If you want to get the most out of your Viair air compressor, you need this check valve. It’s specially designed to work with Viair products and keep air flowing in one direction only. That means no more air leaks, faster tank filling, and longer compressor life.
This check valve is easy to install. It has ¼″ Male NPT on one side and ¼″ Female NPT on the other. Just thread it into any NPT ported fitting or tank and you’re good to go. Don’t forget to use some thread sealant or Teflon tape for a tight seal.
What’s a check valve? It’s a simple device that lets air pass through it only one way. It prevents tank pressure from going back into your compressor and messing things up. Trust us, you don’t want that.
This product can expose you to chemicals including lead, which is known to the State of California to cause cancer and birth defects or other reproductive harm. For more information, go to www.p65warnings.ca.gov.
