LOCTITE® DRI 204™ is a dry-to-the-touch, preapplied film for threaded fasteners. It remains inert on the fastener until assembly of the threads releases a quick curing resin. The resin fills all the voids in the threads and cures to securely lock and seal the assembly.
LOCTITE® DRI 204™ prevents loosening through vibration to provide locking and sealing of threaded assemblies. Typical applications include locking carburetor screws, transmission nuts, head bolts, truck axle bolts and tower bolts and also for sealing transmission bolts and pipe plugs and fittings. This product is typically used in applications with an operating range of -54 °C to +150 °C. LOCTITE® DRI 503HV™ is a high viscosity, non-toxic, thixotropic, preapplied, water-based thread sealant for automatic dispensing applications. When dried, it becomes a resilient, tight-clinging, non-curing sealant for tapered or straight threads.
LOCTITE® DRI 503HV™ provides positive sealing and resistence to vibrational loosening. The threadfilling ability and prevailing torque characteristics of this product are effective for use on sealing applications, particularly where re-adjustments are required, e.g. rear axle filler plugs, bearing adjuster nuts, pressure gauges and sensors, brake fittings, pipe fittings, and compressor pipe plugs. Other devices that this product is designed for includes; cable connectors, screws for plastic assemblies, adjustment screws, overhead fire sprinklers, shower heads, and door closure hardware. This product is typically used in applications with an operating range of -54 °C to +150 °C.
