Overview

Nylo-Seal tube fittings are exceptionally strong. The bodies, made of nylon, are stronger than machined fittings of similar composition. They are furnished complete with nut/sleeve assemblies, made of acetal copolymer. Since the sleeve snaps into and is retained by the nut there is no fumbling for a loose sleeve. Just insert tube into the fitting and tighten the nut 2 to 2-1/2 full turns. Note: The most frequently used combination of tube and pipe sizes are 1/4" Tube x 1/8" Pipe and 3/8" Tube x1/4" Pipe.

For Nylo-Seal tubing, see "Accessories" tab

Q&A

Q: Do you have to use Nylo seal fitting 259-N insert, put into your tube before you screw on the nut that comes with this fitting on to the fitting ?Or you just slide the nut over the tubing with no insert and then screw it onto the fitting?

The insert will already be inside the nut. You will just slip your tubing inside the fitting and tighten it down. Nothing else needed.
