Key details

• 1-1/2" size
• Solvent-weld (cemented) connection, not threaded
• Permanent, leak-tight joint when cemented correctly
• Use the correct primer and solvent cement for the pipe material

Where it fits

Nelsen Hub, 1-1/2" Solvent. Manufacturer: Nelsen Corp. Part #: D1074.

Nelsen 1-1/2" Solvent Hub

This Nelsen hub is a plumbing fitting with a 1-1/2 inch solvent-weld socket, used to make a clean, permanent connection in PVC piping around a water treatment system. Solvent-weld hubs accept a matching pipe that is glued into the socket with PVC cement, chemically fusing the two into a single leak-resistant joint. It is a simple but essential piece for tying valves, tanks, bypasses, and distribution plumbing into your larger system.

Where It Is Used

Hubs like this show up wherever larger-diameter treated or raw water lines need to be joined or transitioned, such as on commercial-scale filters, backwash and drain runs, or manifold plumbing feeding multiple tanks. Because it is a solvent-weld design, it is chosen for connections meant to stay put rather than be unthreaded and reassembled frequently.

Installation Notes

A quality solvent joint depends on clean, dry, deburred pipe, the right primer and cement, and a firm quarter-turn seating of the pipe into the hub while the cement is wet. Give the joint proper cure time before pressurizing. Because sizing and fit have to be exact for a solvent connection to seal, it pays to confirm the pipe diameter and schedule you are working with. It is always wise to dry-fit the assembly and confirm your layout before the cement goes on, because a solvent joint cannot be taken apart once it cures. Water Softener Plus includes fitment guidance with your order and is happy to help you verify that this 1-1/2 inch hub matches your plumbing before you commit to gluing it in place, so your connection ends up clean, square, and leak-free.
