PILOT LIDPACK® 3800 is identical in construction as 3500 but with a core of EPDM rubber. Carries acceptance by the United States Coastguards for use with Propylene Oxide and α-Butylene Oxide (1,2 -Epoxybutane).
PILOT LIDPACK 3800 is a major development in tank lid sealing and has now been proven after many years of service. A hollow core, spirally wrapped with layers of PTFE tape, provides resilience, and ensures excellent recovery after compression when the tank lid is being continually opened and closed.
On the outside of the polypropylene layer, a double wrapping of unsintered PTFE tape gives complete impermeability to liquids and chemicals. The final outer braid of PTFE yarn gives the finished packing strength and resists abrasion.
