Specifications & product details

Overview

Nu Calgon Cal-Blue® Plus Gas Leak Detector – 7 oz Pressurized Spray (MFG# 4182-35)

Cal-Blue Plus is a professional-grade gas leak detector spray designed for precise detection of even the smallest micro-leaks. Its high-viscosity formula produces long-lasting bubbles that stay in contact with surfaces longer, improving leak visibility on pipes, tubing, fittings, and coils.

This advanced spray is powered purely by air, containing no gas or chemical propellants, and can spray from any angle. The formula is non-toxic, non-corrosive, and safe for use on metal surfaces, with freeze protection down to 5°F.
