Sealing compound for hazardous locations
This gray sealing compound is supplied in a four-ounce plastic pail and is formulated for use with intermediate metal conduit and rigid metal conduit. It prevents the spread of explosive gases through conduit systems in classified areas. The product carries CSA 22.2 No. 20 and UL 886 listings for hazardous-location installations.
Replaces field-mixed putty and unlisted mastics
Electricians can switch to this pre-measured, listed compound when a job requires a verified seal that meets the cited standards. The jump is worth it on projects where inspectors demand documented compliance and where a ready-to-use pail saves mixing time on site.
Suits contractors sealing IMC
The compound serves installers who need a listed sealing material for conduit runs exposed to explosive atmospheres. It is not intended for general-purpose plumbing, for non-hazardous electrical work, or for applications outside the stated temperature range of minus forty to sixty-five degrees Fahrenheit.

Questions about this item
Does the 4 oz pail fit standard conduit hub openings?
The 4 oz pail contains sealing compound for conduit hubs; its container size is 4 oz and the compound is applied inside the hub to seal around conductors.
What is the correct way to apply the gray sealing compound so it meets the UL 886 listing?
Pack the compound firmly around each conductor inside the conduit hub until the hub is filled, avoiding air pockets that would break the gas seal.
When should the gray sealing compound be inspected or replaced after installation?
Inspect the seal whenever the conduit system is opened or after exposure to temperatures outside the -40 to 65 °F range; replace if the compound has cracked, shrunk or lost adhesion.
