Customer Questions & Answers

What part does the impact sprinkler screw into?

I have hand lines for irrigating hay fields. The pipes have 3/4" risers and existing 3/4" rain bird impact sprinklers. I am replacing these 3/4" sprinklers with 1/2" Orbit brass impact sprinklers and need to have the fitting to adapt from 3/4" pipe thread to the thread on the 1/2" new sprinkler heads. I need 14 of these items...
Asked by: Andy
Andy, for this you will need a 3/4" female x 1/2" female brass adapter. It is important that, should you purchase a metal adapter for the connection, that you choose brass - if it is a different metal, there's some risk of the metals reacting to each other. Please feel free to contact us for more product details or further explanation. You can reach our Support team at 1-800-488-6156. Thanks!

We have a orbits model 58308D and I need a new head... will this model work for me?

My tripod sprinkler is 10 months old used about 3 months and the head will not rotate it just sprays straight out... What should I do.

Customer Reviews

1/2 in. Brass Impact Head is rated 4.0 out of 5 by 2.
Rated 5 out of 5 by from The Best out of Box ! I own three of these heads. They are made of brass, Top quality. They spray in different degrees and a true full circle unlike Rainbird. Tried Rainbird and brought back to store. This unit trip arm flips up and does a TRUE 360 degree circle. Orbit is the best in my eyes, Spray pattern is also slower and better. Orbit stands behind product for six years, no questions asked. Thanks ORBIT.

Rated 3 out of 5 by from This product always fails This sprinkler works very well-for one season. Then you can't get them to work but one direction. If you lift up on the sprinkler, it turns freely. When you put water pressure on it, it drags. I've been using this type off and on for about six years. The end result is always the same for all of them I have purchased from Home Depot. But what do you buy? All the sprinklers are Chinese junk.
