Features:

·   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

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

Accelerated Aging:

·   15% max. tensile and 20% max. elongation deterioration.10 pts. max. increase in hardness. All determinations after oven aging for 96 hrs. at 158°F.

Ozone Cracking:

·   No visible cracking at 2X magnification of the gasket after 100 hrs. exposure in 1.5 PPM ozone concentration at 100°F testing and inspection to be on gasket which is loop-mounted to give approx. 20% elongation of outer surface.
