Coupling, Slip x Slip PVC Schedule 80 6" (829-060)

The 6" PVC Schedule 80 Coupling (829-060) is a full-size, same-diameter coupling designed to join two sections of 6" Schedule 80 pipe in a permanent, pressure-rated solvent-welded assembly. Both ends use slip (socket) connections that accept standard 6" Schedule 80 pipe, producing a clean inline joint with no change in pipe diameter, flow path, or pressure rating across the connection.

At 6" diameter, this coupling operates at the large end of the Schedule 80 PVC size range — where the combination of high wall thickness, elevated pressure rating, and gray PVC chemical resistance positions it for the most demanding commercial and industrial applications. Whether used to extend a run of 6" Schedule 80 pipe, repair a damaged section, or complete a field measurement adjustment at final assembly, the 829-060 delivers a joint that matches the full structural and chemical performance of the surrounding pipe.

The coupling's value in large-diameter Schedule 80 systems goes beyond simple pipe joining. In chemical processing and industrial process piping, 6" Schedule 80 couplings serve as transition points between pipe runs from different sources, allow field-length adjustments during system assembly, and provide a clean inline connection at equipment or valve flanks where a threaded or flanged transition is not required. The solvent-welded slip connection keeps the joint profile minimal and the assembly straightforward — no threading, no gaskets, no bolting hardware required at the coupling point.

Manufactured to Schedule 80 specifications and dimensionally compliant with ASTM D2467, the 829-060 ensures reliable compatibility with Schedule 80 pipe and fittings from all major manufacturers. Gray PVC construction provides broad chemical compatibility with acids, alkalis, and a wide range of industrial process fluids. NSF 61 certification confirms suitability for potable water contact where required.

Specifications:

Industries & Applications:

• Chemical Processing — inline pipe joining, run extensions, and field-length adjustments in 6" chemical feed, process fluid distribution, and plant utility headers where Schedule 80 chemical resistance and pressure performance are specified
• Industrial Process Piping — coupling connections in large-diameter cooling water, recirculating process, and plant utility systems requiring the elevated wall thickness and pressure rating of Schedule 80 gray PVC
• Water & Wastewater Treatment — inline pipe joins and run extensions in treatment plant process piping where 6" Schedule 80 is specified for pressure or chemical compatibility
• Commercial & Industrial Plumbing — pipe joining and field adjustment connections in large-diameter high-pressure mechanical systems where Schedule 40 pressure ratings are insufficient for the application
• Aquaculture & Food Processing — corrosion-resistant inline pipe connections in large recirculating systems and chemical-exposure fluid handling installations
• Irrigation & Agriculture — inline joins and run extensions in 6" high-pressure chemical injection and large-scale primary distribution headers where Schedule 80 is specified
