Product Description Double sphere flanged expansion bellows is composed of inner and outer rubber layers, curtain layers, and steel wire rings, which are vulcanized and then loosely combined with metal flanges or parallel joints. The double ball design improves the air tightness and waterproof performance of the product, while effectively extending its service life and reducing noise. Its unique double-layer sealing structure achieves good water tightness and air tightness, making it have excellent sealing performance.NONameMaterial1Inner/outer rubberNR,NBR,EPDM,FKM,PTEF,IIR,CR2Reinforcing cord Nylon Tire Cord3Reinforcing ringStainless Steel Strengthen Ring4FlangeQ235,SS304,SS316,PVCPerformance characteristics of rubber joints:1.
