How to select an Elaflex rubber bellows


1 Temperature & Pressure2 Rubber Compatibility3 Diameter and Length4 Flange Drilling & Restraints5 Movements6 Let us help
Elaflex bellows Temperature & Pressure Temperature is the most critical as it directly influences the choice of rubber - but also the actual pressure capability of the bellows. The stated maximum rated pressure is maintained up to around 50ºC for most rubber bellows, for higher temperatures check the data in the Range tab.
Elaflex bellows Rubber CompatibilityThe rubber compound used for the inner layer of the bellows must be compatible with the working fluid. Drinking water requires a WRAS approved EPDM, oils require Nitrile and so on - our Bellows Finder can help you with finding the right rubber.
Elaflex bellows Diameter and LengthMoulded bellows are manufactured in set combinations of diameters and lengths. However, our handmade Safetech range can be manufactured in any diameter and length to suit your application, only the more standard sizes are shown on the Safetech range tab.
Elaflex bellows Flange Drilling & Restraints Any flange drilling can be supplied; if you are uncertain about what you already have installed our Flange Finder will help you identify it. The HVAC and Elaflex ranges have swivel flanges; the Safetech range has full face rubber flanges. Our web shop stock is PN10/16. Bellows will exert a pressure force on the pipe (see FAQ) which must be restrained or absorbed at the piping anchors. All our flanged rubber expansion joints are available with tie rods and we can offer hinges or gimbals on the Elaflex and Safetech products.
Elaflex bellows MovementsMoulded rubber bellows have a defined movement range, which is shown for each type in the Range tab, movements listed are non-concurrent (see FAQ). A Safetech bellows will be designed to meet your required movements.
