ForeverSeal® Pipe Thread Sealant
ForeverSeal® Pipe Thread Sealant
ForeverSeal® Pipe Thread Sealant is a high-performance anaerobic sealing compound specially formulated for metal threaded connections. It fills microscopic gaps between mating threads and cures in the absence of air to form a strong, pressure-resistant, and vibration-resistant seal.Widely used in water, gas, oil, hydraulic fluid, and industrial piping systems, it provides long-lasting and reliable leak protection under high-pressure and demanding operating conditions.
ForeverSeal® Pipe Thread Sealant Has One Clear Purpose:
Stable Sealing for High-Pressure Systems and Demanding Environments
High Pressure Resistance
Specially designed for high-pressure systems and demanding industrial operating environments.
Excellent Chemical Resistance
Resistant to water, lubricants, fuels, hydraulic fluids, refrigerants, and a wide range of industrial chemicals.
Vibration and Loosening Resistance
Locks threaded connections after curing and helps prevent loosening caused by vibration or thermal cycling.
Wide Temperature Range
Maintains stable sealing performance in both high-temperature and low-temperature environments.
Corrosion Protection
Blocks air and moisture from entering the connection, helping protect metal threads against rust and corrosion.
Easy to Apply
The single-component formula requires no mixing and can be applied directly to the threads.
Long Service Life
Suitable for permanent and semi-permanent sealing applications, providing stable long-term performance.
Application
ForeverSeal® Pipe Thread Sealant is designed specifically for metal threaded connections and high-pressure systems.
Gas Systems
Hydraulic Systems
HVAC Systems
Industrial Equipment and Piping
Oil and Petrochemical Industry
*Not recommended for use in plastic threaded connections, potable water systems, ultra-high-purity oxygen systems, or systems requiring immediate pressurization.

Working Principle
ForeverSeal® Pipe Thread Sealant fills thread gaps and cures to form a strong, pressure-resistant seal for metal threaded connections.
For best performance, apply the sealant evenly, tighten the connection to the required torque, and allow sufficient curing time before pressurizing the system.
Assembly Steps:
- 01
- Clean the male and female threads thoroughly with a wire brush and suitable cleaning solvent.
- 02
- Apply a continuous 360° bead to the leading male threads, leaving the first thread free.
- 03
- Press the sealant into the thread grooves to fill all gaps. Apply additional product to larger threads or to the female threads when required.
- 04
- Assemble the parts and tighten the connection to the required torque.
- 05
- Allow the connection to cure for 24 hours at 22–24°C to achieve full curing.
- 06
- Do not pressurize the system until the recommended curing time has been completed.
Disassembly:
Remove the connection using standard hand tools. If disassembly is difficult, apply localized heat up to 250°C and separate the parts while hot. Remove cured residue mechanically, then clean the threads with a suitable solvent such as acetone.
In high-pressure systems, a robust, pressure-resistant, and vibration-resistant seal ensures greater reliability and durability.
- The design philosophy behind Pipe Thread Sealant is:Engineered for long-term, leak-free operation in industrial environments, providing enduring and reliable leak protection under demanding conditions.
Frequently Asked Questions
- Which industries commonly use Pipe Thread Sealant?Pipe Thread Sealant is widely used in plumbing, HVAC, gas distribution, hydraulic systems, petrochemical plants, water treatment facilities, and industrial manufacturing.
- How much pressure can Pipe Thread Sealant withstand?Depending on the formulation and application, high-performance thread sealants can withstand pressures up to 69 MPa (10,000 psi).
- What materials can Pipe Thread Sealant be used on?It is suitable for most metal threaded fittings, including steel, stainless steel, brass, copper, and aluminum.
- Can Pipe Thread Sealant replace PTFE Tape?Yes. In many industrial applications, Pipe Thread Sealant can replace PTFE Tape and provide a more reliable and durable seal.
- What is the difference between Pipe Thread Sealant and PTFE Tape?PTFE Tape mainly fills thread gaps mechanically, while Pipe Thread Sealant forms a chemical seal after curing, providing higher pressure resistance, better vibration resistance, and long-term sealing performance.
