Value Brand Pressure Gauge Liquid Filled 3-1/2 In

3-1/2 Inch Liquid-Filled Pressure Gauge

This commercial pressure gauge is built for industrial and automotive testing where vibration resistance matters. The liquid-filled design steadies the needle on pumps, compressors and hydraulic lines. A 304 stainless steel case and acrylic lens resist corrosion in harsh environments. It suits technicians who need a durable, bottom-mounted instrument with a 1/4 inch NPT male connection.

0 to 400 Range with +/-3-2-3 Percent Accuracy

The gauge reads from zero to 400 on a white dial, using a +/-3-2-3 percent accuracy class across the scale. This tolerance is tightest at mid-range and widens toward the ends, so critical set-points should sit near the centre. The field is not fillable and there is no dry dampening feature, so the liquid fill is the sole vibration control. It handles steady or cycling pressure up to the 400 limit.

1/4 Inch NPT Bottom Connection and IP Limits

The male 1/4 inch NPT thread seals directly into standard ports without adapters. Bottom mounting keeps the dial upright on horizontal pipe runs. The assembly carries no IP or NEMA rating, so it is not certified against dust ingress or water jets. California Proposition 65 warnings apply for chemicals linked to cancer and reproductive harm. Users needing sealed enclosures or higher pressure ranges must select a different model.
