Put Furmanite to the test on your next Hot Tapping or Line Stopping project and you will see why experience counts and why WE WORK BEST – UNDER PRESSURE.


Non-Reinforced Hot Tap and Line Stop Nozzles or “Nipples” are perfect for branch connections into low pressure or in many reduced branch applications. Hot Tap Nozzles provide an economical means for making Hot Taps and Line Stops in applications where full encirclement split tee fittings are unnecessary. Reinforcing Pads, Reinforcing Saddles, or Reinforcing Split Sleeves can provide additional pipe reinforcement when used in conjunction with the Nozzle style tapping fitting.


Furmanite provides a complete line of High and Low pressure Split Mechanical Bolted Hot Tapping and Line Stop fittings and sleeves. The Bolt-On style of Fitting are utilized in situations where welding is either not an option or is too hazardous to perform. The Split Sleeve Mechanical Hot Tap fitting and Split Sleeve mechanical Line Stop fitting are available in a variety of configurations. Common options include gripper rings, hinge plates, sealant injection ports, special coatings, and remote installation prep for sub-sea Hot Tap applications.
