PG21 electrical cable gland designed in 28.3mm hole size of PG thread for electrical cable clamping with IP68 waterproof degree. When carrying out PG21 electrical cable glands installation, the entry cables dimension must in the clamping range of 13-18mm size.
PG21 electrical cable gland sometimes installed with PG21 conduit which is the same size in mm, it could provide ideal strain relief and keep the conduit entry into the equipment inner space the same characteristic.
PG21 electrical cable gland has the advantages as follows: Hight temperature resistance, chemical resistance, superior strain relief, high oil resistance and variable clamping ranges etc.
