  • Patented bi-directional shield Design: the shield adjusts to a variety of a pipes diameters and circumferences-eliminating leak paths, the patented, bi-directional corrugation shield seals pressure in both parallel and transverse patterns on the gasket and pipe to provide a positive, reliable seal
  • Specially beaded Gasket: Meeting the requirements of ASTM C564, the beaded gasket consists of an elastomeric compound with strategically positioned grooves and beads, when tightened, the shield attaches to the grooves to provide exceptional sealing pressure and holding power
  • Interlocking clamp Design: the clamps feature a one-piece screw housing that mechanically interlocks to the band, this design eliminates leak paths that can occur in staked or welded clamps
  • Floating Eyelet Design: Fastenting the clampes to the shield, the floating eyelets allow the clamp, band and shield to move independently, this freedom prevents the shield from crimping and future leakage
  • The distinctive green shield quickly identifies the heavy duty couplings and makes it easier for inspectors
  • 3/8 in hex head screw applies 80 in lb of installation torque to the band/shield assembly
  • Boasts an ultimate torque rating exceeding 100 in lb and heavier gauge stainless steel
  • Couplings conform to CISPI 310, factory Mutual EN 1680, couplings comply with ASTM C564, ASTM C1540, IAPMO file #3198, Commonwealth of Massachusetts CMR-248 and City of new York MEA 253-98-E
  • Gaskets are made from an elastomeric compound that meets the requirements of ASTM C564
