Rectorseal 66688 1/2"X260" TFE Tape

The Rectorseal 66688 1/2"X260" TFE Tape is a high-density PTFE thread sealant engineered for a reliable, absolute seal on all metal and plastic threaded connections. As a veteran-grade pipe thread tape, it is designed to withstand extreme environments, maintaining a functional performance range from -400°F to +500°F. This makes it an essential component for technicians working with refrigerant lines, potable water, and high-pressure gas systems where thermal stability is non-negotiable. Chemically inert and non-toxic, this industrial TFE tape provides superior lubrication during assembly, preventing galling and ensuring easy disassembly even after years of service. It meets MIL SPEC T-22730A (formerly MIL-T-27730A) standards, confirming its suitability for rigorous HVACR equipment maintenance and commercial piping applications. Whether you are sealing threaded pipe joints in cryogenic systems or high-heat boiler lines, this white PTFE tape ensures a leak-proof interface across diverse mediums including acids, solvents, and compressed air.

• Extreme Temperature Resistance: Operates efficiently between -400°F and +500°F for versatile system compatibility.
• Military Grade Specification: Formulated to meet MIL-T-22730A standards for professional-grade reliability.
• Universal Material Compatibility: Provides an airtight seal on brass, stainless steel, galvanized steel, PVC, and CPVC.
• Chemically Inert: Resistant to corrosive chemicals, fuels, and common refrigerants used in industrial cooling.
• High-Density Construction: Offers better coverage and less shredding compared to standard-grade economy tapes.

Is Rectorseal 66688 compatible with oxygen lines?
Standard PTFE tape is generally not recommended for pure oxygen service; high-pressure oxygen requires specialized green-coded oxygen tape to ensure safety.

Can I use this TFE tape on plastic PVC fittings?
Yes, this PTFE sealant is safe for both plastic and metal threads, providing the necessary lubrication to prevent over-tightening and stress cracking in PVC joints.

How many wraps are required for a standard refrigerant fitting?
For 1/2" fittings, 3 to 4 tight wraps in the direction of the threads is typically sufficient to ensure a high-pressure seal.
