1" & 1-1/4" Connector PVC Socket Kit

Need to plumb a treatment tank into a system that mixes pipe sizes? The Pentair 1" & 1-1/4" Connector PVC Socket Kit is built for exactly that situation. This kit provides the PVC socket connectors required to tie a control valve or tank port into either 1" or 1-1/4" pipe, giving installers the flexibility to match whatever line size the home or facility already has without sourcing separate adaptors for each scenario.

The socket connections are designed for solvent-weld PVC assembly, which produces the clean, permanent, leak-tight joints that are the standard for water-treatment plumbing. Before cementing, dry-fit each connector, deburr and chamfer the cut pipe end, and apply primer followed by the correct solvent cement so the joint fuses fully rather than merely sticking. Because the kit covers two of the most common pipe sizes, it spares you from chasing individual fittings across multiple suppliers and lets you keep a single versatile part on the shelf that handles the bulk of residential and light-commercial connection jobs. The 1-1/4" option is especially valuable on higher-flow filters and softeners, where the larger bore preserves service flow and minimizes the pressure drop that a narrow connection would otherwise introduce across the inlet and outlet.

Kit highlights

• Connects to both 1" and 1-1/4" PVC pipe
• Solvent-weld socket joints for durable, sealed connections
• Tank-fitting component for softener and filter systems
• Larger size option reduces flow restriction
• Approximately 0.50 lb per kit
• Genuine Pentair tank-connection hardware

This connector kit is the kind of part that makes an installation go smoothly instead of stalling at the plumbing stage. When you're setting a new mineral tank, swapping out a control valve, or reconfiguring an inlet and outlet manifold, having the correct PVC socket connectors on hand means you can finish the run without a second trip to the supply house. Let freshly cemented joints cure fully before pressurizing, then check for weeps at startup. Properly sized, solvent-welded connections are what keep a treatment system tight under working pressure for years rather than developing the slow seeps and stress cracks that plague mismatched or oversized fittings. For installers building Pentair-equipped tank systems, this dual-size socket kit is a practical, reliable choice that adapts cleanly to the existing pipework and keeps the project moving.
