This is a broad family of products, individually developed and manufactured for unique applications. In general, these seals are static and offer low friction and good abrasion resistance characteristics. They are typically used for the aerodynamic sealing of doors, windows, ailerons, spoilers, canopies, hatches and panels. Airframe seals are typically bonded into place and can be made conductive. They can also be strategically reinforced, to offer the load and deformation properties required for variable working conditions.
Airseal is an inflatable seal, vulcanized to any customer profile. Being activated by air, water or other medium, this seal represents an economic alternative to conventional gaskets.

DD-seal Following the success of the D-seal®, TSS Skelleftea has developed a D-seal® with further improvements and with a new design. It is called double D-seal® or DD-seal, also named after the geometry of the cross-section.
All diaphragms are custom designed to suit the requirements of an application and can either be manufactured from fabric-reinforced or thin membrane rubber-only material. Higher pressures can be accommodated, by increasing the burst resistance, with synthetic fabric reinforcement. This also gives the advantages of extended product life, reduced deformation and allows the use of thinner sections to improve sensitivity of control. Diaphragms are commonly used in aircraft fuel systems, for example in control and metering valves.
