P8400 Series Vinyl Neoprene Foam Tapes
Pres-On P8400 Series Vinyl Neoprene Foam Tapes offer a uniform, closed cell structure that resist the absorption of water, chemicals and other fluids. These tapes also provide good load bearing qualities, and help maintain a permanent, positive seal with the ability to fill larger gaps to seal out water and air. Fire-rated (UL, FM).
