Heavy-Duty, shielded couplings connect Cast Iron hub less soil pipe and fittings in sanitary and drain waste and vent (DWV) applications. For non-pressure, gravity flow applications only. Recommended for above and underground installations. Easy to install and reuse.
For heavy-duty installations requiring more than a standard No Hub coupling
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/lbsStronger, 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 joinedGreater 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
- 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
