Style 112A 2-Convolute Flexible Coupling

PTFE expansion joint

Style 112A Convoluted PTFE Bellows Flexible Couplings offer the best combination of low spring-rate flexibility, temperature resistance, and the chemical inert properties of PTFE material. The Style 112A 2-Convolute Flexible Coupling were designed to meet the needs of the HVAC, high-technology, and chemical/petrochemical industries. The “Tef-Flex” bellows connectors are versatile and will 1) absorb pipe movements and stress; 2) isolate mechanical vibration; 3) reduce system noise; 4) protect against surge forces. “Tef-Flex” connectors are suitable for connection to metallic piping or plastic lined metallic piping.

The construction of the connector utilizes 2, 3, or even 5 molded convolutions of white PTFE. These convolutions are reinforced with metallic rings between the bellows for pressure rating and stability. Standard galvanized ductile iron backing flanges are protected by the lip of the PTFE bellows, so that all wetted surfaces are PTFE. Steel limit rods are factory installed. Additional convolutions provide greater movement capability. Style 112(316)A include Type 316 stainless steel backing flanges and hardware. Options include high purity cleaning and packaging.
