The VTA | Fittings | Graphite Washer is an OEM graphite sealing washer used in the rotating wiper drive assembly of VTA wiped-film distillation systems. Graphite provides self-lubricating properties and high-temperature chemical resistance, making it ideal for dynamic sealing applications in the evaporator rotation mechanism. This washer maintains a gas-tight seal at the rotating interface while minimizing friction-related wear. An essential maintenance part for VTA VKL and VKS series distillation systems.
