Tee, Slip x Slip x Slip PVC Schedule 40 3/4" (401-007)

This 3/4" Schedule 40 PVC Tee (Slip x Slip x Slip) provides the standard three-way all solvent-cement junction at the dominant residential and light commercial irrigation grid and distribution assembly diameter — accepting 3/4" PVC pipe at all three ports for permanent solvent-cement bonds while maintaining the full 3/4" interior diameter through both inline run ends and the perpendicular branch outlet. Constructed in white Schedule 40 PVC, it is the highest-demand entry in the 401 series and the foundational three-way junction fitting in residential landscape irrigation grids, fire suppression branch assemblies, and all-socket 3/4" commercial distribution layouts throughout North American PVC plumbing systems.

All three 3/4" slip socket ends accept 3/4" PVC pipe for permanent solvent-cement bonds — the two run ends forming the continuous inline run and the branch outlet providing a perpendicular departure for the distribution branch run, all at the same 3/4" socket diameter throughout the fitting body. This full-size equal-run, equal-branch configuration is the standard all-socket tee for every three-way junction point in a 3/4" all-socket PVC distribution assembly where the branch must continue as a 3/4" socket pipe run — the correct choice when all three connected pipe runs are the same 3/4" all-socket diameter and the branch must carry the same nominal flow capacity as the run. This all-slip configuration should not be confused with the confirmed 402-007 (3/4" Slip x Slip x FPT, confirmed in this session), which provides a 3/4" female-threaded branch outlet for receiving a 3/4" male-threaded valve, solenoid, or service component rather than continuing a socket pipe run — the most critical disambiguation at this size given both are confirmed full-size 3/4" tees in this catalog session and the correct choice between them is determined entirely by the branch connection type required at the junction; nor with the confirmed 401-095 (3/4" x 1/2" Reducing Tee, confirmed in this session), which maintains 3/4" run ends but steps the branch down to 1/2" for a small-bore drip or service lateral departure rather than continuing a full-size 3/4" branch run; nor with the confirmed 401-074 (1/2" x 1/2" x 3/4" Bullhead Tee), which has a larger 3/4" branch than its 1/2" run ends rather than equal sizes throughout. At 3/4", the full-size all-slip tee appears at every three-way junction point in residential landscape irrigation grid and mainline assemblies; at each branch point in fire suppression grid headers and cross-main assemblies; at distribution header T-intersections in commercial plumbing socket supply systems; and throughout all-socket 3/4" process water distribution and chemical handling assemblies wherever the branch must continue as a 3/4" socket pipe run at the junction.

Rated to approximately 480 psi at 73°F, this tee is suited for standard commercial and light industrial pressure service. Its PVC composition provides excellent resistance to corrosion, scale, chlorinated water, and a broad range of chemical exposures, making it a reliable long-term alternative to metal fittings in moisture-prone or chemically active environments. NSF/ANSI 61 listing confirms suitability for potable water contact.

Apply solvent cement to both the pipe end and fitting socket at each port per ASTM D2564 procedures, using a primer appropriate for the pipe and fitting schedule. Insert pipe fully into each socket and maintain a quarter-turn during assembly for even cement distribution across the joint surface. Allow adequate cure time before pressurizing the system, and derate pressure ratings for elevated temperatures per published derating curves.

Industries & Applications:

• Irrigation & Water Distribution — Provides the standard all-socket three-way junction at every branch point in 3/4" residential and light commercial landscape irrigation grid assemblies, mainline distribution T-intersections, and zone header branch points where the branch must continue as a full-size 3/4" socket pipe run — the highest-demand three-way junction fitting in residential irrigation at the dominant all-socket grid and lateral distribution diameter
• Fire Suppression Systems — Serves as the standard three-way junction fitting at cross-main branch points, grid header T-intersections, and lateral branch departures in light-hazard and residential Schedule 40 PVC fire suppression systems where the branch line must continue at the full 3/4" socket diameter and all-cemented construction is maintained throughout the grid assembly
• Commercial Plumbing — Provides all-socket three-way distribution junctions at T-intersection points on 3/4" socket PVC supply headers, branch supply distribution runs, and commercial building water distribution assemblies where all three pipe runs are 3/4" socket PVC and a permanent all-cemented branch junction maintains full mainline and branch flow capacity through the fitting body
• Industrial Process Piping — Serves as the standard three-way all-socket junction at branch points on 3/4" process water distribution headers, chemical feed lateral distribution runs, and service manifold supply branch assemblies in water treatment, chemical processing, and manufacturing facilities where all-cemented 3/4" socket construction is maintained at every three-way junction throughout the distribution layout
• Chemical Handling — Provides a corrosion-resistant all-socket three-way junction for 3/4" chemical feed distribution lines, dosing system lateral headers, and injection line branch assemblies conveying acids, caustics, fertilizer solutions, and other fluids incompatible with metal fittings — the permanent solvent-cement bond at all three ports providing equivalent long-term chemical resistance to the fitting body throughout the all-socket distribution assembly
• Water Treatment & Aquaculture — Used at all-socket three-way branch junction points on 3/4" process water distribution headers, filter approach lines, recirculating system distribution runs, and treatment equipment supply assemblies where NSF/ANSI 61 compliance and full all-cemented construction are required at every three-way junction throughout the system
