SHORTSTOPP® Bolt-on Fittings

Bolt on Fitting

SHORTSTOPP® bolt-on fittings can be used with TDW tapping machines or SHORTSTOPP plugging machines to perform tie-ins, lateral connections, extensions, crossovers, repairs, and main relocations without pipeline shutdown.

The fittings are highly versatile and suitable with a wide range of pipe materials, including steel, ductile iron, and cast iron. They have a maximum working pressure of 4 bar (60 psi) at 51°C (150°F) and meet ASME B31.8 standards.

SHORTSTOPP bolt-on fittings are available in sizes 2 inches through 12 inches (larger sizes are available upon request). The 2-inch and 3-inch versions have threaded connections and are made of ASTM A-106 Grade B steel, while the 4-inch through 12-inch versions use a flange adapter and can be made of ASTM A-105 if required.

Key features:

  • Fitting package includes top half, bottom half, bolts, nuts, O-ring seals, gaskets, completion plug, and blind flange or cap.
  • 4-inch through 12-inch versions can accommodate TDW SHORTCUTT® valves.
  • Can be supplied in a top seal or circumferential end seal design for the fitting-to-main attachment.
