Robinair Low-Side Compound Replacement Gauge 11794 — White-on-Blue Dial, Brass NPT, Lexan Lens

The Robinair 11794 is a universal low-side compound refrigeration and A/C service gauge that reads PSI, kPa and shows R‑22 and R‑134a temperature equivalents on a clear, durable dial.

This compact replacement gauge updates the older No. 11692 model with a modern white-on-blue/black display, a rugged Lexan lens and a brass NPT fitting for reliable field service. Designed for HVAC‑R and automotive technicians, it provides both pressure and refrigerant-temperature reference so you can interpret system conditions quickly without switching instruments.

How does the 11794 display pressure and temperature information?

The gauge face combines dual pressure scales with refrigerant temperature markings so you can read system vacuum/pressure and see corresponding saturation temps for R‑22 and R‑134a at a glance. The color-contrasted dial improves visibility in shop lighting while the compound function shows both vacuum and positive pressure.

• Pressure shown in PSI and kPa for broad compatibility.
• R‑22 and R‑134a temperature columns in degrees Fahrenheit.
• White numerals on blue/black background for quick legibility.
• Compound range covers vacuum and positive pressures used in service.

Is the 11794 compatible with my existing hoses and ports?

The gauge uses a standard brass NPT fitting, making it a drop‑in replacement for many low‑side service applications and existing manifolds or hose assemblies that accept NPT. It was engineered as a modern substitute for Robinair No. 11692, streamlining upgrades without changing service procedures.

• Standard brass NPT connection for common hose fittings.
• Designed to replace Robinair 11692 without adapter changes.
• Works with R‑22 and R‑134a service routines when paired with proper hoses.

What construction features help the gauge handle shop use?

Built to endure everyday service, the 11794 combines a Lexan lens with a brass fitting to resist impact and corrosion. The dial mechanics are tuned for consistent readings under vibration and temperature swings common in field service environments.

• Rugged Lexan lens resists cracking and scratching.
• Brass NPT fitting for durability and leak resistance.
• Robust internal movement for reliable, repeatable readings.

Why choose this gauge over older replacement models?

The 11794 modernizes an established replacement option by improving readability and maintaining universal service compatibility. It keeps the simplicity technicians expect while updating materials and presentation for faster interpretation and longer life in demanding use.

• Contemporary dial layout for speedier diagnosis.
• Direct replacement for prior Robinair 11692 model.
• Trusted brand heritage from Robinair, a Bosch Automotive Service Solutions company.

Who is this for: technicians, service shops and mobile mechanics who need a dependable low‑side compound gauge that reads both pressure and refrigerant temperatures for R‑22 and R‑134a. If you perform HVAC‑R or automotive A/C diagnostics and want a rugged, easy‑to‑read replacement gauge with standard NPT compatibility, the Robinair 11794 is designed for your toolbox.
