Thomas & Betts CTB – Frequently Asked Questions

1) How much Thomas & Betts CTB sealing compound do I actually get, and how is it packaged?
Each Thomas & Betts CTB bottle holds 118.29 ml of compound, and the order unit is a 100-bottle pack. Inside that, bottles come boxed 12 to an inner carton, with 72 to an outer. Figure roughly 32 lbs per 100 bottles for freight and shelf planning.
2) Is the CTB compound a petroleum grease that will attack wire insulation?
No. CTB is a silicone-based, non-petroleum polymer grease, so it won't break down insulation or electrical components the way a petroleum grease can. That is the main reason it gets specified over generic greases for sealing conductors and connectors.
3) Will the Thomas & Betts CTB compound hold up in a wet outdoor enclosure?
It is formulated non-water soluble, so the seal stays put in wet or high-humidity conditions. It blocks oxygen and moisture at the connection, which is what stops corrosion in outdoor enclosures and below-grade boxes.
4) What is the CTB sealing compound used for on an electrical job?
It's a jointing compound for sealing electrical connections, conductors and connector barrels against moisture and oxygen. Typical uses are outdoor enclosures, industrial and commercial installs, service work, and MRO repairs where a joint has to stay corrosion free.
5) Is there one part number for the CTB compound, or multiple versions to pick from?
One configuration: Thomas & Betts part number CTB, the black silicone-based compound in a 118.29 ml bottle. There is no alternate size or color to specify when you order.
6) Is CTB compound safe to handle bare-handed in the field?
The formulation is non-toxic and skin-safe for professional handling, so crews can apply it without irritation concerns. That matters when you are buttering connections by hand in a panel rather than using an applicator.
7) What carton dimensions should I plan for if I'm stocking CTB compound on a parts shelf?
The 12-bottle inner carton measures 7.188 x 5.875 x 6.875 inches, and the 72-bottle outer measures 17 x 15.1 x 7.5 inches. Inners break out nicely into a van bin or a shop shelf without rehandling the whole master pack.
8) What color is the Thomas & Betts CTB compound, and will it show on finished work?
It's black, so it blends into conduit, connector bodies and enclosure interiors rather than standing out on a finished install. If you need to visually confirm coverage on a dark connector, bear that in mind during application.
