B/U PLAIN END SLIP/SLIP 80MM BLACK

The Hayward B/U Plain End Slip/Slip 80 MM Black is a plumbing fitting used in pool and spa systems — basically a short-length coupling or sleeve that allows you to join two pieces of pipe (or two fittings) using “slip” (socket-glue or socket-fusion) connections on both ends. The “80 MM” refers to the diameter (roughly 3.15 inches), which matches corresponding pipe or fitting sizes. As a “plain end slip/slip”, it offers a smooth internal path — no threads, unions, or moving parts — making it ideal when you want a permanent, glued (or fused) connection that’s strong and leak-resistant. Because it’s made by a reputable pool-equipment manufacturer (Hayward), the material and build quality are intended for use with pools or spas: suitable for water flow, resistant to pool chemicals, and compatible with standard pool-grade PVC or polymer piping.

In practice, you’d use this piece when you’re constructing or repairing fixed plumbing runs — e.g. connecting pump, filter, or spa plumbing sections — where adjustability isn’t needed and a permanent, sealed joint is acceptable.
