Glycerin Filled Vacuum Gauge by Uharbour 2.5″ Clear Dial Stainless

Description

Product Overview

The Uharbour Glycerin Filled Vacuum Gauge is engineered for demanding environments where accuracy and durability are non‑negotiable. Featuring a 2.5″ clear dial, the instrument provides an unobstructed view of pressure readings, allowing operators to quickly assess vacuum levels without guesswork. The gauge is housed in a stainless steel case that resists corrosion, dents, and impact, extending service life far beyond standard steel or plastic enclosures. Inside, brass wetted parts ensure consistent performance over a wide temperature range, while the glycerin filling damps vibration and pulsation, delivering steady, repeatable measurements even on noisy machinery.

Technical specifications include a 1/4″ NPT bottom connection for straightforward mounting on compressors, vacuum pumps, and test rigs. The gauge offers dual scales ranging from -30 inHg to 30 PSI, covering both vacuum and low‑pressure applications. Its compact dimensions—3.5 x 2.7 x 1.2 inches—and lightweight design (6.24 ounces) make it easy to integrate into tight spaces without sacrificing readability.

Usage

Designed for versatility, this gauge excels in a variety of settings. In industrial plants, it monitors vacuum levels in drying ovens, coating lines, and material handling systems, ensuring processes stay within optimal parameters. Laboratory technicians rely on its precise readings for research involving gas chromatography, vacuum distillation, and material testing, where even minor pressure fluctuations can affect results. HVAC professionals use the gauge to verify system evacuation and leak detection, while automotive workshops appreciate its ability to check brake booster vacuum and engine intake manifold pressure.

Because the gauge is glycerin filled, it tolerates harsh vibration from compressors and pumps, making it ideal for mobile applications such as field service units, portable vacuum generators, and on‑site equipment diagnostics. The stainless steel case also protects the instrument from chemical exposure, allowing safe use around solvents, acids, and other aggressive substances commonly encountered in manufacturing and laboratory environments.

FAQ

What is the measurement range of this gauge?

The gauge covers a dual range of -30 inHg (vacuum) to 30 PSI (positive pressure), suitable for most low‑pressure and vacuum applications.

Can this gauge be used with corrosive gases?

Yes. The stainless steel case and brass internal components are resistant to many chemicals, making the gauge safe for use with most non‑halogenated corrosive gases.

How do I install the gauge on my equipment?

Simply thread the 1/4″ NPT bottom connection into the corresponding port on your compressor or vacuum pump. For added security, you may apply Teflon tape to the threads before installation.

Is calibration required?

The gauge is calibrated at the factory to meet ASME standards. Routine checks are recommended annually, but most users find the instrument remains accurate for years without recalibration.

What warranty does Uharbour provide?

Uharbour offers a lifetime satisfaction guarantee, covering defects in materials and workmanship. Our support team is available to assist with any issues you may encounter.
