Applications of No Hub Couplings

B2B buyers source no hub couplings for these primary application areas. Each has specific code, material, and performance requirements we fully support.

  • Commercial Plumbing & DWV Systems

Connecting cast iron soil pipe for drain, waste, and vent stacks in commercial buildings. No hub couplings replace traditional lead-and-oakum hub joints, dramatically reducing labour time.

  • Residential Plumbing

Above-ground and below-slab drainage in housing developments. Standard-duty couplings are the code-preferred joining method for hubless cast iron pipe under all major plumbing codes.

  • Stormwater & Underground Drainage

Heavy-duty couplings handle the mechanical loads and pressure cycles found in underground storm drainage and municipal infrastructure. Corrosion-resistant SS shields withstand soil chemicals.

  • Industrial Facilities

Chemical plants, processing facilities, and industrial drainage where fluid resistance and vibration dampening are critical. EPDM gasket options provide enhanced chemical resistance.

  • Repair & Rehabilitation

Ideal for replacing damaged sections of existing cast iron pipe without disturbing the surrounding system. No hub couplings allow section-by-section replacement in occupied buildings.

  • Export & Distribution

We supply wholesalers, hardware distributors, and plumbing material traders globally. All products are export-packed, with documentation for customs clearance and import compliance.

Frequently Asked Questions

Common questions from plumbing distributors, hardware wholesalers, and project procurement teams.

  • What is a no hub coupling used for?
    A no hub coupling connects sections of cast iron soil pipe and fittings in drain, waste, and vent (DWV) plumbing systems. It replaces the traditional hub-and-spigot joint, allowing faster installation without the need for lead and oakum caulking. They are used in residential plumbing, commercial buildings, and underground drainage systems.What is the difference between standard, medium-duty, and heavy-duty no hub couplings?
    Standard duty (CISPI 310 / ASTM C1277) suits most residential and general commercial applications with 60 in-lbs torque. Medium duty (ASTM C1540 / FM 1680) uses 80 in-lbs torque and is identified by a yellow shield — required for elevated mechanical loads and certain commercial codes. Heavy duty also uses 80+ in-lbs torque with a thicker SS band and green shield, specified for high-rise, underground, and seismic applications or where NYC/Massachusetts codes apply.
  • What is the minimum order quantity (MOQ) for wholesale buyers?
    MOQ varies by product type and size. For standard in-stock items, we accept trial orders to help new customers evaluate quality. Volume discounts start from container-load quantities. Custom OEM orders have their own MOQ depending on tooling requirements. Please contact us with your target quantity and we’ll provide a tailored quotation.
  • Do your no hub couplings comply with US plumbing codes?
    Yes. Our no hub couplings are manufactured to conform to CISPI 310 and comply with ASTM C1277 (standard) and ASTM C1540 (medium/heavy duty). Medium and heavy duty products also comply with Factory Mutual 1680 and IAPMO listing requirements. We supply test reports and conformance documentation. For New York City projects, our heavy-duty couplings comply with MEA 253-98-E.
  • Can you produce no hub couplings with custom sizes or private-label packaging?
    Yes. Our R&D team accepts customer drawings, samples, and specifications to produce non-standard sizes. Private-label packaging with your brand name, logo, and barcode is available for distributors. Lead time for custom orders depends on tooling requirements; typical first-sample lead time is 15–25 working days after drawing confirmation.
  • What material is the gasket made from?
    Standard gaskets are manufactured from 100% neoprene complying with ASTM C564. EPDM gaskets are also available for applications requiring higher chemical resistance or UV/ozone exposure. Please specify your gasket material requirement when requesting a quotation.
  • What is your typical lead time and delivery arrangement?
    Standard products from stock ship within 7–15 days. Made-to-order standard items are typically 20–35 days depending on volume. We ship via sea freight (FCL/LCL), air freight, or express courier depending on order size and urgency. Export documentation (commercial invoice, packing list, certificate of origin, material certificates) is provided with every shipment.
