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.
Architectural 6063 Aluminum Round Tubes
- Yield Strength: 16,000 psi
- Hardness: Brinell 55 (Soft)
- Temper: T5
- Fabrication: Extruded
- Specifications Met: ASTM B221
More corrosion resistant and easier to form than multipurpose 6061 aluminum, 6063 is primarily used for exterior railings, decorative trim, and door frames.
Certificates with a traceable lot number are available for these products. Download certificates from ORDER HISTORY after your order ships.
Anodized Architectural 6063 Aluminum Round Tubes
- Yield Strength: 16,000 psi
- Hardness: Brinell 55 (Soft)
- Temper: T5
- Fabrication: Extruded
- Specifications Met: ASTM B221
The outside of these tubes is anodized to improve wear and corrosion resistance. Often called decorative anodize, the coating provides a uniform finish that readily accepts paint and adhesive. More corrosion resistant and easier to form than multipurpose 6061 aluminum, 6063 is primarily used for exterior railings, decorative trim, and door frames.

Hollow Linear Motion Shafts
Lighter than solid shafts, hollow shafts reduce your total system weight and allow you to run various media such as electrical wiring, compressed air tubing, coolants, or lubricants through the center. These shafts are smooth, hard, and wear resistant, so they work with linear bearings to reduce friction in manual and automated systems, such as those found in packing, machine tool, and material handling operations. The exterior of these shafts is turned, ground, and polished to tight diameter and straightness tolerances. The interior is unfinished.
These shafts are hardened on the surface, so they stand up to repeated motion. All have chamfered ends to remove sharp edges and reduce damage to bearings, housings, and other components during installation.
Alloy steel shafts are stronger and more wear resistant than carbon steel shafts.
Surface smoothness—The lower the microinch value, the smoother the finish and the less friction and wear it will cause on the bearing.
