Plastic Pipe Nipples

Why choose our 'machined' nipples?

Because Excalibur extrudes them from our own stock, so you can pick from the widest variety of high quality plastic pipe found anywhere.

Plastic pipe nipples are a critical, often overlooked, component of fittings in any irrigation system. Excalibur produces only machined nipples. Landscape architects, landscape engineers, and municipal agencies regularly specify machined plastic pipe nipples.

Each component in an irrigation system is like a link in a chain; any weak link cripples the entire system. A common, and often costly, mistake is to assume that there is savings to be found in buying the least expensive nipple. In reality, one is gambling a savings of a few pennies against the odds of expensive repairs. But you can avoid costly tear out and a labor intensive re-inspection. Excalibur nipples now come sealed with safety tape identifying them as "machined nipples" for your assurance.

More Excalibur advantages:

· We maintain an extensive inventory at all times - most orders can ship the same day.
· We use our own extruded pipe, so custom lengths and threading can be done quickly.
· One stop shopping for Threaded Pipe.
· Our stock pipe nipples with precision-machined threads tend to seal better than molded nipples with mold lines, and can be cut anywhere for an effective solvent weld joint.
