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 Anaerobics 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.
