FLEX-SEAL® ARC SHIELDED ADJUSTABLE REPAIR COUPLINGS

DONE RIGHT.
THE FIRST TIME.

Municipal sewer repairs can drain budget resources, disrupt services and snarl traffic. Quick repairs and modifications are only valuable if your system has long-term integrity. FLEX-SEAL® ARC Shielded Adjustable Repair Couplings are the cost effective insurance policy to guarantee repairs.

Applications

Inserting factory-made junctions to existing sewers
Replacing short sections during pipeline repairs
Adapting dissimilar pipe materials and sizes
Joining pipe to manhole connections
Joining short and cut lengths of pipe

RESISTS HEAVY EARTH LOADS

Superior load bearing control between coupling and pipe surface with .012″ thick 301 Series Stainless Steel shield.

KEEPS PIPES ALIGNED

Lock in pipe ends and prevent slippage with rubber sealing “O” rings under each Nut & Bolt clamp.

INSTALLS FAST

Easier to install than elastomeric PVC sleeves, rubber gaskets stay flexible — even in cold weather.

Shielded Adjustable Repair Couplings

FLEX-SEAL® ARC Shielded Adjustable Repair Couplings

UNDERGROUND Installations
Engineered for superior performance, improved alignment and excellent resistance to heavy earth loads, shear forces, and deflection. Connects similar and dissimilar pipe materials and sizes. For non-pressure, gravity flow applications only.
Sizes 1½” to 27″
Custom, large diameter sizes available here.

COMPONENTS

Clamps:
300 Series Stainless Steel, Worm Drive (2)
Surgical Grade 316 Stainless Steel, Nut & Bolt (2 or 4)
Gasket: Molded, One-Piece Elastomeric Sealing Gasket
Shield: Heavy-Duty, 301 Series Stainless Steel (.012″ thick)

FEATURES

LEAKPROOF

Increased band tension secures pipe ends, forming a watertight, root-proof seal, impervious to infiltration and exfiltration.

SECURE

Sealing “O” Rings under each clamp prevent pipe end slippage for a reinforced joint seal.

ANTICORROSIVE

Stainless steel components resist corrosion in marine applications, poorly aerated/moist soils, contaminated grounds conditions, (e.g. industrial fill sites) and chloride, sulfates or bicarbonates in ground water.

RIGID

Thick shear band controls load bearing between coupling and pipe surface, opposing shear forces while maintaining pipe alignment.

ADAPTABLE

Independent clamp tightening adapts to different outside pipe diameters.

DURABLE

Synthetic rubber gasket resists ultraviolet rays, ozone, fungus growth, natural soil erosive properties, and normal sewer gases.

RESILIENT

Synthetic rubbers permit a substantial degree of distortion without change in basic physical resistance. More pliable and easier to install in cold weather applications than an elastomeric PVC gasket.

EASY

MISSIONMADE™ products are easy to install and and reuse.

PRE-CALIBRATED

Installs with a pre-set torque wrench calibrated: 60 in/lbs.

ACCESSORIES

Seekonk Torque Wrench:
60 in/lbs. with .3125″ hex head screw

Unshielded Sewer Couplings

Corrosive environments, earth movement, infiltration and exfiltration occurs without detection of the implications below ground. In these situations, the use of unshielded sewer couplings result in a number of potential problems.

Unshielded sewer couplings allow pipe movement and displacement at the joint, due to heavy earth loads or shear forces under the following circumstances:

Improper backfill or trench beddings
Causes: Contractor error and/or improper bedding material
Soil Expansion or Contraction
Causes: Ground water conditions, flooding, temperature changes, earthquakes, settling soils, etc.
Vibration
Causes: Public transit areas, highways, railroad tracks, airports, etc.

Pipe movement or displacement can cause:

Misaligned, unsecured pipe ends pulling apart.
Result: Leakage at the joint, resulting in infiltration/exfiltration and root infestation
A stepped profile in the sewer line.
Result: Flow obstruction and/or blockage

FLEX-SEAL® ARC Shielded Adjustable Repair Couplings maintain pipe alignment, despite compaction, improper backfill, or soil settling.
