PVC Coupling, SxS 1

Joining two lengths of 1" PVC pipe is one of the most basic moves in any plumbing run, and this American Granby slip x slip coupling makes it permanent and leak-free. Both ends are slip sockets that solvent-weld directly to Schedule 40 pipe, chemically fusing the joint into a single continuous run that is as strong as the pipe itself.

The workhorse of straight-line PVC

Slip couplings are the foundation of straight-line PVC plumbing. Use them to extend a run, splice in a repair section, or connect pipe to other slip-end fittings in a softener or filtration manifold. Because the solvent-weld bond chemically welds the pipe and fitting together rather than relying on threads or compression, a properly made joint will not loosen, back off, or weep over time the way a mechanical connection sometimes can. That makes the slip coupling the default choice anywhere you want a permanent, maintenance-free connection.

• Connection: 1" slip socket x slip socket
• Fitting type: coupling
• Material: Schedule 40 PVC
• Permanently joins two 1" pipe sections
• Solvent-weld for a sealed, pressure-rated joint
• Light at about 0.07 lb each

For best results, cut the pipe square, deburr the edges, and wipe both surfaces clean before applying PVC primer followed by cement to both the pipe and the socket. Push the pipe fully home with a slight twist to spread the cement evenly, then hold the joint briefly while the bond sets. The corrosion resistance and smooth bore of PVC keep treated water flowing cleanly with no rust contributed by the fitting and no internal scaling to restrict the line. Dependable and economical, this American Granby coupling is a staple for residential and light-commercial water-treatment plumbing.

Because PVC will not corrode internally, the inside diameter stays clean and full-bore for the life of the line, preserving the flow and pressure that metal pipe loses to scale and rust over the years. That matters in water-treatment plumbing, where consistent flow keeps softeners and filters operating within their design range. Pair this fitting with quality pipe, proper primer and cement, and clean, square cuts, and it will deliver dependable, leak-free service for the long term.
