Product Description

The Nu-Calgon 4182-24 Cal-Blue Plus Micro Gas Leak Detector has outstanding freeze-protection down to 5°F (and up to 225°F). Cal-Blue products are the complete gas leak detector. Not only do they detect the smallest leak, they also provide other significant benefits. The high viscosity formula provides long lasting bubbles, and enables the product to remain in contact with the applied surface for an extended period of time, thereby allowing the smallest of leaks to be detected. It is also non-corrosive to metal, and this is a significant feature as it helps to maintain the integrity of piping, tubing and fittings. THE NU-CALGON 4182-24 CAL-BLUE PLUS MICRO GAS LEAK DETECTOR IS FOR PROFESSIONAL USE AND SHOULD ONLY BE USED IN ACCORDANCE WITH ALL REGULATIONS AND PROPER SERVICE PRACTICES. PLEASE SEE PRODUCT LABEL OR CONTACT NU-CALGON DIRECTLY FOR USE INSTRUCTION. IT IS RECOMMENDED TO UTILIZE THE APPROPRIETE PPE (PERSONAL PROTECTIVE EQUIPMENT) DURING APPLICATION.

WARNING:

CHOKING HAZARD -- Small parts. Not for children under 3 yrs.

Customers appreciate the sturdiness of the gas smoke fire alarm. It stays in place and clings to surfaces long enough to detect gaseous bubbles. They find it thick, viscous, and the right consistency.

7 customers mention "Spray effectiveness"4 positive3 negative

Customers have mixed opinions about the spray's effectiveness. Some say it doesn't spray, is easy to squirt on pipe fittings and valves, while others say it won't detect a leak and the spray nozzle is a straight stream that can't mist the spray.

"This product identifies leaks well, but is very thick, so you use a lot more than other brands." Read more

    As others have said about the spray nozzle being a straight stream and cant mist the spray in a broad area but besides that it works great .I Found my leak in just a few minutes and didn't use much soap, did waste a small amount getting it where it was needed. I would recommend this soap and maybe change out the sprayer with an adjustable one.

    This is a great leak detector for car AC, Home AC, car tires and anything that requires leak detection. If you spray it on the schrader valve be sure to rinse it and then let the schrader valve dry before putting the cap back on it. Every homeowner should check their systems for leaks when the AC systems are restarted each year. This could save you thousands in repair costs if you have a small refrigerant leak.

    Exactly what I needed. Found a leak at a fitting that was escaping my best efforts of discovering it. Easy to squirt on the pipe fittings and valves. Thick so it stays easy to spread around with a small brush in tight places where it is hard to squirt. I covered all the joints in the suspect line with this as soon as I got it and about five minutes later I saw the tiny bubble slowly forming. I was only loosing about a quarter psi over 24 hours and this found it. I took that joint apart, cleaned it up, applied fresh pipe dope, reassembled and my pressure test held rock solid at 15 psi for more than 24 hours with no loss.
