Product Description

Loctite 561 Thread Sealant, Semi-Solid 19g is a rapid curing thread sealant designed to provide immediate low pressure sealing for threaded pipe and fitting connections. Its creamy semi-solid consistency allows for precise application to threaded areas without dripping or running. Once applied, it cures to form a durable, flexible seal that protects against leakage, shock, vibration and prevents threaded connections from loosening.

Key features and benefits include:

  • Cures quickly to form an instant seal, even under low pressure conditions
  • Controlled lubricity prevents thread galling during assembly and disassembly
  • Protects threaded connections from corrosion and rust
  • Remains flexible to accommodate vibration and thermal expansion/contraction
  • Ideal for low pressure applications including water, air, gas and refrigeration lines

Suitable for sealing threaded connections on pipes and fittings up to 1" in diameter. Conforms to NSF Standard 51 for use in commercial and residential potable (drinking) water systems. Available in a convenient 19g tube for precision application of just the right amount of sealant.
