J-Flex – for custom made, precision engineered inflatable seals in premium grade elastomers.
Whatever your requirements, industrial rubber specialist J-Flex can help. J-Flex inflatable rubber seals are designed to expand when inflated to form a tight barrier against a striking surface – providing an effective seal against dust, moisture, contaminants and/or pressure differential.
Inflatable seals can be custom made using premium grade elastomers, Silicone being our speciality, though they can also be made from Fluorosilicone, EPDM, Neoprene and others. J-Flex inflatable rubber seals are produced from precision extruded profiles, thus ensuring maximum structural integrity which means better resistance to rupture and tear and superior flex life.
Valves are typically metal but are sometimes moulded depending on air pressure and application.
Whatever the length or size of the seal you require, we can help. Using our unique manufacturing technique we can provide seamless products in virtually any length or size and to your exacting specification. You can say no to vulcanised joints that offer a less effective seal.
