Description
Permabond® HH190 300 mL Caulk Tube is an anaerobic curing flange sealant used to replace pre-cut gaskets in rigid metal assemblies.
The 300 mL cartridge format is suited for higher volume production and larger flange assemblies requiring consistent bead application. HH190 forms an instant pressure seal and ultimately seals up to 5000 psi.
