Product review (5 stars): Quality Humidifier Solenoid Valve!!
Fantastic valve!

Pressure tested, with no leaks. Product is top notch! 5/16" fitting is what we needed, so had no issued fitting it to our GeneralAire 990-53, using copper tubing.

Some details:
Universal Humidifier Solenoid Valve
Compare to Part # UHS24

This valve can either be used with plastic or copper tubing
This replacement solenoid valve replaces the most popular 24 VAC humidifier valves including: Aprilaire 4040, GeneralAire 990-53, Honeywell 32001639-002 & Skuttle A01-0814-148

I highly recommend this valve. It is high quality and will satisfy your replacement needs! I received this product for free or at a discounted rate in exchange for product testing and review. I am under no obligation to provide a positive review and received no incentives or rewards for doing so. My aim is to highlight features and drawbacks that I would want to know about as a buyer, not hype the product for the manufacturer to increase sales. My remarks are sincere and true. I work very hard trying to write insightful and thoughtful reviews for each item. My hope is that these reviews are helpful to others. Please let me know how I am doing by voting YES if you think that my review helped you
