Our Thread Sealing Products
LOCTITE thread sealants, available in liquid or stick form, prevent leakage of gases and liquids on metal pipes and connections. Designed for low and high pressure applications, they fill the space between threaded parts and provide an instant, low pressure seal when used on taper/ parellel joint combination. When fully cured, they seal to the burst strength of most pipe systems.

Advantages of LOCTITE Thread Sealants as Compared to Traditional Sealant Types
- Single-component – clean and easy to apply
- Do not creep, shrink or contaminate systems
- Can be used on any size of pipe fitting
- Replace all types of tape and hemp/paste sealants
- The seal resists vibration and shock loads
- Available with major agency approvals
- Protect mated threaded areas against corrosion
Why LOCTITE Thread Sealants Are Superior to Traditional Sealant Types
Solvent-based sealing compounds can shrink during cure as solvents evaporate. Fittings must be re-torqued to minimise voids. They lock the assembly by a combination of friction and deformation.
PTFE tape lubricates in off direction, allowing fittings to loosen under dynamic loads and resulting in loss of clamping force and leakage. Dynamic loads may accelerate creep, causing leakage over time. The lubricating effect of PTFE frequently results in over-tightening of fasteners, adding stress or causing breakage of parts. Application requires good professional skills to avoid stressing fittings or castings.
Hemp & Paste are slow to apply, are messy to assemble, and interfere with the torque needed to obtain the correct pre-stress. These can require re-work to achieve a 100% seal of the assembly.
