and polyproplylene fiber to create a resilient braided mechanical packing that can withstand these difficult conditions, while keeping the cargo in the tank and outside elements from getting in.
Designed Specifically for Tank Cover Applications PTFE Based Construction makes it Impervious to Almost All Chemicals Soft, Conformable yet Resilient Design Provides Excellent Sealability and Durability to withstand Repeated Tank Cover Opening and Closing Available in Bulk Lengths or as Preformed, Endless Rings Chesterton’s Lid-Lock packing is designed specifically to handle the unique sealing requirements of the tank covers, hatches and lids found on marine and rail based chemical transport equipment. In an industry where the variety of cargoes being shipped can vary on a frequent basis, it is important to have a universally compatible product sealing the tank lids, and the product must be able to withstand the repeated opening and closing that occurs during normal cargo on-loading and off-loading. Lid-Lock combines the chemical resistance of PTFE with the flexiblility of a rubber core
A.W. CHESTERTON CO.
The Lid-Lock 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.This flexible core is then wrapped with a double layer of high quality PTFE film. Essentially, this is the armor coating for the tank lid making it impervious to penetration by gas or fluids. Finally, the Lid-Lock is overbraided with a tough, pure PTFE filament jacket that protects the PTFE film barrier from damage. Lid-Lock can be supplied in bulk lengths for use as needed, or the product can be pre-formed into an endless ring custom made for each tank lid application.
