Hestan 14391 Pilot Lock Nut Sealed Burner Kit 3-pack

Product Description

The HESTAN 14391 is a service replacement pilot lock nut designed for sealed burner commercial cooking equipment. This three-piece kit provides the fastening hardware needed to secure pilot assemblies on sealed burner units, ensuring consistent flame positioning and a stable, gas-tight connection at the pilot fitting. Licensed commercial kitchen technicians and qualified gas appliance service professionals install this part during routine maintenance or burner assembly replacement. The lock nut design resists loosening from vibration and thermal cycling common in high-use commercial range environments.

This kit is used in commercial foodservice applications where sealed burner ranges and cooking suites require pilot assembly service. The package of three nuts allows a technician to address multiple burners in a single service call or maintain a stock of critical fasteners on the service vehicle. It is suited for professional kitchen environments running continuous cooking cycles where pilot reliability is essential.
