RV PEX Water Line Plumbing Fittings

Flair-It® Fittings – Sold at California RV Specialists

California RV Specialists proudly sells RV PEX water line plumbing fittings by Flair-It, one of the most trusted and proven plumbing fitting systems used in RVs across North America for more than 30 years.

Flair-It fittings are widely recognized as the original push-on compression fitting, offering a simple, reliable, and leak-free solution for RV fresh water plumbing repairs and upgrades.


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.

  • Simplicity

  • Long-term integrity

Simply put — it just works.
