Bridgeport Fittings DS-100 – Frequently Asked Questions

1) What is duct seal compound used for on an electrical job?
Bridgeport duct sealing compound is a hand-moldable putty used to seal around boxes, flashings and service entries. It stays pliable so you can press it into an opening and rework it later, but it holds a tight seal once packed. Common uses are weatherheads and service entrance penetrations, meter socket knockouts, and flashing penetrations on commercial, residential and industrial work.
2) Will duct seal corrode the metal enclosure or conduit it's packed against?
No. The Bridgeport #1003 compound is formulated non-corrosive to metal, so you can pack it against steel boxes, meter cans and raceway without worrying about it attacking the enclosure or the fittings over time.
3) Does Bridgeport duct seal contain asbestos?
No asbestos. Older duct seal putties were asbestos-bearing, which is why crews doing renovation work ask. The Bridgeport #1003 compound is an asbestos-free formula, so there's no abatement concern when handling or removing fresh material.
4) Is Bridgeport duct sealing compound UL Listed?
Yes, it carries UL file R14730. If your inspector or spec requires a listed sealing compound for the electrical penetration, that file number is the reference to put on the submittal.
5) Is duct seal a fire stop product?
No. This is an electrical sealing compound for boxes, flashings and service entries, not a firestop. Bridgeport's #1003 compound carries UL file R14730 as a duct sealing compound; it is not offered here as a rated through-penetration firestop. For a rated wall or floor assembly you need a product listed for that specific assembly.
6) Can you paint over duct seal to match the wall?
Yes. The compound is paintable, so on a visible service entry or an exposed box penetration you can finish over it to match the surrounding surface instead of leaving a gray blob on the wall. That matters on storefronts and occupied units where the seal lands somewhere a tenant can see it.
7) What size and pack should I order, the 1 lb or the 5 lb?
Duct seal comes in 1 lb. and 5 lb. sizes, each offered in a 10 slug or 50 slug package option. The slug count is how many individual bars are in the carton, so a 50 slug box is the one to buy if you're stocking a van or a facility MRO crib and pulling one bar per opening; 10 slugs suits a single job. Ordering references include DS-100 and DS-500.
