Accuracy (assembly):	±2 PSI (30 PSIG range) ±3 PSI (60 PSIG range)
Accuracy (isolator only):	±1% of maximum operating pressure range
Gauge fluid:	Halocarbon 6.3 oil (Standard fill fluid unless otherwise specified.)
Materials:	Wetted parts are PFA and Kalrez^®. Nonwetted parts include PVDF, Viton^® and 316 stainless steel fasteners.
Pressure range:	1.50" Hg vacuum (50.7 mbar) to 70 PSIG (483 kPa). (For vacuum applications, gauge protector will work better with diaphragm assembled flat rather than inverted towards the media side.)
Temperature range:	75° to 150°F (24° to 66°C), ambient 75° to 250°F (24° to 121°C), fluid
Gauge:	2.5" diameter dial Stainless steel mount, movement and case Safety glass lens 1/4" MNPT mount
Mounting:	Can be mounted using the media pipe connection or by using the two longer 316 stainless steel screws (supplied)

Instructions For Filling Models 217-5 and WGP4-5 With Fluid

WARNlNG: DO NOT disassemble the protector. The protector diaphragm has been pre-stressed at the factory. Disassembly of the upper and lower section of the gauge protector will affect the operation.
When selecting a fill fluid consider the following factors:
•	Fluid should be compatible with the gauge material.
•	Fluid is compatible with the temperature ranges of the fluid being measured and the surrounding environment.
•	Fluid viscosity does not limit the protector response.

1.	Visually check to be sure the diaphragm is pushed toward the fluid port.
2.	Remove the 1/8" plug in the filling port.
3.	Tip the gauge protector such that air will escape during the filling process.
4.	Begin filling the unit with the selected fluid. Periodically tap the gauge protector during the filling process to enable any trapped air to escape. Note that air trapped in the protector will cause indicated gauge pressure reading to be low.
5.	Apply thread sealant or four wraps of PTFE tape to the male threads on the 1/8" plug and re-install, keeping all threads dry. When using PTFE tape, tightly wrap in the direction of the threads to conform tape to shape of threads. Note that gauge fluid on the threads could cause leakage.
