PTFE Single Layer

General Rubber’s Styles 1093, 1094 and 1095 PTFE single layer flanged ducting expansion joints are designed with lower spring rates for reduced reaction forces and greater movement capabilities within a compact body. This lightweight construction is optimally designed with external or internal laminated flanges and represents the most cost-effective arrangement for low pressure flanged ducting applications. The construction includes a PTFE fluoropolymer laminated flexible element and steel retaining rings. Additionally, they are designed to absorb large all-directional movements, reduce noise and vibration, compensate for misalignments, provide access to ducting and equipment and relieve duct and anchor stresses.

General Rubber’s Style 1093 offers up to 600°F with ± 3 PSI continuous service and zero porosity in wet and dry systems. The flexible element is constructed with PTFE fluoropolymer coated high tensile fiberglass reinforcement and a 9 Mil thick laminated PTFE fluoropolymer corrosion barrier.

General Rubber’s Style 1094 offers up to 1,000°F and ± 3 PSI continuous service. The flexible element is constructed with PTFE fluoropolymer coated high tensile fiberglass reinforcement, laminated PTFE fluoropolymer corrosion barrier and a laminated woven or needle mat fiberglass insulation layer.

General Rubber’s Style 1095 offers up to 500°F with ± 3 PSI continuous service, zero porosity in wet and dry systems and a cycle life in the millions. The flexible element is constructed of a solid 30 Mil thick PTFE fluoropolymer layer and is available in thicknesses up to 60 Mil; offering the ultimate chemical resistance with no fiberglass component to fatigue.
