Product Description

AIGI 260L is designed to handle the unique sealing requirements of tank covers , lids and hatches. AIGI 260L starts with a rubber core overwrapped with a high quality PTFE film. This core is then overbraided with the non-absorbent, chemically resistant polypropylene yarn. The combination of the two gives this packing its excellent compressibility and elasticity. The flexible core is then wrapped with a double layer of high quality PTFE film. Finally, AIGI 260L is overbraided with a tough, pure PTFE filament jacket that protects the PTFE film barrier from damage.
