Description

A gland-type loose sleeve expansion joint composed of a loose sleeve telescopic joint and two spacing short pipes, designed to connect pipes of different materials and outside diameters. Manufactured from ductile iron with anti-corrosion epoxy coating, it accommodates axial displacement and misaligned or dissimilar pipelines. Sealing is achieved via EPDM or NBR gaskets secured with steel bolts.
