Orbit 38091 PVC Riser 1/2x12

It’s a common irrigation type plastic pipe riser. Just in case you wonder, the inside diameter (ID) is 0.75 inches (3/4 inch), the outside diameter (OD) is about1.04 inches and the total length (end-to-end) is 8 inches. The treaded part (male pipe thread “MPT”) of each end of the pipe is 3/4 inch long, the smooth section of the pipe is 6 1/2 inches (8 minus 1.5). It has “schedule 80” thickness, which means it has greater rigidity and pressure rating. It’s thicker than Schedule 40 pipe. Use plumber’s white teflon tape (PTFE) when assembling for best results, no leaks. It’s easy to assemble by hand.

I bought this along with some double female connectors to create a 36 inch riser for a sprinkler that needed to be taller due to bushes growing. I bought three, twelve inch pipes plus a pack of the connectors to make this happen. I probably could have gone to the orange box store and got a single piece and one connector but this was fairly easy and I believe a better price or similar. The only difference is that I spliced three instead of getting one piece and technically there is a greater chance of a leak I suppose. With some teflon tape there is no leaks and it worked for my application. I am using this same review for the connectors as well and I can't remember which set came with teflon tape. Plastic appears of high quality. The connectors came with a bunch in the pack so I am good for future projects.

Used in flower bed to get over the taller garden flowers. Works great. Very Happy.

Stronger than the cut-off ones

FOR WHATEVER REASON 3/4 INCH RISERS ARE DIFFICULT TO FIND. THE 1/2 INCH RISERS ARE ABUNDANT, BUT IF YOU WANT TO RAISE A ROTARY LAWN IRRIGATION HEAD ---- YOU NEED THIS 3/4 INCH SIZE. GOOD PRICE AND READILY AVAILABLE ON AMAZON. WOULD RECOMMEND . . . . .

My irrigation system has been in the ground for a while. Living in the dirt, it is subjected to many environmental pressures such as shifting soil due to winter weather, rain and drought pressures. These risers allow for some adjustments in the main irrigation line to the spray head to maintain mowing clearance and sprayer height for water coverage. Plus, the soil conditions are "corrosive" to older previously used risers. These sturdy units and others of varying lengths bring back the spray head location to life with great water coverage. Always have a few spares to re-engineer any spray head location.

durable which is good, much easier to control flow of the manifold now

Nice thick plastic pipe, should last decades.

I only got 3 out of 5. Were the other two on back order?

This item was as expected. Delivery to my home was a good bonus.

Used for repair job and additional sprinkler head on sprinkler system

Got what I expected

Five times more expensive than Home Hardware!
