Stenflex rubber expansion joint type AR-2 or type AR-4
Product information
Stenflex rubber expansion joint type AR-2 and type AR-4 are A expansion joints reinforced with high-quality aramid layers. Various flange drillings are possible in this set-up. Thanks to the aramid inlays, the AR expansion joints are PN 25 expansion joints suitable for applications up to 130°C. These expansion joints are designed to handle higher pressure loads.
Type AR-2 and type AR-4:
- With type AR-2, the tension rods are only limited on the outside, so that the expansion joint cannot extend.
- With type AR-4, the tension rods are limited on the outside as well as on the inside, so that the expansion joint cannot extend and cannot be pressed in. As in the case of a vacuum.
