Parker 700132-002 Sight Glass

The Parker 700132-002 is a high-performance PSG-3S moisture liquid indicator designed for commercial refrigeration and HVAC systems. As the direct engineering update to the legacy Parker 070135-02, this unit features a 3/8" ODF solder connection, ensuring a leak-proof fit within the liquid line. Field technicians rely on the PSG series sight glass for its high-visibility sapphire crystal lens, which provides a clear view of the refrigerant's state and moisture levels. The integrated moisture indicator element utilizes a sensitive color-change calibration to detect trace amounts of water, preventing system acidification and compressor failure. Built with a solid brass body, the 700132-002 sight glass is rated for high-pressure R-410A applications as well as common HFC and HCFC refrigerants. This refrigerant liquid indicator is essential for diagnosing charge accuracy and ensuring the filter drier is functioning optimally within the circuit.

Key Benefits:

• Direct Replacement: Seamlessly replaces the discontinued Parker 070135-02 without requiring piping modifications.
• Extended Pressure Rating: High-strength brass construction is compatible with high-pressure refrigerants including R-410A and R-134a.
• Accurate Diagnostics: Large viewing ports allow for immediate identification of flash gas or bubbles in the liquid line.
• Corrosion Resistance: Engineered for durability in demanding mechanical rooms and outdoor environments.
• Precision Sensing: The moisture-sensitive paper provides reliable color transitions at specific PPM levels.

Common Questions:

Is the Parker 700132-002 compatible with POE oils?
Yes, the internal seals and the moisture indicator element are fully compatible with POE, PVE, and mineral oils used in modern HVACR systems.

What does it mean if the sight glass indicator is yellow?
A yellow indication signifies excessive moisture in the system. The filter drier should be replaced immediately to protect the compressor from acid buildup.

Can this unit be installed in any orientation?
For the most accurate refrigerant flow monitoring, the sight glass should be installed in a horizontal run or a vertical-up position on the liquid line.
