Permatex High-Temperature Thread Sealant

Permatex High-Temperature Thread Sealant

Permatex High Temperature Thread Sealant is a medium
strength anaerobic sealant with PTFE for tapered pipe threads.
This sealing compound is of a white, creamy paste
consistency. The high lubricating properties of this compound
prevents galling on pipe threads and fittings. It will provide
immediate low pressure sealing and allow for the readjustment
of fittings shortly after assembly. After 72 hours the joint is
sealed to pipe burst pressure. This product has a medium
solvent resistance and will withstand temperatures to 400F
(204C). This product is not recommended for use on
plastic piping.

PRODUCT BENEFITS

• Resists leakage, vibration loosening, moisture, hydraulic
  fluids, diesel fuels.
• Lubricates threads for easy assembly and disassembly.
• Will not shred or wear like tapes.
• Parts may be repositioned for up to 24 hours after
  application.

TYPICAL APPLICATIONS

• Head bolts into through holes
• Oil PSI sending units/sensors
• Oil and coolant lines
• Fuel fittings
• Rear axle fill plug
• Brake and power steering fittings

DIRECTIONS FOR USE

1. For best performance, surfaces should be clean and free
   of grease.
2. Product should be applied to the thread engagement
   area in sufficient quantity to fill all engaged threads.
3. Use accepted trade practices to assemble and wrenchtighten fittings until proper alignment is obtained.
4. Very large thread sizes may create large gaps, which will
   affect cure speed and strength.
5. For maximum pressure and solvent resistance, allow at
   least 24 hours for the product to fully cure before filling
   and pressurizing system.
6. Fittings assembled with Permatex High Temperature
   Thread Sealant may be disassembled with normal hand
   tools.
7. For large pipe diameters (over 1"), heat may be required
   to disassemble fittings.
8. Fittings may be reused by removing loose sealant
   residue with a wire brush and reapplying sealant.

FOR CLEANUP

1. Wipe off any material outside the joint with a dry cloth.
2. Clean hands with Permatex Fast Orange® hand cleaner
   or soap and water.
3. Cured material must be removed with Permatex Gasket
   Remover.

TYPICAL CURING PERFORMANCE

Cure speed vs. temperature

The rate of cure will depend on the ambient temperature. Full
cure is attainable in 24 hours at room temperature, 72F
(22C), or 1 hour at 200F (93C).

Cure speed vs. substrate

The rate of cure will depend on the material used. Permatex
High Temperature Thread Sealant will react faster and
stronger with Active Metals. However, Inactive Metals will
require the use of an activator (Surface Prep) to obtain
maximum strength and cure speed at room temperature.

Cure speed vs. activator

Where cure speed is unacceptably long, or large gaps are
present, applying an activator (Surface Prep) to the surface
will improve cure speed. Assemblies will fully cure in 24 hours
with activator.

GENERAL INFORMATION

This product is not recommended for use in pure oxygen
and/or oxygen rich systems and should not be selected as
a sealant for chlorine or other strong oxidizing materials.
For safe handling information on this product, consult the
Material Safety Data Sheet, (MSDS).

STORAGE

Products shall be ideally stored in a cool, dry location in
unopened containers at a temperature between 46F and 82F
(8C and 28C) unless otherwise labeled. Optimal storage is
at the lower half of this temperature range. To prevent
contamination of unused product, do not return any material to
its original container.
