About Rod Ends

Yield Strength: Not Rated
Hardness: Not Rated
Specifications Met: ASTM B418 Type 1, MIL-A-18001

Cut and thread discs and other parts that draw corrosion away from nearby metal in water tanks, heat exchangers, and marine applications. These rods are made almost purely of zinc and meet MIL-A-18001, which means they break down faster than other types of metal. Attach your parts directly to the materials you want to protect.

Internally Threaded Ball Joint Linkages

With Seal

Able to stand up to frequent use, these linkages offer excellent wear resistance. They consist of ball joint rod ends with a ball stud attached to simplify mounting. The stud is machined to fit perfectly inside its housing and swivel in all directions—good for clutches, throttles, and shift control rods. Periodic lubrication may be required to keep them operating smoothly.

Linkages with seal have a seal to keep lubricant in and dirt out.

Internally Threaded Inline Ball Joint Linkages

Use these linkages to create inline pivoting connections. The ball-and-socket design allows the ball stud to swivel. All have a liner (also known as a boot) that not only keeps out contaminants, but also acts as a cushion to reduce vibration.

Corrosion-Inhibiting Rods and Pads

Also known as sacrificial anodes, these rods and pads protect tanks, water heaters, and heat exchangers from rusting by attracting corrosion that would otherwise damage equipment.

Rods have a threaded pipe connection.

Zinc rods protect against corrosion and scaling in salt water and fresh water.

Eyelet End Fittings for Gas Springs

Zinc

Thread these eyelet end fittings onto gas springs. They require an eyelet mounting bracket (sold separately) or a pin (not included) to mount the gas spring.

Select end fittings with a thread size that matches the rod and end thread sizes of your gas spring. The fittings will increase your gas spring's extended and compressed lengths, so add the Length 1 value for each fitting you attach.
