To protect the pants from extrusion and shear we to extend to inner liner to cover the worm-gear slots. These inner liners are integral extensions of the band, not separate welded or riveted extensions that will not lie true to the clamping axis.There are no bumps under the housing to jeopardize the concentricity of the seal, and no laminated coverings to disintegrate under heat ultraviolet, chemical or corrosive attacks.Additionally, Breeze liner clamps are available with extra wide bands - 1/2 ", 9/16" or 5/8 "- to spread sealing pressure over the widest possible area They are available in 100% stainless steel -. Important because silicone pants can last up to 10 years or more, and clamps that are not stainless can rust out in less than 2 years. Breeze Aero-Seal liner clamps are designed with Quadra-Lock construction Which Enables more tightening torque to be delivered to the perforations while maximizing vibration resistance.
