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.

4240511 - "DRY" VERSION

The 4240511 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 4240511 is an excellent substitute.

D1005PS DIGITAL GAUGE

The digital display on this gauge is instant and accurate, and gives you an indication of the vacuum decay. After you use it a few times, you'll be able to use the hundreths of an inch digit to determine if your leak rate is acceptable or not. Having this type of accuracy provides instant feedback.

490200 VACUUM REGULATOR

The 490200 provides precise, efficient regulation of vacuum processes.
Instead of using air bleed to adjust vacuum level, the 490200 uses a combination of diaphragms and springs, much like a conventional positive pressure regulator.
A vacuum source is connected to the 1/4" female NPT "VAC" port and the line you wish to regulate is connected to the "SET" port on the opposite side.
There are two 1/8" female NPT gauge ports (gauge optional). The regulator comes with a panel nut so it can be installed in panels up to .20 in. thick using a 1.50 in. dia. hole. A small notch needs to be cut for the anti-rotation bump.
