Pipe Couplings
Ductile iron flexible couplings that connect plain-end ductile iron pipes while accommodating limited axial movement, angular deflection and minor misalignment. EPDM sealing rings are compressed between the GGG50 middle sleeve and end gland rings, creating a secure, leak-resistant joint without welding or flanged pipe ends.

Questions & Answers
What is a ductile iron pipe coupling?
A pipe coupling joins two plain-end pipes with a ductile iron middle sleeve and two end gland rings that compress EPDM sealing rings onto the pipe surface. It needs no welding or flanged ends and allows limited axial movement, angular deflection and minor misalignment.
Is this the same as a Dresser coupling?
It is the same type of connection — a gland-and-sleeve flexible coupling for plain-end pipe, often referred to generically by that trade name. Ours is ductile iron GGG50 to ISO 2531 and BS EN 545, epoxy coated 250-300 µm, in DN80 to DN1600.
What size range do you supply for pipe couplings?
DN80–DN1600. Other sizes can usually be supplied on request — send your requirement for confirmation.
Is a technical datasheet available?
Yes — the official YTM Pipe datasheet with dimensions, materials and standards can be downloaded on this page.
