Product Description

Universal coupling
Enables the mechanical jointing of pipes made of different materials and of various outside diameters

Description
Wide outside diameter range: an average of 29 mm.

High performance
- Permanent leak tight joint when compressing the gasket between the end ring and the sleeve onto the pipe surface
- Epoxy powder coating (250 μm) and Geomet® 500 Gr. B for the bolts.

Ease and speed of installation:
- Angular deflection ± 5° by side.
- Absorbs expansion and contraction.
- Accommodates misalignment.
- Important setting gap.

Conformity to standards
- EN 14525 : Ductile iron wide tolerance couplings and flange adaptors for use with pipes of different materials: ductile iron, Grey iron, Steel, PVC-U, PE, Fiber-cement.
- NF A 48-830: Foundry products - Spheroidal graphite cast iron fittings for PVC drinking water pipes under pressure,
- EN 545: Ductile iron pipes, fittings, accessories and their joints for water pipelines 
- requirements and test methods,
- ISO 2531: Ductile iron pipes, fittings, and accessories and their joints for water applications.

Approval:- Drinking water approved (WRAS).

Note:
- This coupling does not resist to longitudinal forces and pipe pullout will occur. Ensure adequate restraint is provided.
- Not recommended for PE pipes.
