Tee, Slip x Slip x FPT PVC Schedule 40 5" x 5" x 2-1/2" (402-487)

The 5" x 5" x 2-1/2" PVC Schedule 40 Tee (402-487) combines a 5" slip x slip inline run with a 2-1/2" female pipe thread (FPT) branch outlet — providing a single-fitting solution for systems where a threaded, serviceable branch connection must be integrated directly into a 5" primary run without a secondary adapter at the branch point. The two 5" slip ports accept standard Schedule 40 pipe for permanent, solvent-welded inline joints, while the 2-1/2" FPT branch accommodates any standard 2-1/2" male-threaded valve, instrument, gauge, strainer, or equipment connection that requires periodic removal or replacement without disturbing the upstream and downstream solvent-welded joints on the 5" run.

Compared to the adjacent 402-488 (5" x 5" x 3" FPT branch), the 402-487 steps the branch down an additional half-inch to 2-1/2" — suited to systems where the branch serves a moderate-flow service connection, a smaller valve or strainer, or an equipment inlet that is specified at 2-1/2" rather than 3". The practical distinction between these two SKUs is narrow but meaningful in engineered system design: buyers sourcing either fitting are working from a specific document where the branch size is called out precisely, and the 2-1/2" designation reflects a deliberate design choice rather than a field substitution.

The mixed slip-and-thread configuration eliminates the need for a secondary threaded adapter or street fitting at the branch, reduces total joint count at the tee, and keeps the branch assembly compact — a recurring advantage in systems where the threaded branch port serves a component that must remain accessible and removable over the system's service life. At 5" on the run, this fitting sits in a specialty diameter range where buyers are almost always sourcing from an engineering document or job-specific material list rather than browsing a general category.

Manufactured from rigid PVC to Schedule 40 specifications and dimensionally compliant with ASTM D2466, the 402-487 ensures compatibility with Schedule 40 pipe and fittings at the 5" slip ends and accepts any standard 2-1/2" MPT connection at the FPT branch. NSF 61 certification confirms suitability for potable water contact across applicable uses.
