121 Tech Drive Sanford, FL 32771 (407) 322-4000 Fax: (407) 321-9700 www.hernon.com ISO 9001:2008 Registered High Performance Adhesives and Sealants Technical Data Sheet Self Seeler 604 Product Description Product Benefits Hernon Self Seeler 604 is a low viscosity, tough, preapplied, non-hardening threaded sealant. When dried, it becomes a resilient, tight clinging, non-curing sealant for tapered or straight threads. It provides an instant seal on different pipe threads and can be used up to eight (8) times without recoating. • The preapplied coating eliminates liquid and paste migration problems and concerns during installation. Self Seeler 604 is water based, non-toxic, safe and can be applied easily without special handling precautions. It contains a bacteria and fungus preservative to inhibit growth of microorganisms. It also provides resistance to vibrational loosening because of its prevailing torque characteristics. It is very effective on non-locking applications. • Ideal for field assembly – precoated parts are always there and ready for the task. • Precoated fittings can be stored for immediate delivery and assembly. • The preapplied coating is tough, resilient and resists shredding and peeling during assembly. • Precoated parts have a shelf life of several years. Typical Applications UL Classification Classified by Underwriters Laboratories Inc. MH14222 as to fire hazard only. Self Seeler 604 is Classified 0 to 10 less hazardous than paraffin oil in respect to fire hazard. For use in devices handling gasoline, petroleum oils, natural gas (pressure not over 100 psig), butane and propane, not exceeding 2 in. pipe size. Suitable for single assembly ("insertion") use when applied and dried prior to assembly in accordance with the manufacturer’s instructions. • Door Closure Hardware • Pipe Fittings • Compressor Pipe Plugs • Shower Heads Product Certification • Plumbing Parts • Bearing Adjuster Nuts • Broken Fittings • Overhead Fire Sprinklers • Brake Fittings Pressure Gauges Typical Properties Property Chemical Type NSF International Certified to ANSI/NSF Standard 61 for use in commercial and residential potable water systems not exceeding 82ºC (180ºF). Product Features Specific gravity Instant Seal ½ inch NPT fittings Operating Temperature On Part Life Flash point • No cure time is required. The preapplied film provides instant sealing for NPT threads up to 4 inches in diameter immediately upon installation Typical Performance • Mechanically, the dry film generates prevailing torque characteristics making threaded parts resistant to vibrational loosening after installation. Torque Strength 3/8” -16 nuts and bolts Property • Corrosion is inhibited between mating threads. The threads are safely sealed from contact with the atmosphere by the coating. Seating Torque Breakloose Torque • Safe to use with plastics. It will not craze or attack plastic components. Prevailing Torque
