Variety of T-Tubes configurations on process lines including straights, tees and elbows


Advanced insulation designed for clean and aseptic environments


T-Tubes is an advanced insulation system specifically developed for process lines in clean and aseptic environments.


Launched in 2006 as a breakthrough in cleanroom insulation, T-Tubes have become the most trusted solution for the biotechnology, semiconductor, pharmaceutical, chemical, cosmetics and food and beverage industries.

Made from a high-performance closed cell, crosslinked PVDF foam, T-Tubes is a highly temperature and chemically tolerant, low profile insulation that allow for insulating lines in tight areas where traditional insulations (melamine and fiberglass) will not fit.


They provide critical protection for personnel working around hot processing lines. Installation is fast and easy with custom molded fittings and overlapping self-adhering tape.
