3M 5490 Brown PTFE Tape, 33 m x 25mm x 0.09 mm

This PTFE tape provides a low-friction sealing layer for threaded pipe joints and general industrial sealing tasks. It is intended for use where a heat-tolerant, chemically resistant film is required to aid assembly and reduce leak paths in fluid and gas systems within automation, electronics, electrical and mechanical environments.

• Silicone-based adhesive maintains bond across wide temperature range
• Withstands temperatures from -54°C to 260°C for high-temperature applications
• Tensile strength of 304N/100mm resists tearing during installation
• Thin 0.09mm film conforms easily to threads for improved sealing
• 25mm width allows Rapid coverage of standard pipe threads

• Suitable for sealing threaded fittings in pneumatic systems
• Ideal for use on HVAC and process-plant piping joints
• Used with instrumentation tubing requiring thin sealing film
• Can be used for maintenance of electrical conduit couplings
• Suitable for mechanical assembly where heat-resistant sealant is needed

Each roll yields 32.9m of sealing film, allowing multiple service visits from a single unit and reducing replenishment frequency.

The tape is brown, which helps distinguish it from other common thread tapes during assembly and stock checks.

The silicone adhesive offers good adherence to a range of metallic and polymeric substrates while retaining performance at elevated temperatures.

The product is supplied as a narrow roll 25mm across to match common plumbing and instrumentation thread sizes.
