PVC Pipe Nipples Schedule 80 are a specific type of Schedule 80 pipe fitting. In sprinkler systems they are used in cases when regular sized pop up sprinklers do not pop high enough out of the ground. The PVC pipe nipple Schedule 80 will act as an extension to all other fittings, attachable either via threads or male-female and slip-spigot tips.

(It is important to note here that when dealing with irrigation equipment or landscape supply the measurements are denoted as inches in diameter by inches in length. Thus, when referring to a PVC pipe nipple Schedule 80 that is 1/2 inch by 3 inch, the 1/2 inch measurement denotes the diameter, while the 3 inch measurement refers to the length of the nipple.)

The PVC pipe nipples schedule 80 are offered in a wide range of sizes. Beginning with 1/2 inch in diameter, PVC pipe nipple schedule 80 can be up to 6 inches in diameter. PVC pipe nipples schedule 80 also range in length from "close" – the shortest possible length, to as long as 48 inches. As with most PVC supplies, PVC pipe nipples Schedule 80 can be used in any forum, not just the landscape supply or irrigation supply industry.
