Chico A and Chico X Sealing Compounds and Fiber

Crouse-Hinds series Chico sealing compounds and fiber are used to form a seal around each electrical conductor and between them, and inside of the sealing fitting to restrict the passage of gases, vapors or flames through the sealing fitting.   

Chico A sealing compound is a water soluble powder that can be easily mixed and poured.  The dense compound expands slightly when hardening and bonds to inner walls of sealing fittings.  Chico A-P Intrapak is packaged in a two compartment plastic pouch with precise amount of water for mixing.  No measuring is required, speeding up the installation process.  Chico X fiber forms a dam between the integral bushing of the sealing fitting and the end of the conduit and around the electrical conductors entering the hub.  It is a mineral wool that packs easily, forming around each conductor. 

Chico A, Chico A-P and Chico X are approved for use in Class I, Division 1, Groups A, B, C, D and Class II, Division 1, Groups E, F, G hazardous areas.
