Value Brand Nylon Tubing 5/16" OD 50 ft Natural

SKU CH-1FJX-90WRX

Nylon tubing with 5/16 inch outside diameter, 15/64 inch inside diameter, 50 foot length, 333 psi working pressure at 68 degrees F, and -4 to 175 degrees F temperature range

  • Natural nylon resists corrosion for clean fluid handling
  • 333 psi working pressure at 68 °F handles demanding pneumatic lines
  • 50 ft continuous coil reduces joints and leak points
  • Shore D 60 hardness keeps shape under vacuum to 28 in Hg
  • Temperature range –4 °F to 175 °F suits hot and cold environments

5/16" OD Nylon Tubing — 50 ft

This 50-foot coil of nylon tubing has a 5/16 inch outside diameter and a 15/64 inch inside diameter with a 3/64 inch wall thickness. It is suited for fluid or air lines in automotive, plumbing or workshop installations where a natural-colour, semi-rigid tube is specified. The Shore D 60 hardness gives enough stiffness to hold shape while remaining easy to route by hand.

Pressure and temperature limits

The tubing is rated for a maximum working pressure of 333 psi at 68 °F and a burst pressure of 660 psi. It withstands a vacuum rating of 28 in Hg and operates continuously from -4 °F to 175 °F. Dimensional tolerance is held to +0.002 / -0.004 inch, so fittings seat consistently across the full length.

Capacity and headroom

The 50-foot length provides ample run length for most bench or vehicle routing tasks without splices. The 333 psi working pressure covers typical shop air and low-pressure hydraulic circuits, while the 660 psi burst margin adds safety against pressure spikes. Systems that exceed 333 psi continuous pressure or require temperatures above 175 °F will need a different hose specification.

Questions about this item

How do I decide between the 5/16 in outside diameter and the 15/64 in inside diameter when ordering?

The 5/16 in outside diameter determines fitting compatibility, while the 15/64 in inside diameter sets the flow area. Choose based on which dimension your connectors or system require.

What does the 333 psi maximum pressure at 68 °F mean once the tubing is installed?

It is the highest continuous working pressure at that temperature. Pressure capacity drops as temperature rises toward the 175 °F limit, so derate accordingly for hotter fluids.

What vacuum level can this nylon tubing handle in practice?

It is rated for 28 in Hg vacuum, so it will hold full vacuum without collapsing at room temperature.
