Operating Instructions

Standard Seal Material: U = Urethane, N = Neoprene, U/N = Dual Urethane / Neoprene material
NOTE: M Suffix plugs hold in plastics, FRP and Stainless Steel

High Pressure Test Plugs use the test pressure to help seal more securely against the pipe's inner diameter

Typical Applications: Force and water main, lift stations, nuclear cooling lines, fire protection lines, special plant situations, irrigation supply lines, and many other projects. See important notes at page bottom.


Typical multiple and single shaft configurations

IMPORTANT:

  • M = Male NPT, F = Female NPT
  • NEVER use a test pressure greater than the weakest component in the system can handle. Test Pressure specified in table is equivalent to 80% of the pressure that will yield ASTM A106 Grade B pipe. The test pressure for higher and lower strength pipes will differ proportionally. The maximum test pressure for higher strength pipe must never exceed the highest test pressure listed for that pipe O.D.
  • Sizes that do not have a test pressure listed differ from standard pipe sizes. These plug sizes are normally used to test tubing. For use of these plug sizes in tubing with a minimum yield strength of 35ksi, the maximum test pressure is estimated by the test pressure listed for the equivalent or next larger pipe O.D. with the equivalent or next thinner wall thickness. The test pressure for higher and lower strength tubes will differ proportionally. The maximum test pressure for higher strength tubes must never exceed the highest test pressure listed for the equivalent or next larger pipe size. NEVER use a test pressure greater than the weakest component in the system can safely handle.
  • Standard Seal Material: U = Urethane, N = Neoprene
  • These plugs were designed to operate in A106 grade B pipe with a hardness up to 20 on the Rockwell C scale (HRC 20). Plugs may be customized for hardness to HRC 25. Plugs for other hardness ratings require a customers pipe sample and further pressure testing.
