Flair-It Sales: Pressurized Water System Tubing & Fittings
When it comes to reliable, leak-free connections in pressurized water systems, Flair-It Sales has built a reputation that spans more than three decades. Their pressurized water system tubing and fittings are engineered around a patented compression design that fundamentally changes how plumbers, RV owners, and marine enthusiasts approach water system repairs and installations.
The Patented Flair-It Compression System
At the heart of every Flair-It fitting is a patented flared-cone and nut design. The fitting's insert pushes into the interior of the tubing while a nut seats on the exterior — tightening the two components together creates a dual-surface seal that grips both the inside and outside diameter of the pipe. This approach produces a bond capable of withstanding up to 90 pounds of pressure without the need for solder, cement, crimp rings, or Teflon tape.
Flair-It fittings are constructed from durable Polyoxymethylene (POM), a high-strength engineering plastic that resists corrosion and scaling — a critical advantage in pressurized fresh water environments where metal fittings can deteriorate over time. Because the fittings do not rely on metal crimp rings, there is no risk of cracking the tubing during installation.
Tool-Free Installation for PEX, PB, and Polyvinyl Tubing
One of the most practical advantages of Flair-It's pressurized water system fittings is their compatibility across multiple tubing types. They work with PEX (A, B, and C), PERT tubing, Polybutylene (the legacy grey pipe found in many older RVs), and Polyvinyl tubing — making them an ideal solution for repairs where the existing plumbing type is already in place. Available in 3/8", 1/2", and 3/4" sizes, the lineup spans couplings, elbows, tees, adapters, caps, stop valves, and supply valves to handle virtually every connection scenario in a pressurized water circuit.
Installation is straightforward: push the tubing onto the cone-shaped barb of the fitting and tighten the nut — no special tooling required. This makes Flair-It fittings especially valuable in tight spaces common to RV bays, boat engine rooms, or under-sink cabinetry where maneuvering a crimp tool is impractical.
Certified and Trusted Across Applications
Flair-It fittings are NSF-listed to Standard 14 and comply with ASTM D3309, confirming their suitability for hot and cold potable water service. This certification underpins their use across a wide range of environments — from recreational vehicles and marine vessels to residential homes and even medical facilities. The fittings are also reusable, allowing them to be disconnected and reconfigured without damage to the tubing or the fitting itself.
With over 250 variations in the broader Flair-It catalog and millions of fittings in active use across North America, this brand has become a go-to choice for anyone maintaining or building out a pressurized freshwater system. Whether you're tackling a fresh water pump line on a boat or rerouting a supply line in an RV, Flair-It Sales delivers the reliability and ease-of-use that demanding, space-constrained installations require.
