Cap, Slip PVC Schedule 80 1/2" (847-005)

This 1/2" Schedule 80 PVC Slip Cap provides a permanent, solvent-cement closure for any standard 1/2" PVC pipe end in industrial, chemical, and commercial piping systems requiring Schedule 80 pressure capacity. Constructed in dark gray Schedule 80 PVC, it delivers the elevated wall thickness and pressure rating required in demanding installations where standard Schedule 40 closure fittings are insufficient and where a pipe end must be sealed definitively, flush, and without the need for threaded fittings or additional transition hardware.

The slip socket interior is sized to accept a 1/2" PVC pipe end for a permanent solvent-cement bond, enclosing the pipe terminus in a clean, dome-shaped cap profile that withstands system pressure from within. Unlike a spigot plug, which closes an unused port on an existing fitting hub, the slip cap terminates the pipe run itself — making it the correct choice when a 1/2" Schedule 80 pipe end is being permanently closed at the end of a distribution line, a dead-leg branch, a pressure test stub, or a stubbed-out future connection point within an all-Schedule-80 assembly. At 1/2", this cap is among the most frequently specified sizes in Schedule 80 terminal closure applications, appearing throughout chemical feed systems, instrument distribution headers, pump discharge stubs, and small-diameter process piping assemblies where 1/2" pipe serves as the most common dedicated service and branch supply diameter in Schedule 80 industrial and chemical systems. The slip cap should not be confused with the FPT cap (848 series), which threads over a male pipe end, the spigot plug (849 series), which cements into a socket fitting hub, or the MPT plug (850 series), which threads into a female port.

Rated to approximately 850 psi at 73°F, this cap is well-suited for demanding pressure service across a broad range of industrial, chemical, and commercial fluid handling applications. Its Schedule 80 PVC composition provides excellent resistance to acids, bases, salts, and chlorinated water, making it a durable long-term closure in corrosive environments where metal caps would degrade, corrode, or add unnecessary weight to the assembly. NSF/ANSI 61 listing confirms suitability for potable water contact, including use in drinking water distribution and treatment systems.

Apply solvent cement to both the pipe end exterior and the fitting socket interior per ASTM D2564 procedures, using a primer appropriate for the pipe and fitting schedule. Insert the pipe fully into the socket and maintain a quarter-turn during assembly for even cement distribution across the joint surface. Ensure full pipe insertion before the cement begins to set — partial insertion can result in an incomplete joint with reduced pressure integrity. Allow adequate cure time before pressurizing the system, and derate pressure ratings for elevated temperatures per published derating curves.

Industries & Applications:

• Industrial Process Piping — Permanently closes 1/2" Schedule 80 PVC pipe ends at dead-leg branches, pressure test stubs, and future connection points on chemical processing, water treatment, and manufacturing distribution assemblies where Schedule 80 pressure ratings are required throughout and a permanent, flush pipe-end closure is specified at small-diameter service terminations
• Chemical Handling — Provides a corrosion-resistant, high-pressure-rated permanent closure for 1/2" Schedule 80 pipe ends in systems conveying acids, caustics, fertilizer solutions, and other fluids incompatible with metal caps, particularly at chemical feed line stubs, injection point dead legs, metering system branch terminations, and unused small-diameter distribution outlets
• Commercial Plumbing — Caps 1/2" Schedule 80 PVC pipe ends at end-of-line locations, pressure test terminations, and stubbed-out future service connections in high-pressure or exposed commercial building water supply systems where Schedule 80 fittings are specified throughout the assembly at small-diameter service connections
• Irrigation & Water Distribution — Permanently closes 1/2" Schedule 80 pipe ends at zone terminations, instrument stub-outs, and future lateral connection points in high-pressure agricultural and municipal irrigation systems where Schedule 80 pressure ratings are specified at critical small-diameter service and branch supply termination points
• Water Treatment & Aquaculture — Used to permanently close 1/2" pipe ends on recirculating system distribution branches, chemical dosing line stubs, filter feed laterals, and monitoring point dead legs where NSF/ANSI 61 compliance and Schedule 80 chemical resistance are required at terminal pipe locations throughout the all-socket assembly
• HVAC & Mechanical Systems — Caps 1/2" Schedule 80 PVC pipe ends on cooling tower chemical feed stubs, chilled water service line terminations, and instrument distribution dead legs in chemically treated water systems requiring elevated pressure ratings at small-diameter terminal pipe closure points
