Frequently Asked Questions
What temperature range can these PTFE cords withstand?
PTFE packing cords operate effectively across an extremely wide temperature range from -240°C to +260°C (-400°F to +500°F), making them suitable for both cryogenic and high-heat marine applications.
Are PTFE cords compatible with shipboard chemicals and fuels?
Yes. PTFE is chemically inert and resistant to almost all industrial chemicals, acids, solvents, and fuels commonly found on vessels, ensuring reliable sealing performance without degradation.
Do I need to lubricate PTFE packing cords before installation?
No. PTFE has a naturally low coefficient of friction and is self-lubricating. Installation is straightforward without additional lubricants, though a small amount of grease may be used to ease installation if preferred.
What sizes are available for immediate ship chandler supply?
We offer PTFE cords in diameters from 3mm to 50mm, with options for cut-to-length pieces, coils, or custom spools to meet your vessel's specific requirements.
