Tee, Slip x Slip x Slip PVC Schedule 80 1/2" (801-005)

This 1/2" Schedule 80 PVC Equal Tee provides a full-size, solvent-cemented branch outlet off a 1/2" PVC main run, with all three slip socket ends accepting standard 1/2" PVC pipe for solvent cement joining. The two run ports maintain the straight-through flow path of the main, while the branch outlet presents an equal 1/2" socket perpendicular to the run — delivering the same full pipe diameter at the branch as at the run, with no size reduction at the tee body.

At 1/2", the 801-005 serves one of the most prevalent small-bore pipe sizes in commercial and industrial Schedule 80 systems. One-half inch PVC pipe appears across a broad and diverse range of applications — chemical dosing and injection system headers, instrument supply distribution runs, control system piping, branch supply lines, small equipment feed connections, and secondary zone distribution branches throughout industrial and commercial facilities. This breadth distinguishes the 1/2" equal tee from its 3/8" counterpart (801-003), which operates almost exclusively within the narrow instrument supply and gauge line niche. At 1/2", the all-socket equal tee serves chemical dosing systems as readily as instrument supply headers, branch supply lines as readily as control panel piping, and small equipment feeds as readily as secondary distribution networks — a genuine multi-application pipe size where the equal tee appears frequently across a wide variety of system layouts.

The all-socket construction of the 801-005 is the correct configuration wherever both the upstream run and the downstream branch are solvent-welded 1/2" PVC pipe. When all three connections at the tee body are plain PVC pipe ends joined by solvent cement — as they are in any fully solvent-welded Schedule 80 system — the 801-005 is the correct tee selection. The 805-005 FPT × FPT × FPT equal tee (previously written) serves the same 1/2" pipe size in fully threaded Schedule 80 assemblies where all three connections are male-threaded nipples or fittings. The 802-series Slip × Slip × FPT tee serves configurations where the run is solvent-welded but the branch requires a female-threaded outlet for a threaded downstream component. When all three connections are cemented pipe in a fully solvent-welded system, the 801-005 is the direct and correct selection.

Within the 801-series equal tee range, the 1/2" entry occupies a well-defined intermediate position. The 3/8" entry (801-003) carries the highest pressure rating (~1300 psi) at the finest bore, serving an almost exclusively instrument supply application niche. The 3/4" entry (801-007) carries a lower rating (~690 psi) at a broader secondary distribution pipe size. The 1/2" entry sits between them — at approximately 850 psi it is well suited for the high-pressure chemical dosing, instrument supply main, and control system piping applications where 1/2" Schedule 80 PVC is specified for its pressure performance advantage over Schedule 40 equivalents at this common small-bore pipe size.

The equal tee provides full-size branch capacity at all three ports — the correct configuration when the branch must carry the same flow as the run. When the branch requires a smaller outlet, a reducing tee is the appropriate selection; when the branch requires a threaded interface, the 802 or 805 series applies. The 801-005 is the foundational branch fitting at 1/2" Schedule 80 wherever a full-size, all-cement branch is the requirement.

Manufactured in dark gray Schedule 80 PVC, this tee 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, providing long service life in corrosive environments where metal tees would degrade or contaminate chemical dosing lines, instrument supply systems, and small-bore process connections. NSF/ANSI 61 listing confirms suitability for potable water contact.

Rated to 850 psi at 73°F, this tee handles standard to elevated pressure service across the full range of 1/2" Schedule 80 PVC applications. Three separate solvent-cemented joints must be made at installation. Clean and dry each pipe end and socket interior before application. Apply purple PVC primer to all mating surfaces — both run port sockets, the branch socket, and all three corresponding pipe ends. Apply a uniform coat of Schedule 80 PVC solvent cement to both the pipe end and socket interior at each joint before inserting. Insert each pipe with a slight quarter-turn twist and hold firmly for 30 seconds to prevent pushback. Stagger the three joints where possible and allow full cure time per the cement manufacturer's temperature and humidity guidelines before pressurizing. Apply published pressure derating factors for service temperatures above 73°F.
