1/4" FNPT 316 SS Lock-On Gauge Probe 1/2" FNPT 316 SS Lock-On Gauge Probe

The small area of the stainless needle means that only a 6 lb. push per 1,000 psi in the system is required to force the probe into the Gauge Plug and open the valve. Lock-On-Probes are recommended where the pressure or sample device is to be mounted onto the Gauge Plug or where the rpessure on the Gauge Plug exceeds 5,000 psi.

Applications

• Troubleshoot complicated hydraulic or pneumatic circuits during operation without breaking pressure in lines.
• Sample line fluids in seconds.
• Gauge corrosive fluids or sour gas with safety.
• Read pressures and take samples on reverse osmosis systems.
• Take pressures on waterflood injection systems.
• Take pressure on ammonia or steam lines.
• Calibrate or test the accuracy of fixed pressure gauges or meters.
• Check filter pressure differential.

Advantages of the Gauge Plug & Probe System

• Seal is bubble tight.
• Metal to metal seat plus elastomer seal.
• All Stainless Steel construction.
• Probe on, take a reading and probe off in seconds.
• Screen filters debris which eliminates potential clogs.
• Unique design moving slots past o-rings prevents seal damage.
• The zero of the pressure gauge can be checked before and after probing is on.
• The probe needle does not have to be lubricated prior to probing.
• Reduces cost of gauge loss due to theft or vandalism.
• Eliminates excessive wear on expensive, delicate gauges due to harsh environments, vibration, pressure pulsation or mechanical shock.
