Use these sleeves with brass compression nuts and fittings to create a seal on plastic and rubber tubing.

Tube supports slip inside tubing to prevent the walls from collapsing.

Safe for use in your air brake line, these fittings meet Department of Transportation FMVSS 571 standards. They’ve been tested for thermal cycling, vibration, and burst pressure, so put them to work right away.

These fittings include a nut with a built-in sleeve (ferrule), so there’s no need to remove the nut for assembly.

Not only are these chrome-plated brass couplings corrosion resistant, they’re also durable enough to handle pressures up to 250 psi and can be used with vacuum.

Made of nickel-plated brass, these fittings have better corrosion resistance than unplated brass fittings.
