BORESCOPE PLUGS

Self-locking solutions

INNOVATION TO CUT ASSEMBLY AND MAINTENANCE TIME DURING ENGINE INSPECTION.  

patented-technology

DESCRIPTION

A self-locking plug ensures a safe and secure seal for the various borescope inspection ports located around the engine case.

At JPB Système, we offer an innovative borescope plug mechanism that eliminates the need for lock-wire. This patented solution addresses current issues associated with borescope plugs, such as loosening due to vibrations or temperature variations, and foreign object debris (FOD) caused by lock-wire.

The JPB Système borescope plug is highly inventive and efficient. With no lock-wire involved, it significantly enhances efficiency by allowing the use of standard tools (no need for locking-wire pliers). This reduces initial installation, maintenance time, and downtime, along with minimizing human error and overall risk.

HOW IT WORKS

  
TOUCH

ASSEMBLE

ASSEMBLE

The JPB Système borescope plug features a plate that interacts with the engine interface. We design the plate with a specific shape that securely grips your interface.

TIGHTEN

TIGHTEN

The plate and body are equipped with notches that function in tandem. When you tighten our borescope plug with a standard tool, the plate and body are pressed together by a spring.

SECURE

SECURE

The pressure generated by the spring prevents any slipping between notches under vibrations or temperature variations. Consequently, there is no unexpected loosening.
