High-Pressure Hard Plastic Tubing for Air and Water
Excellent strength and durability allow this tubing to handle high-pressure air and water applications.
Nylon tubing can handle higher pressures than polycarbonate tubing. It won’t crack even at low temperatures. Tubing is semi-flexible, so it is good for gradual bends. Semi-clear tubing gives you a limited view inside the line. Opaque tubing doesn’t allow you to see what’s flowing through the line.
- Semi-Flexible
- Compatible with Compression Fittings, Push to Connect Tube Fittings or both; see For Connection Style
- See table for hardness
- Temperature Range: See table

Smooth-Bore Seamless Stainless Steel Tubing
Seamless construction with no weld bead gives this tubing an interior with unrestricted flow. It is stronger than welded tubing and can be flared without splitting.
316 stainless steel offers excellent corrosion resistance.
Tubing that meets ASTM specifications adheres to international standards for dimensions and materials.

- Temperature Range:
304 Stainless Steel: -425° to 1500° F
316 Stainless Steel: -325° to 1500° F - Bending Method: Tube Bender
- For Use With: Natural Gas, Water, Oil, Air
- Compatible Tubing Fittings: Butt Weld, Compression, Flared, and Yor-Lok
Precision Stainless Steel Tubing
This tubing is made to tighter tolerances than other stainless steel tubing. It is welded with a smoothed weld bead on the inside to reduce particle buildup. Tubing connects by welding.
304 stainless steel has very good corrosion resistance.
316 stainless steel offers excellent corrosion resistance.
- Temperature Range: -420° to 600° F
- Bending Method: Tube Bender

High-Pressure Plated Brass Threaded Pipe Nipples and Pipe
The plating on this pipe creates a shiny finish and provides extra protection in corrosive environments. It has the strength to handle high-pressure applications.
Nickel-plated brass pipe provides better corrosion resistance than unplated brass.
Fully threaded pipe is also known as a close nipple; it is threaded on each end to the center.
Universal threads have a Buna-N rubber gasket to protect against leaks.
