- More effective joint movement restraint
- Stainless steel strap bands are 12.5% thicker than on traditional no hub
couplings providing a positive seal when properly torqued to 80 in/lbs
- Stronger, more uniform scaling capacity
- Axially slotted clamp bands tighten independently to accommodate most
any variances in outside diameters of cast iron pipe and fittings being joined
- Greater surface load bearing
- Wider 304 Series stainless steel shield accommodates additional sealing
clamps to provide for greater load bearing contact
1-1/2" - 4" sizes: Four stainless steel bands
5" - 15" sizes: Six stainless steel bands
- Higher resistance to shear forces
- Rugged construction, excellent sealing properties and the arrangement
of intermittent corrugations in the outer stainless steel band provide
resistance to shear forces and help alignment while maintaining flexibility
- Corrosion resistant
- 304 Series stainless steel combined with significant deflection factor makes
this coupling highly dependable above and below ground
- Safe and easy to install
- Flanged gasket helps maintain alignment during installation and tapered ends
on shield reduce friction and prevent injury from sharp edges
- Versatile
- Internal profile of elastomeric sleeve against intermittent corrugation
suits specific performance application of non-potable waste systems
