- Mission HeavyWeight No Hub Coupling, Heavy Duty, Fitting/Connector Type: Coupling, 4" Nominal Size, Cast Iron, Stainless Steel, Domestic
- 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/lb
- 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 to 4 in sizes for four stainless steel bands and 5 to 15 in sizes for 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
- Multiple bands attached to heavy duty, corrugated 304 series stainless steel shield over a molded one-piece elastomer sealing sleeve
- Sealing rings on flanged neoprene rubber gasket meet or exceed the requirements of ASTM C 564
- Axially slotted heavy duty worm drive clamps tightened to 80 in/lbs of torque
- 3 in W
