LOCTITE® SI 5926

Known as LOCTITE 5926

Features and Benefits

A 1-part, blue silicone paste for gasket replacement or gasket dressing on water pumps and thermostats.
LOCTITE® SI 5926 is a blue, acetoxy silicone paste for gasket replacement or gasket dressing, typically on applications like valve covers, timing gear covers, differential covers, oil pans, transmission pans, water pumps and thermostat housings. LOCTITE® SI 5926 cures when exposed to moisture in the air to form a rigid, flexible, silicone rubber gasket. Due to its flexible nature, it enhances the load-bearing and shock-absorbing characteristics of the bond area. It also resists aging, weathering and thermal cycling without hardening, shrinking or cracking.
