LULYLOK B-Nut Self-Locking Device

As an advanced B-nut for fittings, JPB Système’s LULYLOK solution features a unique self-locking device to ensure the sealing of pipes and tubes, thereby preventing loosening and leakage caused by severe vibration and extreme thermal conditions. 

Crucially, LULYLOK addresses safety concerns by eliminating the need for a lock-wire or safety cable, tab washers, cotter pins or any other method of fastening to secure the threaded parts within an aircraft’s engine. This eliminates foreign object damage while reducing maintenance costs and installation time.
