Tee, Slip x Slip x FPT 10" x 10" x 2" (C602-622)

The 10" x 10" x 2" PVC Schedule 40 Slip x Slip x FPT Tee (Part No. C602-622) is a large-diameter, three-port branch fitting that maintains a full 10-inch solvent-weld mainline run while introducing a 2-inch female pipe thread (FPT) branch outlet — combining the permanence and structural integrity of a solvent-welded main run with the direct, tool-free compatibility of a threaded branch connection in a single fitting body. The two run ports are slip (socket) configuration, accepting 10-inch PVC pipe or spigot fittings via solvent-weld connection, while the 2-inch FPT branch accepts any standard 2-inch male pipe thread (MPT) fitting, valve, instrument, or threaded device directly — no solvent welding, no adapter fittings, and no transition hardware required at the branch point.

The 2-inch FPT branch outlet is the smallest threaded branch size in the C602 series for 10-inch mainline runs — and that sizing tells a precise story about the application this fitting is designed to serve. With a cross-sectional area reduction of approximately 25:1 from the 10-inch mainline to the 2-inch branch, this fitting is decisively not a flow-splitting or zone-distribution device. It is a precision access point — a means of connecting instrumentation, monitoring equipment, chemical injection assemblies, air release devices, sample taps, pressure sensing ports, small-diameter blow-off assemblies, and service connections that operate at flow rates entirely independent of and incidental to the high-volume flow moving through the 10-inch main. The 2-inch FPT branch is the standard interface size for a wide range of these devices, and the threaded connection makes them directly installable, removable, and replaceable without disturbing the solvent-welded mainline structure on either side of the tee.

The distinction between this fitting and the 3-inch FPT variant (C602-623) and 4-inch FPT variant (C602-624) is meaningful and worth understanding at the specification stage. The 2-inch branch is the appropriate selection when the branch device has a 2-inch male NPT inlet — the most common connection size for combination air release and vacuum break valves, many pressure gauge manifolds, standard chemical injection assemblies, water quality instrumentation, and small-diameter blow-off risers. Specifying the correct branch thread size at the tee body eliminates the need for a threaded reducing bushing between the tee and the branch device — keeping the branch assembly compact, minimizing the number of threaded joints in the branch stack, and reducing the potential for thread-joint leak paths at a point in the system that is intended to be both serviceable and reliable over an extended operational life.

The threaded branch outlet also defines the maintenance posture of the branch connection. Unlike a solvent-welded branch — which is permanent and requires cutting to remove — a threaded branch connection can be broken, serviced, retorqued, or replaced with hand tools and a strap wrench in a fraction of the time and labor of a solvent-weld branch repair. On large-diameter transmission mains and industrial process headers where unplanned downtime is costly and planned maintenance access to branch devices is a routine operational requirement, this replaceability is a functional design feature that justifies the specification of a mixed-connection tee over an all-slip body with a threaded adapter downstream.

This Charlotte Pipe SKU — identified by the C602 part number prefix — is a nationally distributed, contractor-recognized fitting that supports consistent availability across supply chains serving municipal water utilities, industrial contractors, and large-scale irrigation installers. The 2-inch FPT branch configuration at 10-inch run size is a specialty stocking item that many local distributors carry inconsistently — making a reliable online source with confirmed availability a meaningful procurement consideration for contractors and engineers working to schedule on large-diameter system installations.

Manufactured from virgin PVC compound to ASTM D2466 standards, this tee delivers the corrosion resistance, chemical compatibility, and long-term service life that make Schedule 40 PVC the standard material across water, wastewater, irrigation, and industrial piping environments. NSF/ANSI 61 certification confirms suitability for potable water contact, extending its application range to municipal water distribution, water treatment infrastructure, and food-adjacent process piping in addition to its broad industrial and agricultural markets.

Specifications:

Note: Pressure ratings decrease with increasing pipe diameter. Always apply appropriate thread sealant — PTFE tape or pipe dope rated for PVC — to the male threads before assembly on the FPT branch port. Do not over-torque threaded connections on PVC; hand-tight plus 1–2 turns with a strap wrench is the recommended installation practice to avoid cracking the female thread socket. The 25:1 cross-sectional area reduction from the 10-inch run to the 2-inch branch produces a substantial increase in branch flow velocity — confirm branch device compatibility and hydraulic requirements with the device manufacturer before installation.

Industries & Applications:

• Municipal Water Distribution — Installs on 10-inch transmission and distribution mains to provide a 2-inch threaded branch connection for combination air release and vacuum break valves, small-diameter blow-off risers, pressure sensing ports, or water quality monitoring connections that require a removable, serviceable threaded interface directly on the mainline fitting body
• Air Release & Vacuum Break Assemblies — The 2-inch NPT male inlet is the standard connection size for many combination air release and vacuum break valves used on large-diameter water transmission mains; the C602-622 provides the tee body for these assemblies directly on the 10-inch main without a separate tee-plus-adapter combination, keeping the assembly compact and the joint count minimal
• Chemical Dosing & Injection Systems — The 2-inch FPT branch outlet accepts standard threaded chemical injection quills, dosing valve assemblies, and metering connections at the branch size most commonly specified for controlled-rate injection applications on large-diameter process and water mains; the threaded connection allows injection assemblies to be removed, cleaned, recalibrated, or replaced without cutting into the mainline; always verify chemical compatibility with the specific fluid and concentration before specification
• Industrial Process Piping — Introduces a 2-inch threaded branch off a 10-inch process supply header for instrumentation taps, pressure relief connections, sample valves, drain points, or monitoring equipment in chemical, pharmaceutical, manufacturing, and power generation facilities where 2-inch NPT is the standard interface for the branch device and threaded connections are preferred for their field replaceability
• Pump Station & Mechanical Room Piping — Used on 10-inch pump discharge or suction headers to provide a 2-inch threaded branch for pressure gauges, compound gauges, pressure transmitters, bypass valves, or drain connections that are mounted directly on the mainline fitting and must be accessible for routine calibration, replacement, or maintenance without disturbing the solvent-welded run
• Water Treatment & Filtration Plants — Integrates into 10-inch process piping headers and distribution manifolds where a 2-inch threaded branch is required for sample taps, chemical feed inlets, water quality probes, or removable instrumentation connections in treatment train piping environments where periodic device access, replacement, or recalibration is a routine operational requirement
• Commercial & Agricultural Irrigation — Provides a 2-inch threaded branch on a 10-inch irrigation mainline for pressure gauges, fertigation injection assemblies, small-diameter zone isolation valves, or water quality monitoring connections that require removability for seasonal maintenance, system adjustment, or equipment replacement without cutting the mainline
• Aquaculture & Recirculating Systems — Used on 10-inch RAS distribution headers to provide threaded connections for dissolved oxygen sensors, water quality monitoring probes, small-diameter drain assemblies, or chemical dosing inlets that must be accessible for periodic calibration, cleaning, or replacement in continuous-duty recirculating facility environments
