Ashcroft 93759XLL Pressure Gauge 4.5 in Dial Rear Flange 30-0-60 Psi

Product Description

The ASHCROFT 93759XLL is an analog pressure gauge designed for accurate pressure monitoring across a compound range of 30 to 0 to 60 psi. It features a 4.5-inch dial for clear readability and is housed in an aluminum case with stainless steel wetted parts for durability in demanding service environments. The gauge mounts via a rear flange configuration with a 1/4-inch thread connection. Accuracy is rated at 0.5 percent of scale, making it suitable for applications where reliable pressure readings are required. This gauge is a non-liquid-filled unit. Licensed HVAC technicians, plumbers, and industrial maintenance professionals are the typical end users.

This gauge is well suited for use in HVAC systems, plumbing installations, and general industrial or mechanical service applications where a compound pressure range is needed. The compound scale allows the gauge to read both vacuum and positive pressure, which is useful in refrigeration suction lines, fluid systems, and low-pressure gas monitoring setups. The rear flange mount style allows for panel or wall-surface mounting in control cabinets or equipment enclosures.

Key Features

• Compound pressure range: 30 to 0 to 60 psi — reads both vacuum and positive pressure
• 4.5-inch analog dial for high visibility in field and panel applications
• Stainless steel wetted parts for corrosion resistance in wet or chemical-contact service
• Aluminum case construction — lightweight and durable
• Rear flange mount with 1/4-inch thread connection for panel or surface installation
• Non-liquid-filled design — no silicone or glycerin fill
• 0.5 percent of scale accuracy for reliable process monitoring

Compatibility

Designed as an OEM-style or replacement analog pressure gauge for HVAC, plumbing, and general mechanical systems requiring a compound psi range with rear flange panel mounting.

Installation Notes

Installation should be performed by a qualified technician. Shut off and fully depressurize the system before removing or installing any pressure gauge. Use appropriate thread sealant compatible with the system media on the 1/4-inch threaded connection, and avoid overtightening to prevent case or fitting damage. Follow applicable local codes, including ASME B40.100 guidelines for pressure gauge installation and application.
