Female Adapter, Slip x FPT PVC Schedule 80 1-1/4" (835-012)

The 835-012 is a Schedule 80 PVC female adapter with a 1-1/4-inch slip (socket) inlet and a 1-1/4-inch female pipe thread (FPT) outlet. The socket end solvent cements directly onto standard 1-1/4" Schedule 40 or Schedule 80 PVC pipe, while the FPT port receives a 1-1/4" male-threaded fitting, valve, pump connection, or instrument tap. This adapter is the standard solution for transitioning a cemented PVC pipeline to a threaded interface — whether at a terminal equipment connection, an isolation valve, a union tail, or a service access point where a threaded joint allows future disassembly.

Manufactured from heavy-wall Schedule 80 PVC, the 835-012 provides greater wall thickness and mechanical strength than Schedule 40 equivalents, making it the appropriate choice for industrial, chemical, and high-pressure service environments where a solvent-cemented run must terminate at a robust threaded connection. The dark gray color is the Schedule 80 standard and allows quick visual identification in mixed-schedule installations. Apply a medium-bodied PVC primer and standard-bodied PVC cement per ASTM D2564 to the socket end; apply PTFE thread tape or an approved pipe thread sealant to any male-threaded fitting before engaging the FPT port. Do not overtighten threaded connections, as PVC threads can crack under excessive torque.

Industries & Applications:

• Industrial Process Piping — Terminates a 1-1/4" cemented Schedule 80 PVC process line at a female threaded port for connection to valves, instrumentation, chemical injection points, or threaded equipment inlets in corrosion-resistant systems.
• Chemical Processing & Water Treatment — Used at pump inlets, filter housing ports, and chemical metering connections where a cemented PVC run must transition to a threaded interface for equipment compatibility or future serviceability.
• Municipal & Commercial Plumbing — Provides a solvent-to-threaded transition at service valves, meter connections, and equipment tie-ins in 1-1/4" Schedule 80 commercial plumbing systems where added wall strength is specified.
• Irrigation & Agricultural Systems — Installed at pump discharge connections, pressure regulator inlets, and control valve bodies where a cemented 1-1/4" Schedule 80 mainline terminates at a threaded equipment port.
• Pool & Spa Equipment Rooms — Transitions cemented Schedule 80 chemical feed or circulation piping to threaded connections at chlorinator inlets, chemical pump ports, and auxiliary equipment manifolds.
• Laboratory & Semiconductor Facilities — Connects solvent-cemented Schedule 80 PVC distribution lines to threaded instrumentation, reagent dispensing equipment, or acid waste system components requiring a robust, chemical-resistant threaded interface.
