Plast-O-Matic GGTS030-PF gauge guard is designed to separate and safeguard pressure or vacuum instruments used on extremely pure or highly corrosive fluid lines. It can be used with liquids like sulphuric acid, caustics, demineralised water and hydrochloric acid.
Features:
- Plast-O-Matic GGTS030-PF gauge guard features a stainless steel hex insert to minimise breakage due to overtightening.
- It does not expose top metal fasteners and reduces system downtime & system failure.
- The robust and flexible diaphragm of the unit acts as a barrier between the instrument and the process fluid.
- To correctly convey the process pressure to the instrument, the internal space on the diaphragm's instrument side needs to be securely filled with an appropriate liquid.
- Its outstanding diaphragm sensitivity to small changes in pressure or vacuum is the consequence of excellent flexing properties and a sizable sensing surface (2.07 square inches).

Frequently Asked Questions:
Q. What are the important points to remember while installing a gauge?
A. Any threaded gauge, transducer or a pressure switch can be inserted. However, before assembly, the user-supplied device should be examined for O-ring seal leaks. The gauge will seal on the O-ring if you don't apply a thread sealant or tape on it.
Q. How to install this Plast-O-Matic gauge guard?
A.
- Put the O-ring within the guard. Fill the guard with liquid until it is about halfway up the threads.
- To get rid of bubbles, tilt and gently tap the guard. (A little air that has been trapped is okay.)
- Use as much gas as you can in the gauge. To remove the bubbles, use a tiny wire or needle.
- The gauge should be finger-tightened. Once the gauge bottoms out on the stainless steel insert, formed into the guard body, O-rings should be compressed. Avoid overtightening and 10 to 30 inch pounds (1 to 3 Nm) of torque is sufficient. Tighten the process side to position the gauge so that it faces "Forward."
- Remove the gauge guard from the process side and drain the process fluid if the gauge does not read zero after following the gauge installation method. Hand tighten the gauge to create the seal while applying pressure to the diaphragm.
- Follow the same steps and somewhat forcefully press the diaphragm if the gauge still does not register zero. When the gauge reaches zero, reconnect to the process line.
- Remove any leftovers, then add alcohol to the liquid.
