Coliter®’s expansion joints absorb thermal expansion, vibration, and misalignment in water, HVAC, fire protection, and industrial piping systems. The series includes the KXT rubber flexible joint (single/double sphere) with EPDM/NBR inner liners for noise and shock reduction, the B2F double flange limit expansion joint that restricts axial movement while allowing angular deflection, and the SS metal bellows expansion joint for high-temperature steam or corrosive media. Available in flanged or threaded connections (DN25–DN3000), rated at PN6–PN25, and compliant with GB/T 12465 and ISO standards, these joints protect pumps, valves, and supports from stress damage—ensuring system integrity, leak-free operation, and extended service life.
