Nylon Polypenco. pressure tubing is a super tough, low friction, high flexibility tubing that can be used for cable protectors or in short pieces, as small bushings and washers.

Suitable for use in oil, air, vacuum, fuel and low pressure hydraulic lines. It resists abrasion and wears better than aluminum or steel tubing. Has an extremely smooth inner surface with a very low coefficient of friction. Used for brake lines, and also as a conduit for the rudder cables in the Rutan VariEze and Long-EZ. Rated 1000 psi. Sold by the foot.

Use Poly-Flo fittings with standard wall tubing. Click here for the Poly-Flo fittings webpage.

Note: Poly Flo fittings cannot be used with High Burst Pressure tubing.
Must use SAE fittings (See Accessories Tab).

Nylaflow, nylaseal, nylon ns, nsr, etc... Did I buy the right one? Hope so. I went overkill with the high pressure stuff so install was a little tough as it is not very flexible. I used in my Rans brake lines. Time will tell!

The product itself is good. However, I was looking for something that is softer with a SHORE A value 60 or below. If you have tubings with that shore value, please let me know. Also, it would be nice to list the shore A value. - Tim

For my purpose I gave it 0 stars. Description indicated very flexible. My use was for a fuel site glass which required a truly flexible product which this wasnt. Being very cloudy would also have been a problem as a site glass.
