New Miniature Thermoplastic Diaphragm Seals
& Gauge Guards

Protect Your Pressure or Vacuum Instruments From Clogging, Corrosion and Damage!

Features and Advantages:

Diaphragm Seal, instrument isolator, Gauge Guard...no matter what you prefer to call it, this device provides an excellent and important protective barrier between process fluid and the pressure/vacuum gauge or instrument.
Increase product reliability and reduce system downtime caused by failure of instruments not protected by seals.
Exceptionally low unit cost - now makes it feasible to protect even moderate priced instruments.
Compact size makes these isolators ideal for limited-space installations.
Liquid pressures to 200 psi with +-4% accuracy. Choice of Buna-N or FKM (Viton) seal will handle most applications.
Use with gauges, transducers, and pressure switches.
Simple to fill and install.
Hermetically-sealed uni-body construction - molded body avoids possibility of dangerous leaks.
For use with highly aggressive or ultra-pure liquids.
Diaphragm safety - If the gauge or instrument fractures or is removed from the guard while the system is pressurized, the diaphragm will automatically seal against leakage to the atmosphere.
Polypropylene bodies for excellent chemical compatibility and temperatures to 185° F (85° C). The upper half (instrument side) is glass-filled polypropylene; the lower half (process side) is 100% natural, unpigmented virgin polypropylene.

Series GGM this is the full-sized gauge guard. In most applications, this larger unit is unecessary, but the fact that it is offered in a variety of plastics -- including a plastic diaphragm -- makes it better suited for certain applications. In addition, the GGM diaphragm seal is offered with a special acrylic gauge shield, which is essential in harsh chemical environments.

Series GGMU this is the high-purity, zero deadleg gauge guard.
