PTFE Thread Seal Tape

Inert tape for threaded joints

Density-graded PTFE thread-seal tape that seals tapered pipe threads against gas, water and chemicals with a clean, inert wrap.

Seals tapered threads against gas, water and chemicals
Density grades matched to service (water / gas / chemical)
Chemically inert across the full pH range
Lubricates assembly and prevents thread galling
Wide -200°C to +260°C service range

Temperature: -200°C to +260°C
Pressure: Per threaded joint rating (medium dependent)
pH range: 0 – 14

In ServiceUSE

Where it holds the line

PTFE thread-seal tape is the simplest reliable way to seal a threaded pipe connection. Wrapped onto the male thread, it fills the helical clearance and lubricates assembly, letting the joint pull up tight without galling. SealGuard supplies it in graded densities — economical white for water, high-density grades for gas and aggressive chemicals — so the wrap matches the service. Chemically inert across the full pH range and stable from cryogenic to +260°C, it suits everything from plumbing to instrument and process lines.

Typical applications

01Threaded pipe and fitting connections
02Gas and instrument lines
03Water and plumbing systems
04Compressed-air and pneumatic threads
05Chemical and process pipework
