Rubber Expansion Joints
Moulded elastomeric flexible connectors that absorb vibration, noise, thermal movement and misalignment on pumps, HVAC, water and process lines — five builds covering DN15 to DN1400, flanged, threaded and flangeless.
The Range
T270Single SphereSingle arch — absorbs axial, lateral and angular movement while damping vibration and noise.DN 32 – 120040 barView product 
T282Double SphereTwin arch — roughly double the movement take-up in the same face-to-face length.DN 32 – 60025 barView product 
T280Full Face SpoolIntegral full-face rubber flanges — gasket-free sealing for high pressure and vacuum.DN 32 – 100040 barView product 
T281Threaded UnionUnion ends for small-bore threaded pipework — fitted without flanges or welding.DN 15 – 8025 barView product 
T283Clamp Rubber JointFlangeless sleeve clamped onto plain pipe ends — big movement on low-pressure lines.DN 50 – 14001 barView product Compare the Range

Configure to Your Service
OPTIONPTFE LiningA bonded PTFE liner for aggressive chemicals, high-purity or sticky media — chemical resistance without losing the flexibility of the rubber arch.
OPTIONTie RodsAbsorbs the pressure thrust force and prevents the expansion joint from stretching. Keeps your piping and connected equipment free from additional load.
OPTIONControl RodsMaintains the safe movement range of the expansion joint by limiting over-extension and over-compression. Extends bellows life under vibration and sudden pressure changes.Not sure which type or options you need?
