Why Flair-It® Fittings Are Trusted in RV Plumbing

Flair-It compression fittings are designed to work with:

  • PEX water line
  • Polybutylene (PB) (the older gray pipe found in many RVs)
  • Polyvinyl tubing

Installation is straightforward—the tubing is pushed onto and over a cone-shaped barb, creating a seal on the inside diameter of the pipe. This design eliminates many common leak points found in traditional fittings.

What Makes Flair-It® Different

  • Inside-diameter sealing design
  • No crimp rings required
  • No special tools needed
  • Proven leak-free performance
  • Approved for residential and recreational use

With millions of fittings in service today, Flair-It continues to be trusted by RV technicians, homeowners, and hardware retailers alike.
