This dedicated coupling for ductile iron pipe PN10/16 connects DI plain ends with a purpose-designed OD range — reducing installation risk versus wide-range couplings when pipe material is known. Future Maker manufactures for European utility and industrial supply chains.
Complements our restrained and universal coupling range with clear specification data. Request pricing and availability.
Frequently asked questions
When should I use a dedicated DI coupling instead of a universal coupling?
Use a dedicated DI coupling when the pipe material and OD are known ductile iron. Universal couplings suit mixed materials; dedicated designs optimise sealing for DI OD ranges.
Is it rated PN10/PN16?
Yes. Match the coupling rating to your system design pressure and do not exceed published limits.
Can I order this with restrained HDPE couplings on one PO?
Yes. Submit a combined couplings BOM for consolidated B2B quotation and logistics.
