Thomas & Betts DX-1 – Frequently Asked Questions
1) Can Thomas & Betts DX-1 duct seal be used as a firestop?
No. DX-1 is for moisture and air sealing only and is not classified as a fire stop. If the penetration is through a rated assembly, you need a listed firestop sealant or putty instead, not DX-1.
2) What temperature range can DX-1 sealing compound handle once installed?
In service, DX-1 holds from -40 F up to 250 F, so it covers outdoor meter bases and unconditioned attics and crawl spaces. Applying it is a narrower window: work it between +20 F and 212 F. In a cold shop or truck below 20 F it will not knead or tool properly, so warm it before use.
3) Is DX-1 sold individually or do I have to buy a case?
The unit of measure is Each, but orders go in multiples of 50 and the outer package holds 50. So the practical buy is a 50 unit carton, which suits stocking a truck or an MRO crib rather than picking up one piece.
4) Do I have to wait before painting over DX-1?
No waiting. DX-1 can be painted immediately after application, so a crew can seal a conduit entry and finish the wall in the same visit. It also contains no asbestos and has no unpleasant odor, which matters for occupied units and healthcare or school work.
5) Is DX-1 RoHS compliant for institutional and government purchasing?
Yes, DX-1 is listed RoHS compliant, which is the box most public agency, healthcare and education procurement specs want ticked on an electrical consumable.
6) What is the correct Thomas & Betts part number to order this duct seal under?
Order it as Thomas & Betts DX-1. That is the manufacturer part number and the only model in the family, so there is no size or variant choice to make on the order form.
7) What color is Thomas & Betts DX-1 and will it show on a finished wall?
DX-1 is grey. On exposed masonry or a panel interior it blends in reasonably; where appearance matters, paint over it right after application, which the compound allows.
8) How much does a unit of DX-1 weigh and how big is the carton?
Each piece runs 1.05 lbs. The 50 unit shipping carton measures 12.6 by 12.5 by 9.2 inches, which is useful if you are planning shelf space in a supply room or stock room.
