FORMULA‐8 uses PTFE in a shear-sensitive white thixotropic paste to seal threaded joints with PTFE strings when torqued. The seals are formed over the entire thread length. Even fine threads in instrumentation systems are sealed effectively over the entire thread length. It won’t deteriorate from ‐400°F to +500°F. It is stable in pressures up to 10,000 psi and in vacuums 10‐3 torr. FORMULA-8 has been tested and certified for use in gaseous and liquid oxygen by NASA (ASTM G72) and also by BAM (German Federal Institute for Materials Testing).

Do not allow Formula-8 to freeze.
