Traveling Sprinkler Arms & Tee Replacement Kit for Orbit 58322 & Nelson 818653-4002 Tractor Sprinkler, T Part with Anti Leak Gasket for Efficient Watering Garden Lawn Watering (1 Pack)

What It Is

This replacement kit includes a new sprinkler arm assembly and tee fitting (T Part) with an anti-leak gasket, designed specifically for the Orbit 58322 and Nelson 818653-4002 traveling tractor sprinklers. It restores the rotating spray function and seals the connection to prevent water waste.

Fitment & Compatibility

Before buying, verify your sprinkler model number (on the frame or manual). This kit fits only Orbit 58322 and Nelson 818653-4002 traveling sprinklers—not other Orbit/Nelson models or generic tractor sprinklers. The tee threads are standard ½-inch female NPT, matching the sprinkler’s chassis hose fitting. Measure the existing arm’s length (approx. 6 inches) and pivot pin diameter (¼ inch) to confirm match. If your sprinkler uses a different arm design (e.g., 2-arm or fixed spray), this kit won’t work.

Key Things to Know

• Anti-leak gasket included – The gasket prevents water seepage at the tee joint, but ensure the sealing surface is clean and free of old debris for a proper seal.
• Installation is straightforward – No special tools needed; hand-tighten the tee onto the sprinkler’s hose fitting, then snap the arm onto the tee’s pivot pin. Takes about 5 minutes.
• Plastic construction – The arm and tee are molded plastic. They’re durable for normal use, but avoid overtightening the tee (can crack the threads) or dropping the sprinkler on hard surfaces.
• Check for wear on the pivot pin – If the original pin is bent or worn, the new arm may wobble. Replace the pin if needed (sold separately).

Should You Buy It

If your Orbit 58322 or Nelson 818653-4002 has a broken sprinkler arm or a leaky tee connection, this $13.99 kit is a cheap, reliable fix that restores full watering function. Avoid it if your model differs—measurements and thread type must match exactly. For a quick, no-hassle repair, it’s a solid buy.
