8510 product is a gland packing made by braiding MacFoil (Expanded Graphite) yarn into a sectionally square shape.
Since we do not reinforce metal wire like ordinary expanded graphite type gland packing, it is possible to drastically suppress shaft wear.

Moreover, it can be used under high temperature, high circumferential speed condition from the characteristics of MacFoil.

Pressure resistance temperature -200 to 400 ℃
Pressure resistance 2.5 MPa
Peripheral velocity 25 m / s
PV value 19.6 MPa · m / s
pH value 0-14
Applied fluid Clear seawater, sewage, heated water, boiler feed water, thermal oil, solvent, corrosive fluid, hot air, exhaust gas etc.
Standard dimensions 3.0 mm □ ~ 25.0 mm □
Standard length 3 mL / Case
Notes It can not be used for fluids such as oxidizing acid type, oxidizing salt type, halogen compound type and combustion supporting gas.
