Plug, Spigot PVC Schedule 80 2" (849-020)

This 2" Schedule 80 PVC Spigot Plug provides a permanent, solvent-cemented closure for any open 2" female slip socket port in a Schedule 80 PVC pressure piping system. The spigot end — a male plain end with an OD matching standard 2" PVC pipe — inserts directly into a 2" female slip socket opening for solvent cement joining, sealing the port from the inside with a fused, pressure-rated closure that becomes an integral part of the fitting body once cured.

Correctly identifying the application for a spigot plug requires understanding where it sits relative to the other Schedule 80 closure fittings. The spigot plug closes open slip socket ports by inserting into them — the inverse of a slip cap, which slides over a pipe end or spigot to close it from the outside. When a tee branch outlet, cross port, wye branch opening, or any other fitting socket port must be sealed and the port presents a female slip socket opening, the spigot plug is the correct and most direct closure: insert, cement, done. No adapter, nipple, or intermediate fitting is required to bridge between the open socket and the closure component.

This directness is the primary efficiency advantage of the spigot plug over threaded closure alternatives at slip socket positions. Where sealing an open socket port with a threaded plug would require first installing a female adapter into the socket — adding a fitting, a joint, and axial length to the assembly — the 849-020 accomplishes the closure in a single fitting with a single solvent-cemented joint at the socket face.

Like all solvent-cemented PVC closures, the spigot plug produces a permanent joint. Once the cement is cured, the plug cannot be removed without cutting into the fitting body. This permanence is the correct design choice at socket ports that are genuinely terminal — unused branch outlets on manifolds and headers that will not be commissioned, spare ports on distribution tees in completed systems, and cross outlets on permanently configured process headers. Where future access at the socket port is possible or planned, the serviceable alternative is to install a female adapter into the socket and close it with a removable MPT plug (850-series), preserving the option to reopen the port without cutting.

Manufactured in dark gray Schedule 80 PVC, this spigot plug delivers the increased wall thickness and mechanical strength required in industrial, chemical, and commercial pressure piping where Schedule 40 ratings are insufficient. PVC's broad chemical resistance covers acids, bases, salts, chlorine, and most common process fluids, ensuring long service life at socket closure points in corrosive environments where metal plugs would corrode, pit, or contaminate the fluid stream. NSF/ANSI 61 listing confirms suitability for potable water contact.

Rated to 400 psi at 73°F, this plug handles standard pressure service across a wide range of fluid handling applications. For installation, clean and dry the spigot exterior and receiving socket interior thoroughly before application. Apply purple PVC primer to both mating surfaces — the full spigot end and the full socket bore — then apply a uniform coat of Schedule 80 PVC solvent cement to both surfaces before inserting. Push the spigot fully into the socket with a slight quarter-turn twist and hold firmly for 30 seconds to prevent pushback while the cement sets. Allow full cure time per the cement manufacturer's temperature and humidity guidelines before pressurizing the system. Apply published pressure derating factors for service temperatures above 73°F.

Industries & Applications:

• Tee, Cross & Wye Branch Sealing — Permanently closes unused 2" female slip socket branch outlets on Schedule 80 tees, crosses, wyes, and manifold assemblies in process piping, water distribution, and chemical handling systems — the primary application for spigot plugs across all industries served by Schedule 80 PVC; a single fitting inserted directly into the open socket produces the closure without intermediate adapters or threaded hardware
• Industrial Process Piping — Seals spare and decommissioned slip socket ports on process headers, pump manifolds, chemical distribution systems, and equipment stub connections in water treatment, chemical processing, and manufacturing facilities where permanent closure of unused socket outlets is required without future-access provisions
• System Commissioning & Pressure Testing — Provides a permanent, schedule-consistent closure at open 2" slip socket positions during construction and commissioning of Schedule 80 PVC piping systems — ensuring test pressure is contained at socket port closures without rating discontinuity at the sealed fitting
• Commercial Plumbing — Caps unused slip socket branch outlets on 2" tees, manifold assemblies, and distribution fittings in mechanical room and building water supply Schedule 80 systems where the branch port will not be commissioned and permanent closure is appropriate
• Chemical Handling — Delivers a permanent, corrosion-resistant socket port closure on chemical storage tank outlet fittings, reagent distribution manifolds, and chemical feed headers in systems handling acids, caustics, and aggressive fluids where metal plugs would corrode or contaminate the process stream at unused branch points
• Water & Wastewater Treatment — Closes decommissioned slip socket branch connections, unused filter vessel socket ports, and spare manifold outlets on 2" Schedule 80 PVC process piping in municipal and industrial water treatment and distribution facilities
• Irrigation & Agricultural Systems — Permanently seals unused slip socket branch outlets on 2" tees and distribution manifolds in commercial irrigation mainlines, pump station headers, and agricultural water supply systems where spare ports on multi-outlet manifolds are closed at installation and not anticipated to be reopened
