DESCRIPTION
LULYLOK™ is a technology ingeniously designed and patented by JPB Système as part of our mission to deliver innovative solutions for securing fluid and gas connections in the industry.
LULYLOK™ is a B-nut for fittings equipped with a self-locking mechanism. This patented feature prevents tension loosening under harsh conditions such as vibrations, temperature variations and exposure to corrosive agents.
LULYLOK™ can be easily assembled on various types of fittings and operates without the need for a lock-wire or complex positive locking mechanisms. As a result, LULYLOK™ reduces both initial installation and maintenance times while eliminating the risk for Foreign Object Debris (FOD).
