Parker Flare-Seal® Heavy Wall Convoluted PTFE Hoses are designed and manufactured to provide the ultimate in high purity, and corrosion/chemical resistance for sanitary applications. The unique benefit offered by a Flare-Seal hose is that the PTFE hose liner actually passes through the inside of the fitting and is then flared over the face of the fitting. This special process eliminates the problem of bacterial entrapment and adds the benefit of unrestricted flow by providing 100% PTFE coverage on all wetted surfaces. Eliminating flow restrictions, this seal is offered with braided convoluted and sanitary or flange fittings. In addition, PTFE has the lowest coefficient of friction of any tube in the market, contributing to increased media flow.

Chemically resistant and durable, Flare-Seal® PTFE Hose can be provided with a stainless steel braid, for high temperature applications, and a polypropylene braid, which features personal handling safety, and other optional braids. Platinum cured silicone and other covers are available upon request. For more information regarding available constructions and specific operating parameters for Flare-Seal® assemblies, please review the literature listed under the Product Support tab.
