Questions about this product
- What does this check valve do in an air system?
- It lets air flow one way and blocks it from going back. The spring inside seals fast to stop backflow, which holds your downstream pressure steady. It also protects sensitive parts and keeps tank pressure from bleeding off when tools disconnect.
- Which hose size should I order?
- It comes in 6, 8, 10, and 12mm hose sizes, matched to models CV-01 through CV-04. CV-01 is 6mm and CV-04 is 12mm. Pick the size that matches your air tubing's outside diameter for a proper push-to-connect fit.
- How do I install it in my air line?
- The compact inline body drops straight into an existing air line. The 1/8" NPT thread screws into standard fittings, tools, or compressors, so use sealant there. Push your hose into the quick-connect end, and mind the arrow so flow points the right way.
