SONLOK 3555 Pipe Sealant with PTFE Fabrication and Field Installation Instructions:

  • Apply 3555 onto leading 3-4 threads half way around the male pipe for sizes up to 1 ½ inches. For larger pipe sizes apply completely around the pipe.
  • Fasten fittings together. 3555 will seal even when the pipe cannot be ‘driven home’.
  • Visually inspect for a white bead of pipe sealant around the entire pipe. Repeat steps 1 and 2 as necessary.

How Anaerobic Work

Anaerobic thread sealants cure on metal surfaces when air is absent, as is the case with metal threaded connections. The adhesive fills the gaps of the threaded connection and cures quickly to form a hardened plastic seal. The sealants provide an immediate 1000 psi seal. Any excess can be wiped away.

SONLOK@ 3565 Pipe Sealant

SONLOK@ 3565 is an anaerobic pipe sealant with paste like consistency. The anaerobic sealant cures in the absence of air between close fitting metal surfaces. SONLOK@ 3565 develops controlled strength to facilitate disassembly.

  • Excellent thixotropic property prevents migration of the sealant before or during curing.
  • Ideal to seal water, gases, LPG, Hydrocarbons, Oils and other chemicals.
  • Widely used pipe sealant for variety of industrial applications such as Petroleum refining, automotive, gas compression and distribution industries, power plants, chemical processing, textile machinery, waste treatments, paper plants, etc.

SONLOK@ 3290 Weld Sealant

Sonlok 3290

SONLOK@ Weld Sealant is an anaerobic sealant which prevents porosity leaks in the welds of sprinkler system fabrication and repairs porosity leaks in the field.

  • Use in fabrication to prevent leaks in the field
  • Seals leaks in the field
  • Easy to use one component system

Sonlok 3290

SONLOK@ 3290 Weld Sealant fills all voids or imperfections and cures to form a permanent plastic seal that prevents potential leaks. Cure is initiated by the absence of air and the presence of metal, and begins to occur when the sealant wicks into the imperfections.
