MK type ULTRATHAN pneumatic piston seal with integrated guiding and cushioning function, can be used with or without cylinder piston ring seal permanent. When used in the piston with a permanent magnet, the magnetic ring is wrapped in the MK-type guide seals. MK piston seal has the following advantages when used in the cylinder:

• specially designed sealing lip structure improves sealing reliability, while reducing friction.
• As the piston seals, MK while providing direct function. Because of its structure and shape, MK can not bear the main radial force used or for long stroke piston.
• decompression starting from 32mm bore groove design to achieve the best functional results.
• With duct-one buffer designed to provide mechanical cushioning for the cylinder.
• Special structure design by the end of the bit buffer, to achieve optimal piston seal.
• The large number of proven polyurethane applications, bringing longer working life.
• suitable for both dry air or air containing lubricating oil.
• asymmetric groove structure to ensure that seals tightly fitting retention force on the piston.
• recessed retaining groove, making installation easier.
• integrated design, integrated in a sealing element, a guide, a buffer three functions, reducing the number of parts.
• maximize the reduced installation space.
