  • 300 Series stainless steel shear rings with a minimum thickness of .012" conform to ASTM A 240
  • 316 Series stainless steel clamps with nut and bolt takeup are standard and meet all requirements of ASTM A 240
  • Mission's ARC stainless steel shear ring is the heaviest in the industry; over 33% thicker than the competition
  • Molded rubber sleeve, extruded in larger sizes, conforms to ASTM C 425, ASTM C 1173
  • Most couplings require no bushings for dissimilar types or sizes of pipe
  • Nut and bolt clamp design is much stronger than traditional worm drive design
  • Sealing "O" rings under each sealing clamp band prevent pipe slippage and provide a more positive seal
  • Surgical Grade 316 stainless steel sealing clamps provide the greatest corrosion resistance possible
