Tee Fitting for 2-5/8" Pipe

The K-Flex USA 801-T-100258 is an elastomeric tee fitting designed for 2-5/8 inch tube outside diameter. It suits plumbing professionals insulating pipe junctions in commercial or industrial systems. The unslit design requires installation before final pipe assembly.

Closed-Cell Buna-N/PVC Build

The fitting uses closed-cell Buna-N rubber blended with PVC for flexibility and an R-value of 6.5. Antimicrobial and flame-retardant properties meet a 25 flame spread index and plenum rating. It withstands continuous temperatures from -297 to 220 degrees Fahrenheit.

Upgrade from Basic Wrap Insulation

This pre-formed tee replaces field-fabricated wrap at branch connections, eliminating gaps and reducing labour time. The jump is worth it when plenum-rated, antimicrobial performance is specified and a consistent 1 inch wall thickness is required.

Questions about this item

What does the plenum rating and flame spread index of 25 mean for installation?

The plenum rating allows use in air-handling spaces, and the flame spread index of 25 meets typical building code requirements for low flame spread.

What pipe diameter and wall thickness does this tee fitting accommodate?

It fits a tube outside diameter of 2-5/8 inches with a 1-inch wall thickness for a secure insulation seal.

How is the unslit installation style applied, and what common step is missed?

Slide the unslit tee over the pipe joint before connecting the pipes; the step often missed is positioning it before final assembly.
