SONLOK® Thread Sealants

SONLOK® Thread Sealants are high-performance anaerobic sealing compounds engineered to replace traditional PTFE thread tape for reliable, long-term leak prevention. Designed for fast assembly and dependable sealing, these sealants cure quickly in the absence of air when confined between metal threads, forming a secure, pressure-resistant bond that seals and locks threaded joints.

Once fully cured, SONLOK® thread sealants withstand pipe pressures of up to 1,000 PSI and provide excellent resistance to industrial oils, hydraulic fluids, and a wide range of gaseous media. Commonly used on metal pipe joints in oil and gas, LPG, water, and sewerage systems, these sealants help prevent leaks, reduce maintenance, and improve overall system reliability. Manufactured by Parson Adhesives Inc, SONLOK® thread sealants deliver professional-grade performance for critical piping and fluid-handling applications.
