Loctite Sealant PasTE For Thread Sealing
The Loctite yellow 250ml gasket sealant paste is a general-purpose thread sealant for straight/straight and straight/taper threads and fittings. It fills the space between threaded parts and seals and locks at the same time. This paste is composed of methacrylate and has an excellent chemical and thermal resistance. It is designed for the locking and sealing of metal pipes and fittings as well as other threaded assemblies. This product provides an instant, low-pressure seal for metal pipes and fittings. It will not creep, shrink or shred. The product offers less migration of liquid product after application.
