Loctite 3135775 Thread Sealant, PTFE, Non-Curing, 1 Pint, 16 fl. oz., Bottle, 5113 Series

LOCTITE 5113 Thread Sealant with PTFE

General-Purpose, Non-Curing Paste for Reliable Metal Pipe Sealing

The LOCTITE 5113 is a high-performance, solvent-based thread sealant formulated for dependable sealing and lubrication in metal piping systems. Designed for engineering and maintenance professionals, this one-part, non-curing paste delivers consistent coverage and controlled flow—similar to SAE 40 motor oil—for efficient application and long-term serviceability. Its PTFE-enhanced formulation ensures leak prevention across threaded pipes, fittings, and flanges, even under high pressure and variable temperatures.

With excellent chemical resistance and compatibility with both metal and select plastic components, LOCTITE 5113 is ideal for water systems and lines carrying alkalis, ethylene glycol, petroleum products, and lubricating oils. The white, brushable paste applies easily and enables straightforward disassembly when required for maintenance.

Features & Benefits:

• Non-Curing Formulation
