Crouse-Hinds CHICO A3 – Frequently Asked Questions

1) How much conduit seal does one pound of Chico A3 sealing compound fill?
A 1 lb container of Crouse-Hinds CHICO A3 yields 23 cubic inches of sealing compound. That figure is what you estimate your job from: total the packed volume of each seal fitting you have to fill, then divide into 23 cu in to work out how many pounds to bring to site. Mixed compound has a working life once wetted, so most electricians size the pour to the fittings they can dam and fill in one go rather than mixing the whole pound at once.
2) Is Chico A3 approved for Class I Division 1 hazardous locations?
Yes. The CHICO A3 compound carries a Class I, Division 1 NEC hazardous rating and is intended for hazardous/classified locations, meeting NEC/CEC requirements for conduit sealing. Class I Division 1 is the classification where ignitable vapor concentrations can be present in normal operation, which is why the seal is required in the first place.
3) Does the Chico A3 sealing compound include the fiber dam, or do I order that separately?
CHICO A3 is the sealing compound alone, supplied in a 1 lb container. The packing fiber that dams the fitting below the pour is a separate item, as is the seal fitting itself. Plan on three pieces for a complete seal: the conduit seal fitting, the damming fiber, and the compound.
4) What kind of facilities actually require a compound like this in the conduit runs?
Refineries and petrochemical plants, chemical processing, paint manufacturing, solvent storage areas, gasoline dispensing stations, and aircraft hangars are the typical settings for CHICO A3. All of them are classified environments where flammable vapors can be present, so the conduit seals that isolate those areas have to be poured with a compound rated for Class I, Division 1 service.
5) Is the Chico A3 compound the same thing as Chico X fiber?
No, and they are not interchangeable. CHICO A3 is the pourable sealing compound that hardens into the vapor barrier inside the seal fitting. The fiber is the packing material you tamp in first to dam the fitting so the compound does not run down the conduit. A Division 1 seal needs both, and pouring compound without a dam wastes the pound.
6) Will Chico A3 satisfy a Canadian inspector, or is it US code only?
Both. The CHICO A3 compound is built to NEC/CEC standards, so it covers National Electrical Code work in the US and Canadian Electrical Code work north of the border. For MRO buyers standardizing a compound across plants in both countries, one part number does it.
7) How much shelf space does a container of Chico A3 take in the truck or the stockroom?
Each 1 lb unit measures 3.97 inches in height, 3.97 inches in length/depth, and 4.13 inches in width, so it is roughly a cube a little over four inches on a side. Small enough to carry several on a service truck when you are pouring multiple seals on one shutdown.
8) What is the exact part number to order this Crouse-Hinds sealing compound?
Order it as Crouse-Hinds CHICO A3. The A3 designation is the 1 lb size in the Chico compound line, and it is the number to quote on a requisition or hand to a distributor.
