Thread Sealants for Fire Suppression Systems

How to Use Thread Sealants for Fire Suppression Systems

Hernon Manufacturing’s thread sealants for fire suppression systems offer reliable fast sealing for pressurized water and chemical process piping. Hernon’s Dripstop® family of products can help to seal pressurized systems ensuring the fire retardant goes only where it is needed. This leads to improved dispersion patterns and lower corrosion risk across the system. Simply apply Hernon’s thread sealant paste directly onto the front threads of a fitting and fasten the fitting together. The paste fills gaps between threads with a non-reactive sealant to keep systems leak-free and secure from contamination. Hernon’s Teflon enhanced thread paste will not shred and break like tapes that can clog filters. These thread sealants maintain a flexible barrier that can be reused multiple times and offers the added benefit of resisting rust and galvanic corrosion. This helps threaded assemblies to be easy to unscrew when maintenance is required while keeping the system leak-free.

Some thread sealants can be pre-applied during manufacturing stages and shipped to job sites for assembly reducing the amount of on-site labor required. Be sure to ask about Hernon’s pre-applied sealants as well as the Autosealer® 2600. The Autosealer® 2600 is a pneumatic applicator for dispensing high-viscosity Hernon® products onto threaded pipe fittings and nipples.

Hernon® offers an entire family with dozens of thread-lockers and thread-sealants designed to bond or seal specific materials and ensure the perfect solution for your fire suppression system.
