Charlotte Pipe Schedule 80 1-1/4 in. Slip X 1-1/4 in. D FPT PVC Pipe Adapter

Charlotte Pipe Schedule 80 1-1/4 in. Slip X 1-1/4 in. D FPT PVC Pipe Adapter is a purpose-built connector designed to simplify DWV installations by bridging glued PVC piping with threaded fittings in a single, dependable component. Built from durable Schedule 80 PVC, this adapter handles demanding underground and exterior environments while maintaining a clean, leak-free transition.

Designed for reliability in drainage, waste, and vent systems, this 1-1/4 in. slip x 1-1/4 in. D FPT adapter lets you glue a Schedule 80 PVC pipe on the slip end and thread onto a male 1-1/4 in. NPT connection on the FPT end. The result is a secure, versatile connection that reduces the need for multiple fittings and minimizes potential leak points in tight or buried installations.

• Dual-end design: Slip end fits 1-1/4 in. Schedule 80 PVC pipe; FPT end accepts 1-1/4 in. male-threaded connections for a robust threaded transition.
• Schedule 80 PVC construction: Thicker walls for added strength and resistance to impact, making it ideal for underground and high-use DWV applications.
• Lead-free and code-certified: IAPMO certified and NSF listed, helping you meet plumbing codes and safety requirements for residential and commercial projects.
• Underground-rated DWV compatibility: Built to perform in drainage, waste, and vent systems that run below ground or outdoors exposed to moisture.
• Temperature tolerance: Rated for up to 140°F, suitable for standard household fluids and typical hot-water drain scenarios within that range.
• Not ANSI certified: Clear specification that this adapter does not carry ANSI certification, but it aligns with common DWV and plumbing standards for its class.

Why this adapter stands out

What makes this Charlotte Pipe adapter different is its seamless combination of a glued-slip connection with a threaded FPT end, all in a single, corrosion-resistant PVC part. This level of integration reduces installation time, limits potential leak points, and offers a straightforward solution for transitioning between glued PVC runs and threaded piping in complex DWV configurations.

Ideal Use Scenarios

• Underground DWV projects where a smooth glue-in section meets a threaded connection for subsequent fittings or pipe segments.
• Repairs or retrofits in basements, crawl spaces, or outdoor drainage runs where space is tight and reliability is critical.
• Conversions from glued PVC to threaded components without swapping multiple fittings.
• Residential and light commercial drainage systems that require durable Schedule 80 performance.

Practical installation tips

• Clean and dry the slip end before applying PVC cement; ensure a proper glue joint for a secure 1-1/4 in. connection.
• Wrap the FPT end with an appropriate thread sealant or PTFE tape rated for PVC/NPT threads to prevent leaks at the threaded connection.
• Inspect for alignment as you assemble to avoid cross-threading or binding; tighten to the manufacturer’s recommended torque for a reliable seal.
