Cap, Slip PVC Schedule 40 1/2" (447-005)

This 1/2" Schedule 40 PVC Slip Cap provides a permanent, pressure-rated solvent-cement closure for any standard 1/2" PVC pipe end, terminating the pipe run with a full-strength cemented bond equivalent in integrity to a standard pipe-to-fitting joint. Constructed in white Schedule 40 PVC, it is the smallest confirmed entry in the 447 series and the highest-pressure rated — carrying approximately 600 psi at 73°F — completing the most comprehensively documented single-size closure family in this catalog session at the standard small-bore drip, micro-irrigation, and instrument distribution diameter.

The slip socket interior is sized to accept the exterior of any standard 1/2" PVC pipe end and is solvent-cemented in place to form a permanent, leak-free closure — identical in installation method and joint strength to cementing a pipe end into any other Schedule 40 socket fitting. This closure method is the correct choice when a 1/2" pipe end must be permanently sealed and no future access to the port is anticipated — as opposed to the FPT cap (448-005 confirmed in this catalog session), which threads over a 1/2" male NPT pipe end and can be removed and reinstalled for future access; the MPT plug (450-005 confirmed in this session), which threads into a 1/2" female port and also offers removability; or the spigot plug (449-005 confirmed in this session), which inserts into and cements into a 1/2" socket fitting hub interior rather than socketing over a pipe end exterior. The slip cap is the correct choice when terminating a pipe end directly — without requiring a fitting hub between the pipe end and the closure point — while the spigot plug is correct when closing a spare socket port on an existing fitting body. At 1/2", this cap most commonly permanently terminates dead-end socket drip emitter supply laterals and micro-irrigation sub-header pipe ends at grid layout boundaries; closes pipe ends during drip system pressure testing; seals spare 1/2" socket pipe stub ends at phased installation limits in drip grid assemblies; permanently terminates 1/2" socket instrument supply pipe ends at system boundaries; and closes spare 1/2" socket pipe run ends in chemical injection and process water distribution assemblies — the standard terminal closure for all-socket 1/2" PVC pipe run ends where no future access is required and the permanent solvent-cement bond maintains all-socket system integrity throughout. Together with the confirmed 448-005 (FPT Cap), 449-005 (Spigot Plug), and 450-005 (MPT Plug), 447-005 completes the confirmed four-entry 1/2" closure family — the most fully documented single-size closure set across all nominal sizes in this catalog session — covering every primary closure scenario at the standard small-bore service and drip distribution diameter.

Rated to approximately 600 psi at 73°F — the highest confirmed pressure rating in the 447 series — this cap is suited for standard commercial and light industrial water distribution, irrigation, and instrument service applications well within its pressure class. NSF/ANSI 61 listing confirms suitability for potable water contact.

Apply solvent cement to both the pipe end exterior and the fitting socket interior per ASTM D2564 procedures, inserting fully and maintaining a quarter-turn during assembly. Because the slip cap is a permanent closure, confirm the pipe end is intended for permanent sealing before cementing — the joint cannot be disassembled after cure without cutting into the pipe; if future access is anticipated, the FPT cap (448-005 confirmed in this session) provides a removable threaded alternative at a male-threaded pipe end, or the MPT plug (450-005) provides a removable alternative at a female-threaded port. Allow adequate cure time before pressurizing, and derate pressure ratings for elevated temperatures per published derating curves.

Industries & Applications:

• Drip & Micro-Irrigation Systems — Permanently terminates dead-end 1/2" socket drip emitter supply laterals, micro-irrigation sub-header pipe ends, and zone distribution pipe stubs at grid layout boundaries, phased installation limits, and system pressure test points in residential and light commercial drip and micro-irrigation assemblies where the sealed pipe end requires no future access and a permanent solvent-cement closure maintains all-socket assembly integrity throughout the 1/2" lateral distribution grid
• Irrigation & Water Distribution — Permanently closes spare 1/2" socket pipe stub ends, dead-end lateral supply pipe terminations, and system boundary pipe ends in residential and light commercial all-socket irrigation assemblies where the 1/2" lateral diameter is the standard drip supply and small-bore zone distribution diameter requiring permanent pipe end closures at unused or boundary termination points throughout the socket grid layout
• Instrument & Process Piping — Provides a permanent solvent-cement closure at dead-end 1/2" socket instrument supply pipe runs, system boundary pipe ends, and spare pipe stubs in manufacturing, water treatment, and laboratory facilities where all-cemented construction is maintained at every permanently sealed 1/2" pipe end throughout the small-bore instrument distribution layout
• Chemical Handling — Delivers a corrosion-resistant permanent socket closure at 1/2" pipe end termination points in chemical feed distribution assemblies, pump station socket piping, and injection system supply pipe stubs conveying acids, caustics, fertilizer solutions, and other fluids incompatible with threaded metal closures — the solvent-cement bond providing equivalent long-term chemical resistance to the fitting body itself at each permanently sealed 1/2" pipe end
• Fire Suppression Systems — Permanently closes dead-end 1/2" socket sprinkler supply drops, spare branch run pipe stubs, and grid lateral pipe end terminations in light-hazard and residential Schedule 40 PVC fire suppression assemblies where unused 1/2" socket pipe run ends must be permanently sealed in all-cemented construction throughout the grid layout
• Water Treatment & Aquaculture — Used to permanently seal dead-end 1/2" socket distribution pipe runs, spare outlet pipe stubs, and treatment system pipe run boundaries in filter manifold assemblies, chemical dosing distribution layouts, and treatment system socket piping where NSF/ANSI 61 compliance and long-term chemical resistance are required at all permanently sealed 1/2" pipe ends throughout the all-cemented assembly
