    1/4" Female x 1/2" Male (NPT)  Natural Polypropylene With 2" Steel Case / Brass Connection

    • 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.

    Plast-O-Matic differential pressure gauges are designed to measure the difference in pressure between two points in a system and present the resultant differential pressure directly on a single gauge dial. A magnetic movement allows the simultaneous sensing of both pressure points, while completely isolating the gauge function from the pressure chamber. No mechanical seals are required. Each of these devices are engineered for durability and performance. Maximum line pressure rating is 200 PSI.

    Plast-O-Matic flow gauges indicate liquid flow rates from low flows of 0-1 GPM to 0-10 GPM, even when used at high line pressures. Flow gauge sensors can be supplied with switches or relays to initiate alarms, activate other equipment, or shut the system down. Two switches are used when high and low limits are desired. Maximum line pressure rating is 200 PSI.
