Tee, FPT x FPT x FPT PVC Schedule 80 3/4" (805-007)

This 3/4" Schedule 80 PVC FPT × FPT × FPT Tee provides a full-size, all-threaded branch connection in a fully threaded Schedule 80 PVC pressure piping system. All three female NPT threaded ends receive standard 3/4" male-threaded pipe, nipples, or MPT fittings — the two run ports maintaining the straight-through threaded run while the branch outlet presents an equal 3/4" FPT opening perpendicular to the run, with no size reduction at any end of the tee body.

The all-threaded construction is the defining feature of the 805-007 within the Schedule 80 tee family. Where the 801-series Slip × Slip × Slip tee serves solvent-welded PVC pipe systems with socket ends at all three positions, and the 802-series Slip × Slip × FPT tee bridges a solvent-welded run to a threaded branch outlet, the 805-007 is the tee of choice wherever all three connections in the assembly are threaded — both sides of the through-run and the branch outlet all receiving nipples, MPT-terminated fittings, or male-threaded pipe ends. No solvent cement, primer, or cure time is involved at any end of the fitting; the complete tee assembly is made up with PTFE tape and thread sealant at three NPT connections in a fully threaded configuration.

This all-threaded construction serves several distinct system contexts. In fully threaded Schedule 80 assemblies — mechanical rooms, equipment bays, process connections, and instrument supply systems built entirely with threaded pipe, nipples, and fittings rather than solvent-welded PVC runs — the 805-007 is the standard branch tee that holds the threaded layout together at every three-way split. In hybrid systems combining solvent-welded PVC mains with threaded branch sub-assemblies, the 805-007 appears within the threaded branch portions, taking nipples on all three ports without requiring any solvent cement work at the tee position. In retrofit and repair situations where existing threaded infrastructure must be branched without introducing cement work into an established threaded system, the 805-007 threads directly into the existing assembly without modification.

At 3/4", the 805-007 serves one of the most common pipe sizes in small-bore commercial and industrial Schedule 80 threaded systems. Three-quarter inch NPT is a standard size across instrument supply lines, chemical dosing branches, control valve connections, equipment supply runs, and secondary distribution headers throughout industrial and commercial facilities. The equal tee at this size — delivering a full 3/4" FPT branch outlet matching the run port size — is a high-frequency component in any threaded Schedule 80 installation where the branch must carry the same capacity as the run.

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 corrode, scale, or seize on threads over time. NSF/ANSI 61 listing confirms suitability for potable water contact.

Rated to 690 psi at 73°F, this tee handles standard to elevated pressure service across a wide range of fluid handling applications in threaded Schedule 80 systems. Apply PTFE tape or compatible pipe thread sealant to all male threads before engaging any of the three FPT ends. Hand-tighten plus one to two turns at each port — do not over-torque PVC female threads, as excessive force risks cracking the tee body at the thread root, particularly at the branch port where the body geometry is most constrained. When assembling a nipple-tee-nipple run, make up the run ports evenly before engaging the branch port, and avoid applying torsional stress to one port while tightening another. Apply published pressure derating factors for service temperatures above 73°F.

Industries & Applications:

• Fully Threaded Schedule 80 Systems — Provides a full-size 3/4" FPT branch outlet at every three-way split in mechanical rooms, equipment bays, process connection assemblies, and instrument supply systems built entirely with threaded Schedule 80 PVC pipe, nipples, and fittings — the foundational branch tee in any all-threaded 3/4" Schedule 80 system layout where no solvent cement work is performed at the tee position
• Industrial Process Piping — Branches a 3/4" threaded run at chemical distribution headers, instrument supply mains, pump manifold branch points, and equipment supply connections in water treatment, chemical processing, and manufacturing facility piping where the threaded system construction requires an all-FPT tee body at the branch position
• Chemical Dosing & Injection Systems — Provides a full-size threaded branch point on 3/4" Schedule 80 PVC chemical feed headers, reagent distribution runs, and dosing loop assemblies where parallel branch feeds, equipment supply splits, and zone distribution takeoffs must be accomplished within a fully threaded system without cement joints at the tee body
• Commercial Plumbing — Branches 3/4" threaded runs at equipment supply connections, valve assembly branch points, manifold distribution positions, and secondary zone takeoffs in mechanical room and building water supply Schedule 80 systems where the piping is constructed with threaded fittings and nipples rather than solvent-welded pipe runs
• Threaded System Repair & Extension — Introduces a new branch into an existing 3/4" threaded Schedule 80 PVC system by threading the 805-007 tee into a nipple run between two existing fittings — adding a branch distribution point without cutting solvent-cemented pipe or performing cement work in an established threaded assembly
• Water & Wastewater Treatment — Distributes 3/4" threaded runs at chemical dosing branch points, instrument supply splits, sampling manifold connections, and parallel equipment distribution positions along Schedule 80 PVC threaded process headers in municipal and industrial water treatment and distribution facilities
• HVAC & Mechanical Systems — Provides a full-size 3/4" threaded branch point on Schedule 80 PVC cooling tower chemical feed lines, treated water distribution headers, and glycol system threaded branch assemblies where all-threaded construction is specified at the tee position in commercial mechanical system piping
