OLAB Masterflow is a moisture or liquid indicator designed for high-pressure professional CO2 (R744) refrigeration systems. The body is manufactured from brass EN12164 – CW614N (OT58), while the spin-locked closing ring is AISI 303 stainless steel, a material pairing chosen for dimensional stability, corrosion resistance and long-term reliability in demanding environments.

A crystal inspection window gives operators an immediate visual check of refrigerant condition or circuit moisture level. Sealing is provided by a dual O-ring system in 100% PFAS-FREE, OLAB-certified EPDM on the body, supplemented by an additional EPDM O-ring on the closing ring.
Masterflow installs easily thanks to a selection of compatible adapters: male NPT-thread adapters, stainless-steel weld-on adapters for stainless-steel pipes and ISO 228 cylindrical male gas adapters equipped with the same OLAB-certified EPDM O-ring.

This range of options simplifies integration into systems with differing geometries and connection standards.
Rated for pressures up to 120 bar (1 740 psi) and temperatures from –50 °C to +150 °C (–58 °F to +302 °F), Masterflow complies with UL 207 and offers a safe, versatile solution for visual monitoring of refrigerants in modern natural-refrigeration plants.
