Product Description

PTFE Tank Lid Seal Packing - Style 1005

Our PTFE tank lid seal packing is made by spiral wrapping of PTFE tape over a core of elastomer, jacketed with inert polypropylene yarn braided structure is spirally wrapped to provide an impermeable barrier to liquids. Final jacketing of polypropylene yarn gives complete protection to the packing and makes it abrasion resistant. The unique core construction of PTFE tank lid seal packing enables the packing to be stitched together to form an endless seal, thus preventing the chance of any leakage at the joint

PTFE tank lid seal packing has a multi-layer construction, which assures excellent conformability to the packing recess, compression and resilience properties, ensuring reliable, gas tight sealing performance every time the tank hatch or lid is closed and tightened. The Lid-Lock of PTFE tank lid seal packing 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. Finally, the Lid-Lock is overbraided with a tough, pure PTFE filament jacket that protects the PTFE film barrier from damage.

Applications and Advantages of PTFE Tank Lid Seal Packing

PTFE tank lid seal packing is designed for sealing tank lids, main hatches, Butterworth hatches, inspection hatches on board chemical and product tankers and tank lids on tank containers, road tankers and rail tank cars carrying all known bulk liquids in all IMO classes

The PTFE tank lid seal packing is really a gas-tight environmental seal, it can protect cargo from sea water ingress and it can withstand repeated opening and closing cycles. PTFE tank lid seal packing is unaffected by steam and other tank cleaning systems and is suitable for smooth recesses in stainless steel lips as well as those with rougher surface finishes.
