Economy Low Pressure Test Plug

For Low Pressure Testing Of Pipe and Tubing


  • Pressures to 35 psi (2.4 Bar)*
  • Sizes for 3/8" to 4" (9.5mm - 101.6mm) Pipe and Tube I.D.

EST's Economy Low Pressure Test Plugs are designed for simple, reliable testing of pipe and tubing, without the tube wall damage associated with other test plugs. That's because our Economy Plugs feature a neoprene seal - the only part of the plug that comes in contact with the tube I.D. Simply install the Economy Test Plug into the open end of a pipe or tube. Tighten the wing nut (2" to 4" sizes use a hex nut) to expand the seal. Begin pressure testing.

*Note: Maximum operating pressures have been determined by testing performed in clean, dry commercial grade carbon steel pipe. For maximum operating pressure in other applications, contact EST directly.
