PTFE Tape VS Thread Sealing Cord VS Pipe Thread Sealant

Jun 14, 2025

Ptfe tape is made from 100% pure PTFE (Polytetrafluoroethylene) resins. PTFE is an master in chemistry and physics, caused PTFE to be used as a sealing material widely used in industrial applications, civil-construction, machinery, chemicals, and space navigation especially in drainage systems, and are characteristics of thread sealing, insulation, corrosion resistance anti-aging, using in oxidizing agent for a long term.

Performance Of PTFE Tape Under High Pressure

 

Thread sealing cord is a new, faster, versatile solution for sealing both metal and plastic pipe threads and fittings. It requires no curing time and delivers an instant, full-pressure seal-making it the ideal choice for quick and dependable assembly. It is dispensed directly onto threaded components from a convenient storage container, which also serves as the applicator. It's recommended for sealing tapered threads up to 4" NPT in both aqueous and non-aqueous systems. Perfect for industrial use, especially in applications requiring immediate pressure testing or minor adjustments after assembly. Suitable for temperatures up to 149 °C.

Pipe Sealing Cord 150m

 

Pipe Thread Sealant also named Liquid Teflon, is a high-quality anaerobic adhesive designed to seal and lock metal threaded connections. It cures in the absence of air and in the presence of metal, forming a durable, chemical-resistant seal that prevents leakage of gases and liquids. It is ideal for sealing against gases, water, LPG, hydrocarbons, oils, and other chemicals, and its excellent thixotropic property prevents migration of the sealant before or during curing.
