Product List for Bearings, Seals & Crossflon PTFE Sliding Systems
PTFE THREAD SEAL TAPE
Polytetrafluoroethylene (PTFE) is an almost chemically inert thermoplastic material, which retains useful mechanical properties over a wide range of temperatures. These characteristics have caused PTFE to be used as a sealing material in a wide range of applications.
Threaded components with leak-proof specifications are notoriously difficult to seal, and the properties of a thin PTFE tape make this the ideal sealing solution. It is clean, easy to handle, and is easily applied by simply wrapping round the threads and connecting the mating parts. Its non-stick properties also make it easy to remove whenever the thread is undone. For example, when maintenance is required.
Beldam Crossley manufactures Threadseal tape 3313. Unsintered threadseal tape 3313 contains no materials that are combustible in the presence of oxygen, and conforms to BS 7786. This tape is suitable for use with liquid oxygen systems and has BOC testing approval.
