Wear-Resistant Nylon Hexagonal Bars
- Color: Off-White
- Max. Temperature: 185° F
- Tensile Strength: 11,200-12,300 psi (Good)
- Impact Strength: 0.6-1.4 ft.-lbs./in. (Poor)
- Hardness: Rockwell R108-R121 (Hard)
- For Use Outdoors: No
- Specifications Met: ASTM D5989, ASTM D6779, UL 94 V-2
These nylon 6/6 hex bars are often machined into gears and other high-wear parts. They have a slippery surface that reduces wear caused by friction.

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. Black zinc–plated brass pipe has a shiny finish that offers better corrosion resistance than nickel-plated brass and stands up to salt-spray applications. Chrome-plated brass pipe has a mirror-like finish and provides better corrosion resistance than nickel- and black zinc–plated brass.
Fully threaded pipe is also known as a close nipple; it is threaded on each end to the center.
NPTF (Dryseal) threads are compatible with NPT threads.
Universal threads have a Buna-N rubber gasket to protect against leaks.
