Sporlan 761703 Moisture Liquid Indicator Sight Glass

Product Description

The SPORLAN 761703 is a See-All series moisture and liquid indicator designed for use in refrigerant liquid lines. It combines moisture indication and liquid-level sight glass functions into a single compact unit. A color-sensitive porous filter element changes from dark green to yellow as moisture levels rise above safe operating thresholds, giving technicians an immediate visual read on refrigerant dryness. The clear sight glass also allows the tech to confirm proper refrigerant flow to the expansion device. Every unit is factory leak-tested before shipment.

This indicator installs in the liquid line of a refrigeration or air conditioning system, upstream of the expansion valve or TXV. It is used in residential and light commercial refrigerant circuits where quick visual confirmation of moisture content and liquid line charge condition is needed. Licensed HVAC-R technicians and refrigeration mechanics are the primary installers.

Key Features

• Dual-function design combines moisture indication and liquid sight glass in one unit
• Color-coded moisture element: dark green indicates dry refrigerant, yellow indicates moisture present
• Element calibrated to change at moisture levels within the generally accepted safe operating range
• Clear sight glass allows visual confirmation of proper liquid flow to the expansion device
• Factory leak-tested for positive leak-free performance

Compatibility

Designed as an OEM-style replacement for moisture and liquid indicator sight glasses used in refrigerant liquid line applications on residential and commercial refrigeration and air conditioning systems.

Installation Notes

Installation should be performed by a licensed HVAC-R technician in compliance with applicable refrigerant handling regulations, including EPA Section 608 requirements. Recover system refrigerant and relieve line pressure before removing or installing any sight glass fitting. Install with attention to flow direction if directional markings are present on the body. After installation, leak-check all connections and recharge the system before evaluating the moisture indicator color.
