B8X-272 is engineered for permanent retention of large-diameter threaded assemblies exposed to extreme heat and mechanical stress. Its medium viscosity ensures controlled application while providing deep thread engagement. Ideal for critical joints in power generation, oil & gas, and heavy machinery where long-term reliability at elevated temperatures is essential.

Performance Highlights
- Extreme Temperature Resistance: Continuous service up to 232°C (450°F)—among the highest in anaerobic threadlockers.
- Optimized for Large Fasteners: Formulated for M25+ bolts, studs, and flange connections.
- Permanent Locking & Sealing: Prevents loosening and leakage in high-vibration, high-pressure systems.
- All-Metal Compatibility: Bonds reliably to carbon steel, stainless steel, and plated surfaces.
Typical Applications
- Turbine and compressor casings
- Engine block and manifold studs
- Flanged pipe connections in refineries
- Mining and drilling equipment
- Large electric motor housings
Application Notes
- Apply to clean, dry threads; assemble immediately.
- Full cure in 24–72 hours depending on temperature and gap.
- Disassembly requires localized heating to >250°C.
- Store sealed at room temperature (<25°C).
Available in 20 ml and 250 ml bottles.
