The Knots 2U ADS-C1401 Seal Front Entry Kit is an FAA-PMA approved replacement door seal kit designed for a single front entry door on compatible Cessna aircraft. Engineered using a high-performance hybrid rubber compound, the seal forms a tight interface between the aircraft door and fuselage, helping to reduce air leakage, water intrusion, and cabin noise while improving overall cabin comfort.

The advanced sealing material is designed to conform to the mating surfaces of the airframe, compressing under door pressure and retaining the surface profile for an effective seal. This construction allows the seal to accommodate rivets, seams, and minor surface irregularities while maintaining long-lasting sealing performance throughout repeated door operation.

The kit includes the seal for one door, installation instructions, and seal lubricant to simplify installation. It is intended for maintenance and refurbishment of compatible Cessna aircraft and provides a cost-effective alternative to legacy OEM seals while maintaining approved aviation standards.
