion of a corrosion inhibitor ensures stainless steel shafts do not suffer pitting
- Manufactured from highest quality pure graphite with minimal impurities
- High thermal conductivity and low friction properties ensure increased service life
- Easy to cut and install so can be used to replace moulded rings resulting in greatly reduced stock and cost
Reciprocating Applications
Speed: 2 m/s (390 fpm)
Temperature range: -200 to +450°C (-330 to +840°F)
Maximum pressure: 200 Bar (3900 psi)
Chemical Compatibilities
For the pH range 0–14, the packing is chemically inert and suitable for steam. It should not be installed in strong oxidising environments such as hot concentrated nitric acid, highly concentrated sulphuric acid and molten alkali metals.
