Tee, Slip x Slip x Slip PVC Schedule 40 2-1/2" (401-025)

The 401-025 is a 2-1/2-inch PVC Schedule 40 tee with three slip (socket) ends — one on each run and one on the branch — providing a straightforward, all-solvent-welded solution for splitting or combining flow in a straight pipe run. The equal-end configuration means all three connections accept 2-1/2-inch Schedule 40 pipe, making this tee the go-to choice when no reduction is needed at the branch and when maximum flow capacity through the fitting is the design priority.

Manufactured to ASTM D2466 and produced in standard white PVC compound, the 401-025 integrates seamlessly with Schedule 40 PVC pipe and fittings from all major manufacturers. It is NSF/ANSI 61 listed, qualifying it for use in potable water distribution systems and water treatment facilities where material certification is required by specification or code.

The all-slip design creates a fully permanent, solvent-cemented assembly at all three connections — the preferred configuration where no future disassembly of the tee itself is anticipated. For installations requiring serviceability at the branch or run connections, a union or flanged spool should be incorporated upstream of the tee rather than substituting a threaded-end fitting at this diameter. A standard medium-bodied Schedule 40 PVC cement is appropriate for all three socket connections at 2-1/2 inches. Follow manufacturer preparation procedures, including priming both mating surfaces and applying cement uniformly to the pipe and socket before insertion with a slight quarter-turn to distribute the cement evenly around the joint.

At 2-1/2 inches, the 401-025 is commonly encountered in mains-level commercial plumbing distribution, irrigation mainlines, and process piping headers where branch takeoffs must maintain substantial flow capacity without stepping down to a smaller connection.

Specifications

⚠️ Pressure rating note: Confirm rated psi at 73°F from the current Charlotte Pipe 401-025 data sheet before publishing. Schedule 40 pressure capacity at 2-1/2" is lower than at smaller diameters and should be stated accurately.

Industries & Applications

Commercial & Industrial Plumbing The 2-1/2" all-slip tee is a distribution-level fitting in commercial plumbing systems — used in main supply runs, mechanical room headers, and building service lines where a full-diameter branch takeoff is needed without flow restriction at the junction.

Municipal Water Distribution & Treatment NSF/ANSI 61 certification supports use across potable water infrastructure, including treatment plant interconnects, distribution laterals, and utility service mains where sanitary material compliance is required by specification.

Irrigation & Agricultural Systems A natural fit for commercial agricultural and landscape irrigation mainlines, where 2-1/2" is a common header size for zone manifolds and lateral distribution trees serving large turf areas, row crops, or greenhouse facilities.

Industrial Process Piping In chemical handling, manufacturing, and process environments operating within PVC's chemical compatibility and temperature range, this tee provides reliable branching capability for coolant lines, wash-down systems, and fluid distribution headers.

Fire Protection Support & Drainage Systems Where PVC Schedule 40 is code-approved for auxiliary, drainage, or non-pressurized support lines in fire suppression systems, the 401-025 enables branch routing without transitioning to a different material or fitting schedule.

Aquaculture & Pool/Spa Systems The chemical resistance and NSF listing of white Schedule 40 PVC make this tee appropriate for recirculating water systems, filter manifolds, and chlorinated service loops where branch distribution points are needed at the 2-1/2" mainline level.

HVAC & Mechanical Systems Used in chilled water distribution, cooling tower makeup supply, and other mechanical piping applications where PVC is the specified material and a full-flow tee branch is required at the 2-1/2" service level.
