KF--GJH-F Series

IECEx Explosion Proof Flexible Coupling, Flameproof Type, Two Female Fitting (2-1/2"~4")

IECEx Explosion Proof Flexible Coupling, Flameproof Type, Two Female Fitting, KF--GJH-F Series is certified with explosion proof standard, ATEX / IECEx. Whole assembly is made by stainless steel with compact and sealing structure providing strong and high-safety protection for electrical equipment used in hazardous environment or the places existing potential risk of explosion. Two end connectors can be switched between male and female thread type depending on installation requirement.

Flameproof type explosion proof flexible coupling is highly flexible to resist bending and explosion pressure meanwhile good to absorb vibration. Suitable to protect the electrical circuit in short distance or at narrow space and the location existing long term vibration. Maintaining safety of facilities in high risk environment and reduce unexpected loss.

Flameproof type explosion proof flexible coupling is especially applied for the environment containing explosive gas, dust or flyings, for example, refinery, offshore oil platform, gas plant, petrochemical plant, chemical plant, grain mill, gas station and etc.
