Coupling, Slip 10" (C629-100)

The 10" PVC Class 125 Coupling (Part No. C629-100) is a large-diameter, white-body fitting designed to join two sections of 10" PVC pipe in a continuous, same-size solvent-cemented run. Both ends accept solvent-cement joints in a slip (socket) configuration, producing a rigid, leak-resistant connection that becomes structurally integral to the pipeline once cured. As one of the most fundamental fittings in any large-diameter PVC system, the coupling is the essential component for extending pipe runs, completing field cuts, repairing damaged sections, and joining pipe lengths wherever a straight, same-size connection is required.

At 10", this coupling serves the large end of the PVC fitting lineup where the fitting itself represents a meaningful procurement item. Large-diameter couplings are specified across municipal water transmission and distribution infrastructure, major agricultural and landscape irrigation mains, industrial process water systems, and stormwater conveyance applications — environments where 10" PVC is chosen for its corrosion resistance, hydraulic efficiency, long service life, and cost advantage over metallic pipe in non-aggressive fluid service.

The coupling's role in repair and maintenance scenarios is worth noting at this size. When a section of 10" main is damaged, cut, or modified in the field, couplings are required at both ends of the replacement pipe section to re-establish the continuous run. Having the correct coupling in stock — correct size, correct pressure class, correct color — is a prerequisite for completing the repair without waiting on special-order fittings, making this a routine stocking item for municipalities, irrigation contractors, and industrial maintenance operations working with 10" PVC infrastructure.

As a Class 125 fitting, this product is part of the C-prefix series in Charlotte Pipe's large-diameter PVC lineup. The Class 125 pressure designation is specific to large-diameter PVC fittings and should be verified against the manufacturer's current catalog to confirm pressure class, dimensional standard, and applicable use conditions before specifying for pressure-rated applications.

Manufactured from Type I, Grade I PVC compound and conforming to ASTM D2466 dimensional standards, this fitting is compatible with Schedule 40 or Class 125 PVC pipe and solvent cements meeting ASTM D2564.
