LOCTITE 503 DRI Pre-applied Sealant
(Known as Loctite 503 Vibra-Seal )
LOCTITE® 503™ DRI Pre-applied Sealant is a low viscosity, non-toxic, thixotropic, preapplied, water-based thread sealant for bulk processing applications (tumble or flow coat). It provides "constant on" torque. When dried, it becomes a resilient, tight clinging, non-curing sealant for tapered or straight threads. The product provides excellent solvent resistance and an operating temperature range from -54°C to 150°C (-65°F to 300°F).
