SPAN Liquid Filled Pressure Gauges

Only SPAN Pressure Gauges offer these unique features.

• ZYTEL NYLON CASE: Tough, corrosion resistant, impact resistant, weather resistant, Zytel nylon case. Over 13,000 ld tensile strength. Removable bezel design allows repair or recalibration.

• ALL SIZES MATCH: All SPAN 2 1/2", 3 1/2", and 4 1/2" stem and panel mounting cases are uniform and match in appearance.

• "NO BUBBLE": The Internal "breathing diaphragm" eliminates the need for an air bubble in the midrange of the gauge, which could distort readings and looks unsightly. The ICD is standard on some 2 1/2" and all 3 1/2" and 4 1/2" models. (Available as an option when not standard.)

• TEMPERATURE COMPENSATED: The ICD compensates the case (to 150 deg. F), for changes in internal case pressure caused by fluctuations in ambient temperature. (Especially important in lower pressure and vacuum gauges.)

• LARGER DIAL: Because the American Made SPAN is built to ANSI/ASME B40 Standards, our dial is 2.5". (Our imported competitors measure 2.5" case not dial.) View the difference yourself. This is the easiest reading 2 1/2" gauge model.

• FREEZE PROOF: An internal diaphragm seal to prevent freezing, clogging and corrosion is available on all SPAN gauges.

• SPECIALS: Custom dials, logos, stainless steel bezels and specially manufactured instrumentation are available.

• NON-YELLOWING GLYCERIN FILL: Standard fill: non-yellowing, crystal clear glycerin (interlube) for temperatures -40 deg to 150 deg F. For ranges below 30 PSI used below -10 deg F, specify 70-30 glycerin.
