Lid-Lock Packing 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 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. 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.

Lid-Lock Packing

Chesterton’s Lid-Lock packing is designed specificallyto handle the unique sealing requirements of thetank covers, hatches and lids found on marine and rail based chemical transport equipment.In an industry where the variety of cargoes beingshipped can vary on a frequent basis, it is importantto 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

and polyproplylene fiber to create a resilient braidedmechanical packing that can withstand these difficult conditions, while keeping the cargo in thetank and outside elements from getting in.

The Lid-Lock starts with a rubber core overwrappedwith a high quality PTFE film.This core is then overbraided with the non-absorbent, chemically resistant polypropylene yarn.The combination of thetwo gives this packing its excellent compressibilityand 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 lidmaking 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. Contact your local Chestertonrepresentative for more information.
