Key Features
- Coupling has a slotted shield design to compensate for mismatched pipe/fitting diameters; maintains alignment
- Coupling has a unique flexible rigidity™ to withstand high thrusts or blockage pressure on mismatched pipes and fittings
- Slotted shield of coupling is made of 28 gauge 304 18-8 chromium nickel stainless steel; corrosion resistant
- Neoprene gasket features two sets of sealing beads on each sealing sleeve for easy installation and stability
- Hubless coupling has worm drive clamps made of 304 stainless steel with screws made of 305 stainless steel
Applications
- Ideal for storm and sanitary DWV systems in high-risk environments – schools, hospitals, museums or wherever a 15 PSI rating is required
- Suitable for waste and vent piping applications
- As part of a complete flow management system, the hubless coupling connects two cast iron pipe and fittings up to 15 PSI, together to allow water to flow through while preventing leaks
Materials & Sustainability
- Hubless coupling is made of 24 gauge 304 18-8 chromium nickel stainless steel
- Gasket is made of neoprene; worm drive screws are made of 305 stainless steel
- Made in USA of domestic materials
- Onsite flow management protects pipe systems from leaks which can lead to corrosion of pipes, property damage, and issues with the flow system
Installation
- Coupling slides onto connection point between two DWV pipes;
- Tighten screws using a torque wrench (sold separately) to a full 125 lbs. or 80 lbs. of torque to secure in place;
- Interlocking design centers sleeve within housing for easy installation and stability
Maintenance
- Hubless coupling performance issues can indicate damage; replace as needed
