Standard B-nuts can loosen under engine vibration and temperature cycling, leading to fuel, oil, hydraulic, and oxygen leaks. The consequences are catastrophic.
Our patented design provides a constant-friction lock, ensuring critical fittings stay secure in the most demanding conditions
Standard B-nuts are susceptible to loosening from two primary forces: harmonic vibration from engines and thermal cycling (expansion/contraction). This can lead to leaks in fuel, oil, and hydraulic lines—a leading cause of in-flight emergencies.
Vibration Loosening: Constant micro-movements can cause fittings to back off over time, often undetected during pre-flight checks.
Thermal Cycling: Extreme temperature shifts in flight cause metal to expand and contract, weakening the fitting's torque.
These failures are documented in numerous FAA & NTSB accident reports as a primary causal factor.
Bravolok is an elegant, patented solution. Its flexible band and integrated locking tooth create constant friction and a physical barrier, making it impossible for the B-nut to back off from vibration or thermal cycling.
Universal Fit: Adapts to various B-nut sizes.
Easy Installation: Slips on in seconds, no special tools required.
Lightweight & Durable: Made from aerospace-grade polymers.
Cost-Effective: A low-cost investment for invaluable safety.
