Vent Cleaners

#1 VC Vent Cleaners

Clear & Maintain Tap Holes
Rod Out Pressure Sensing Ports

  • Removes obstructions and prevents blockages in pressure sensing lines
  • Common sizes: 1/4″, 1/2″, 3/4″
  • Fully customizable


Vent Cleaners are used to manually clean out the pressure taps on static (or corner) differential producer type primary flow elements, preventing obstructions of the pressure sensing line(s) between meter and transmitter.


One Vent Cleaner is installed in each piezometer (tap) location. There is no difference between high and low pressure tap vent cleaners for standard HVT-CI (Cast Iron) meters.

Procedure for installation

  • Apply either Teflon tape or pipe compound to threads
  • Insert threaded end into piezometer connection on primary flow element
  • Tighten securely enough to eliminate any leakage, but does not have to be torqued


Seal Assembly
Designed to seal and prevent the leakage of the line fluid.
¾” NPT Cross
Provides attachment points for the pressure sensing lines from transmitter to meter taps.
¾” NPT Plug
Plug is provided in the event the pressure sensing lines are installed opposite the standard location.
½” Stainless Steel Shaft
This rod with “T”-handle is provided to facilitate pushing any accumulated dirt back into the flow stream and away from the pressure sensing lines. Normal rod position is fully withdrawn.
¾” Nipple
The vent cleaner is connected to the taps by means of the threaded end of the nipple.
Isolation ball valve
Allows for isolating the transmitter for maintenance or replacement.
Wastewater, Raw Water, Contaminated Liquid, Potable Water
Common Materials
Carbon Steel, Stainless Steel
Other Available Materials
Aluminum, Zirconium, Hastelloy B & C, Monel, Duplex S/S, Titanium, Tantalum, 321SS, Brass
