Universal Coupling

The gland type loose sleeve expansion joint is composed of loose sleeve telescopic joint and two spacing short pipes. It is mainly used to absorb the axial displacement and loose pipe connection under axial pressure and thrust in the allowable displacement range.

Product Description

Description

The Universal Coupling is a versatile and easy-to-install solution designed to connect pipes of different materials and outside diameters. With a flexible design and wide tolerance range, this coupling ensures a secure, leak-proof joint even when connecting misaligned or dissimilar pipelines.
Manufactured from high-strength ductile iron and coated with anti-corrosion epoxy, the universal coupling is suitable for both underground and above-ground applications. Its robust sealing system, including EPDM or NBR gaskets and stainless steel bolts, ensures excellent performance under varying pressure and temperature conditions.

Ideal for municipal water supply, sewage systems, irrigation networks, and industrial pipelines, the universal coupling helps simplify pipeline repair and maintenance by providing flexibility and quick installation without welding or threading.

As one of China’s leading valve and pipe fitting manufacturers, we deliver reliable, field-proven products for engineering projects worldwide. Our universal couplings are available in a range of diameters and pressure ratings, and meet international standards like ISO 2531 and EN 14525.

Whether for new installation or emergency repairs, our universal coupling offers strong, adaptable, and long-lasting pipe connectivity.
