Monitoring and regulating pressure is integral to the vacuum bagging process. It can be a simple leak check of a vacuum bagged part or the precise regulation of vacuum for sensitive components. Torr provides a selection of quality gauges and regulators to help our customers monitor and control pressure.

8990471- LIGHTWEIGHT, DRY GAUGE

Range: 0-30" Hg
Size: 2½" dia.
Connection: 1/4 male npt
The 8990471 is an economical, dry vacuum gauge. It has a lightweight ABS plastic case. Accuracy is ±2% of span over middle half of scale and ±3% of span over first and last quarter of scale (3%/2%/3%, grade B).

9767002 - STAINLESS, WET GAUGE

Range: 0-30" Hg
Size: 2½" dia.
Connection: 1/4 male npt
The 9767002 is a rugged glycerin-filled vacuum gauge with a stainless steel case. Accuracy is ±2.5% of span over entire scale. The glycerin helps dampen the effects of vibration and pulsation. It also lubricates the movement, extending the life of the gauge.

9699028 - STAINLESS, LARGE DIAMETER, HIGH-ACCURACY

Range: 0-30" Hg
Size: 4" dia.
Connection: 1/4" male NPT bottom connection
The 9699028 is a larger-diameter version of the 9767002. The 4" diameter face is easy to read and provides higher resolution due to wider gradation spacing.  It's liquid-filled, providing good vibration resistance and an accuracy of ±1% of span over entire scale. Contact Torr for horizontal, panel-mount version.

STAINLESS, HORIZONTAL CONNECTION

This gauge comes in 2 versions. Both have the following specs
Range: 0-30" Hg
Size: 2½" dia.
Connection: 1/4" male NPT, center back
Hole diameter required for panel-mounting: 2.50"
Accuracy is ±2.5% of span over entire scale
Can be installed in panels up to .57" thick using the optional 1327115 bracket

9767185 - "WET" VERSION

The glycerin-filled 9767185 is nearly identical to the the 9767002 but has a center back connection for horizontal mounting applications. The glycerin helps dampen the effects of vibration and pulsation. It also lubricates the movement, extending the life of the gauge.

4270755 - "DRY" VERSION

The 4270755 is a "dry" version of this gauge. For applications where a liquid-filled gauge is not required or where a dry gauge is more appropriate, the 4270755 is an excellent substitute.

9690128 - ABS DRY GAUGE

Range: 0-30" Hg
Size: 1½" dia.
Connection: 1/8 male npt
The 9690128 vacuum gauge is lightweight and compact with a diameter of only 1.6in (41mm). This is a dry vacuum gauge with ABS plastic case and front plastic face. Connection is 1/8” male NPT exiting the center of the back of the case. The dial reads in inches of mercury (inHg). Accuracy is ±2% of span over middle half of scale and ±3% of span over first and last quarter of scale (3%/2%/3%, grade B).

DG25VAC DIGITAL GAUGE

The DG25VAC has a large LCD display that provides instant, accurate feedback for vacuum bag integrity and other processes requiring monitoring. The threaded fitting and case are more robust than the older D1005PS gauge. The large hex fitting helps prevent damage during installation of quick-disconnects and other plumbing components. We not only sell this gauge but we use it every day in actual conditions and it has become the gauge of choice for vacuum leak checks.
