Cap Slip 10" (C647-100)

The 10" PVC Class 125 Slip Cap (C647-100) provides a clean, permanent solvent-welded end closure for 10" PVC piping systems — sealing the open end of a large-diameter pipe run completely and reliably without mechanical fasteners, gaskets, or threading. The slip connection accepts standard 10" PVC pipe directly into the socket for a solvent-welded joint, producing a flush, pressure-rated termination that integrates cleanly into the surrounding pipe assembly.

At 10" diameter, this is a large-format fitting serving the upper end of the PVC pipe size range — where Class 125 is a common specification for large-diameter applications in municipal water distribution, gravity-fed drainage, and high-volume commercial systems where the operating pressure requirements align with the Class 125 rating. The slip cap is the straightforward termination choice for line ends that are designed as permanent closures: dead-end headers, seasonal system shutoffs where the cap is installed as part of the design rather than a temporary measure, and system terminations where a flanged blind flange or threaded cap is not specified or practical at this diameter.

The solvent-welded slip connection produces a permanent, leak-resistant closure that becomes part of the pipe assembly itself — suited to below-grade installations, embedded or encased terminations, and any application where the line end is not expected to be reopened. For line ends that may need future access or extension, a flanged blind flange provides a bolted, removable alternative; the slip cap is the correct choice where permanence and simplicity are the design priorities.

Manufactured from rigid PVC to Class 125 specifications and NSF 61 certified for potable water contact, the C647-100 is appropriate for municipal water distribution, large commercial plumbing, irrigation, and industrial drainage applications operating within the Class 125 pressure envelope at 10" diameter.
